Abstract

A stent-graft is provided that includes a bifurcated stent (12) adapted for placement at the bifurcation of a bifurcated body lumen. The stent-graft further includes a graft (20) that lines or covers at least part of the bifurcated stent. The graft defines a fluid passageway from the unbifurcated portion into one of the bifurcated stent branches. A closure prevents fluid from flowing through the second of the branches and into the other branch of the body lumen.

Description

ONE-BRANCH STENT-GRAFT FOR BIFURCATED LUMENS
FIELD OF THE INVENTION
The present invention relates to a one-branch stent-graft for use in bifurcated body lumens. More specifically, the present invention relates to a stent graft including two branches, wherein a closure prevents fluid from flowing to one of the branches.
BACKGROUND OF THE INVENTION
A stent-graft (a stent with a graft layer lining or covering it) is typically used to provide a prosthetic intraluminal wall, e.g., in the case of a stenosis or aneurysm, to provide an unobstructed conduit for blood in the area of the stenosis or aneurysm. A stent-graft may be endoluminally deployed in a body lumen, a blood vessel for example, at the site of a stenosis or aneurysm by so-called "minimally invasive techniques" in which the stent-graft is compressed radially inwards and is delivered by a catheter to the site where it is required, through the patient's skin, or by a "cut down" technique at a location where the blood vessel concerned is accessible. When the stent-graft is positioned at the correct location, the stent-graft is caused or allowed to re-expand to a predetermined diameter in the vessel.
A one branch design stent-graft is typically utilized at a native vessel bifurcation to direct fluid into only one of the branches of the bifurcation.
For example, an aorto-uni-iliac stent-graft provides an unobstructed conduit for blood to flow from the aorta through only one of the two iliacs. As used in the aorta, blood flows through the single branch stent-graft to the bifurcated vessel branch of the native bifurcation that contains the stent-graft, while blood is prevented from flowing to the other bifurcated branch of the native bifurcation.
Typical single branch design stent-grafts have a tendency to work their way distally from the originally deployed position. It will be appreciated by a person skilled in the art that it is desirable to prevent stents from migrating out of position. In particular, where the site of desired application of the stent or prosthesis is a native vessel bifurcation, the distal migration associated with the use of the prior art prostheses constitutes a significant disadvantage.
SUMMARY OF THE INVENTION
According to one aspect, the present invention provides a stent-graft for bypassing one branch of a bifurcated body lumen, the body lumen having an unbifurcated region and at least first and second bifurcated branches extending therefrom, the stent-graft comprising: a bifurcated stent comprising an unbifurcated portion, first and second branches extending therefrom to first and second distal portions and a stent bifurcation therebetween, wherein the bifurcated stent is adapted for placement with the stent bifurcation adjacent a bifurcation of the body lumen and wherein the first and second stent branches are adapted to extend into the corresponding first and second bifurcated branches of the body lumen; a graft lining or covering which lines or covers at least part of the bifurcated stent and defines a fluid passageway from the unbifurcated portion into the first branch; and a second stent-graft having a fluid passage allowing fluid flow to the first branch and a closure preventing fluid flowing to the second branch; wherein the closure is placed in the unbifurcated portion of the bifurcated stent and extends into only the first branch of the bifurcated stent.
According to another aspect, the invention provides a stent-graft, adapted for placement at a native vessel bifurcation, the stent-graft comprising: a straight bifurcated stent comprising a proximal portion adapted for placement in an unbifurcated region of the native bifurcation and two distal portions, the first of which is adapted to extend from the unbifurcated region of the native bifurcation into one of the bifurcated branches of the native bifurcation, the second of which is adapted to extend toward the other bifurcated branch of the native bifurcation; a graft lining or covering which extends from the proximal portion of the straight bifurcated stent to the distal portions of the straight bifurcated stent; and a tapered second stent comprising (i) a proximal tapered portion adapted for placement in the proximal portion of the straight bifurcated stent, (ii) a distal portion adapted for placement in the first distal portion of the straight bifurcated stent, and (iii) a second graft lining or covering which extends from the proximal portion of the tapered stent to the distal portion of the tapered stent, wherein the tapered second stent defines a fluid passage to the first distal portion of the straight bifurcated stent and is closed to fluid passage into the second distal portion of the straight bifurcated stent.
