Best Mode For Carrying Out Invention Referring now to the drawings, the present invention will now be described in detail. Referring to Figs. 1 and 2, the intraluminal stenting graft of the present invention is indicated by the reference number 10.
The stenting graft 10 includes a collapsible tube member 12 having a first end 14 and a second end 16. An outer layer of material 18 and an inner layer of material 20 extend between said first end 14 and said second end 16. A first end wall 22 extends between the outer layer 18 and the inner layer 20 at the first end 14. A second end wall 24 extends between the outer layer 18 and the inner layer 20 at the second end 16.
As shown in Figs. 1, 2 and 4, the outer layer 18 is joined to the inner layer 20 to form a plurality of cylinders 30 that extend longitudinally between the first end 14 and the second end 16. As shown in Fig. 1, the tube member 12 can include a radially extending chamber 32 that is in communication with the plurality of cylinders 30.
In the present embodiment, the chamber 32 is positioned adjacent the first end 14. However, it should be understood that the chamber 32 can be positioned in a variety of locations along the length of the chamber.
, Wo96~l4027 ~ 2 n 1 3 1 9 PCT/USg5/14327 Referring to Fig. 1, the tube member 12 can include an opening 40 in the first end wall 22. The opening 40 can receive a fluid, such as air.
As described below, the fluid causes the collapsed tube member 12 to expand for implantation in a blood vessel. As shown in Fig. 3, a one-5 way vaive 42, such as a check valve, can be positioned in the opening 40. The valve 42 allows for the introduction of the fluid into the tube member 12. The valve prevents the escape of the fluid from the tube member 12 after introduction into the tube member. The fluid can be introduced into the tube member 12 through the valve 42 by a fluid 10 conduit 44.
Referring to Fig. 2, the outer layer 18 and the inner layer 20 are composed of a polymer material that is biocompatible. An example of such a material is polytetrafluoroethylene. The outer layer 18 is constructed of a more flexible or lighter weight material than the inner 15 layer 20. This allows the outer layer 18 to be more compliant when the tube member 12 is expanded. The inner layer 20 can be treated or coated with a material such as expanded polytetrafluoroethylene (ePTFE) to create a surface more conducive to blood flow.
As shown in Fig. 2, each of the cylinders 30 includes a centerline 20 C that extends longitudinally through the cylinder when the tube member 12 is in an expanded condition. The centerline C is a point from which two radii Rl and R2 extend. The radii Rl and R2 define an angle ,B. The angle ,B can be an obtuse angle being more than 90 and less than 180.
When the plurality of cylinders 30 are positioned adjacent one another to 25 form the tube member 12, as shown in Fig. 2, the radius R1 of one of the cylinders bisects the radius R2 of the adjacent cylinder. This arrangement causes the plurality of cylinders 30 to cooperate to maintain the tube member 12 in a stable, expanded condition for implantation in a blood vessel. It has been found that the greater compliance of the outer layer 30 18 and the greater amount of material of the outer layer 18 as