According to a further aspect, the invention provides a stent-graft, adapted for placement at a native vessel bifurcation, the stent-graft comprising: a straight bifurcated stent comprising a proximal portion adapted for placement in an unbifurcated region of the native bifurcation and first and second branches extending from the proximal portion to first and a second distal portions, wherein the first stent branch is adapted to extend from the unbifurcated region of the native bifurcation into the first bifurcated branches of the native bifurcation, wherein the second stent branch is adapted to extend toward and into the second bifurcated branch of the native bifurcation, and wherein the bifurcated stent has a stent bifurcation and is adapted for placement with the stent bifurcation adjacent the native bifurcation; a graft lining or covering which extends from the proximal portion of the straight bifurcated stent to the distal portions of the straight bifurcated stent; and a tapered second stent comprising (i) a proximal tapered portion adapted for placement in the proximal portion of the straight bifurcated stent, (ii) a distal portion adapted for placement in the first distal portion of the straight bifurcated stent, and (iii) a second graft lining or covering which extends from the proximal portion of the tapered stent to the distal portion of the tapered stent, wherein the tapered second stent defines a fluid passage to the first distal portion of the straight bifurcated stent and is closed to fluid passage into the second distal portion of the straight bifurcated stent.

DETAILED DESCRIPTION OF THE INVENTION
Although the invention is illustrated and described herein with reference to specific embodiments, the invention is not intended to be limited to the details shown. Rather, various modifications may be made in the details within the scope and range of equivalents of the claims and without departing from the true spirit and scope of the present invention.
io Referring specifically to Figs. 1A-1C, there is shown a stent-graft 10 is adapted for placement at a native vessel bifurcation. The stent-graft 10 includes a bifurcated stent 12 with a proximal portion 14 adapted for placement in an unbifurcated region of the native bifurcation. The bifurcated stent 12 further includes two distal portions 16, 18. The first distal portion 16 is adapted to extend from the unbifurcated region of the native bifurcation into one of the bifurcated branches of the native bifurcation. The second distal portion 18 extends toward the other bifurcated branch of the native bifurcation. A graft lining 20 defines a fluid passage that extends from the proximal portion 14 of the bifurcated stent 12 to the distal portion 16 of the bifurcated stent 12. The graft lining 20 is adapted to extend to one of the bifurcated branches of the native bifurcation, but is closed to the other of the bifurcated branches.
The stent-graft 10 is adapted for placement of the stent bifurcation 22 adjacent the native bifurcation.
Fig. 18 is a detail view of the bifurcated stent 12 illustrated in Fig. 1A.
Typically, the bifurcated stent 12 has a radially compressed configuration for introduction into a lumen, and a radially expanded configuration for deployment within the lumen. In other words, the bifurcated stent 12 is compressed radially inwards and is delivered by a catheter to the site where it is required through the patient's skin, or by a "cut down" technique in which the blood vessel concerned is exposed by minor surgical means at an accessible location thereof. When the stent 12 is positioned at the correct location, the stent 12 is caused or allowed to re-expand to a predetermined diameter in the vessel and the catheter is withdrawn.
Fig. 1C is a detail view of the graft lining 20 illustrated in Fig. 1A. The graft lining 20 is attached to an inside surface of the bifurcated stent 12 (as illustrated in Fig. 1A) by sewing, suturing, or bonding.
-5-.
In use, the stent-graft 10 illustrated in Fig. 1A is juxtaposed or extends across a bifurcation in an artery or vein such as, for example, the bifurcation in the mammalian aortic artery into the common iliac arteries. Such bifurcation is referred to throughout this specification as a native vessel bifurcation. In the case of an abdominal aortic aneurysm ("AAA") in the infrarenal portion of the aorta, which extends into one of the common iliac arteries, the stent-graft 10 is deployed such that the stent bifurcation 22 is placed adjacent the native vessel bifurcation. The first distal portion 16 extends into one of the bifurcated branches of the native bifurcation, while the second distal portion 18 extends toward and into the other bifurcated branch of the io native bifurcation. The tapered shape of the graft lining 20 results in a fluid passage that extends from the proximal portion 14 of the bifurcated stent 12 to the first distal portion 16 of the bifurcated stent 12. In other words, blood flows through the stent-graft 10 to the bifurcated vessel branch of the native bifurcation that contains the first distal portion 16, while blood is prevented from flowing through the stent-graft 10 to is the other bifurcated branch of the native bifurcation that contains the second distal portion 18.
Accordingly, the second distal portion 18 functions not as a fluid passageway, but as a structural member. The relationship among the first distal portion 16, the stent bifurcation 22, and the second distal portion 18, allows the stent 20 graft 10 to straddle or span the native vessel bifurcation when deployed, placing the stent bifurcation 22 adjacent the native vessel bifurcation tending to prevent distal migration. Actual contact between the stent bifurcation 22 and the native vessel bifurcation may prevent the stent-graft 10 from working its way down away from its originally deployed position.
25 In this and other embodiments of the present invention, the stent and graft, respectively, may be formed of conventional materials, such as nitinol and ePTFE.
Referring to Figs. 2A-2D, there is shown another stent-graft 30, adapted for placement at a native vessel bifurcation, includes a bifurcated stent 32 with a proximal portion 34 adapted for placement in an unbifurcated region of the native 30 bifurcation. The bifurcated stent 32 further includes two distal portions 36 and 38. The first distal portion 36 is adapted to extend from the unbifurcated region of the native bifurcation into one of the bifurcated branches of the native bifurcation. The second distal portion 38 extends toward and into the other bifurcated branch of the native bifurcation. A graft lining or covering 40 (graft covering 40 is represented in Fig. 2A) 35 defines a fluid passage that extends from the proximal portion 34 of the bifurcated stent 32 to the distal portions 36 and 38 of the bifurcated stent 32. An occluder device 42 is adapted for placement in the second distal portion 38. The occluder 42 prevents fluid passage through the second distal portion 38 and to one of the bifurcated branches of the native bifurcation. The stent-graft 30 is adapted for placement of the stent bifurcation 44 adjacent the native bifurcation.
Fig. 2B is a detail view of the bifurcated stent 32 illustrated in Fig. 2A.
The bifurcated stent 32 has a radially compressed configuration for introduction into a lumen, and a radially expanded configuration for deployment within the lumen.
In other words, the bifurcated stent 32 is compressed radially inwards and is delivered by a catheter to the site where it is required through the patient's skin, or by a "cut down"
io technique in which the blood vessel concerned is exposed by minor surgical means.
When the stent 32 is positioned at the correct location, the stent 32 is caused or allowed to re-expand to a predetermined diameter in the vessel.
Fig. 2C is a detail view of the graft lining or covering 40 illustrated in Fig.
2A. The graft lining or covering 40 may be attached to an inside surface of the is bifurcated stent 32, functioning as a lining. Alternatively, the graft lining or covering 40 may be attached to an outside surface of the bifurcated stent 32 (as illustrated in Fig. 2A), functioning as a covering.
Fig. 2D is a detail view of one form of occluder useful in combination with stent graft 30. Specifically shown is an occluder device 42 comprising a closed, straight zo stent-graft, typically adapted for endolunninal delivery into the second distal portion 38 of the bifurcated stent 32 after the stent-graft 30 has been deployed and expanded.
Similar to the bifurcated stent 32, occluder device 42 has a radially compressed configuration for introduction into a lumen, and a radially expanded configuration for deployment within the lumen. Occluder device 42 includes a stent 43 and a graft 44, 25 either lining or covering part or all of stent 43 (as illustrated in Fig. 2A and 2D). Graft 43, however, is closed at one end to occlude fluid flow through the occluder device 42 and thus through the second distal portion 38 of the stent-graft 30.
In use, stent-graft 30 is juxtaposed or extends across a bifurcation in an artery or vein. Bifurcated stent 32 is deployed such that stent bifurcation 44 is placed 30 near or adjacent the native vessel bifurcation. First distal portion 36 extends into one of the bifurcated branches of the native bifurcation, while the second distal portion 38 extends toward and into the other bifurcated branch of the native bifurcation.
After stent-graft 30 has been deployed and expanded, occluder device 42 is placed in the second distal portion 38 of the bifurcated stent 32, so that graft 43 defines a closed 35 fluid passage, by which occluder device 42 prevents fluid from flowing through second distal portion 38 of bifurcated stent 32. Such a configuration results in a fluid passage that extends from proximal portion 34 of bifurcated stent 32 to first distal portion 36 of bifurcated stent 32. In other words, blood flows through the stent-graft 30 to the bifurcated vessel branch of the native bifurcation that contains the first distal portion 36, while blood is prevented from flowing through stent-graft 30 to the other bifurcated branch of the native bifurcation that contains second distal portion 38.
Accordingly, second distal portion 38 of stent 34 functions not as a fluid passageway, but as a structural member. The relationship among the first distal portion 36, the stent bifurcation 44, and the second distal portion 38, allows stent-graft 30 to straddle or span the native vessel bifurcation when deployed, placing the stent io bifurcation 44 adjacent the native vessel bifurcation. Such a configuration tends to resist distal migration. Preferably, contact between the stent bifurcation 44 and the native vessel bifurcation prevents the stent-graft 30 from working its way down away from its originally deployed position.
Referring to Figs 3A-3C, there is shown a stent-graft 50 adapted for is placement at a native vessel bifurcation. Stent-graft 50 includes a straight bifurcated stent-graft 52 and a tapered stent-graft 54. Straight bifurcated stent-graft 52 includes a proximal portion 56 adapted for placement in an unbifurcated region of the native bifurcation, and two distal portions 58 and 60. First distal portion 58 is adapted to extend from the unbifurcated region of the native bifurcation into one of the bifurcated 20 branches of the native bifurcation. Second bifurcation 60 extends toward and into the other bifurcated branch of the native bifurcation. A graft lining or covering 62 (graft covering 62 is represented in Fig. 3B) extends from proximal portion 56 of straight bifurcated stent-graft 52 to distal portions 58 and 60 of straight bifurcated stent-graft 52. Tapered stent-graft 54 includes a proximal tapered portion 64 and a distal portion 25 66. Distal portion 66 is adapted for placement, after the straight stent-graft 52 has been deployed and expanded, in proximal portion 56 and first distal portion 58 of straight bifurcated stent-graft 52. A graft lining or covering 68 (graft covering 68 is represented in Fig. 3A) extends from proximal portion 64 of the tapered stent-graft 54 to distal portion 66 of tapered stent-graft 54. Tapered stent-graft 54 defines a closed 30 fluid passage to first distal portion 58 of straight bifurcated stent-graft 52, and is closed to fluid passage into second distal portion 60 of straight bifurcated stent-graft 52.
Figs. 3B and 3C are detail views of the straight bifurcated stent-graft 52 and the tapered stent-graft 54, respectively, illustrated in Fig. 3A. Both stent-grafts 52 and 54 have a radially compressed configuration for introduction into a lumen, and a 35 radially expanded configuration for deployment within the lumen. In other words, the stent-grafts 52 and 54 are compressed radially inwards and are delivered by a catheter to the site where it is required through the patient's skin, or by a "cut down" technique in which the blood vessel concerned is exposed by minor surgical means. When the stent-grafts 52 and 54 are positioned at the correct location, the stent-grafts 52 and 54 are caused or allowed to re-expand to a predetermined diameter in the vessel.
Graft linings or coverings 62 and 68 may be attached to an inside surface of each respective stent 52 and 54, functioning as linings. Alternatively, graft linings or coverings 62 and 68 may be attached to an outside surface of each respective stent 52 and 54 (as illustrated in Figs. 3A - 3B), functioning as a covering.
In use, the stent-graft 50 illustrated in Fig. 3A is juxtaposed or extends io across a bifurcation in an artery or vein. The straight bifurcated stent-graft 52 is deployed such that the stent bifurcation 70 is placed near or adjacent the native vessel bifurcation. The first distal portion 58 extends into one of the bifurcated branches of the native bifurcation, while the second distal portion 60 extends into the other bifurcated branch of the native bifurcation. The tapered stent-graft 54 is positioned such that the distal portion 66 is placed in proximal portion 56 and in first distal portion 58 of straight bifurcated stent-graft 52. Graft lining or covering 68 of tapered stent-graft 54 defines a fluid passage that extends from proximal portion 56 of the straight bifurcated stent-graft 52 to first distal portion 58 of the straight bifurcated stent-graft 52. In other words, blood flows through the stent graft 50 exclusively to the bifurcated zo vessel branch of the native bifurcation that contains the first distal portion 58, while blood is prevented from flowing through the stent-graft 50 to the other bifurcated branch of the native bifurcation that contains second distal portion 60.
Accordingly, second distal portion 60 functions not as a fluid passageway, but as a structural member. The relationship among the first distal portion 58, the stent bifurcation 70, and the second distal portion 60, allows the stent-graft 50 to straddle or span the native vessel bifurcation when deployed, placing the stent bifurcation 70 adjacent the native vessel bifurcation to prevent distal migration of the device. Contact between the stent bifurcation 70 and the native vessel bifurcation may prevent stent-graft 50 from working its way down away from its originally deployed position.
While certain embodiments of the invention have been shown and described herein, it will be understood that such embodiments are provided by way of example only. Other embodiments may be devised by those skilled in the art utilizing the essential novelty of the invention as disclosed herein. It is intended that the appended claims be construed to include all such embodiments, whether or not disclosed herein.
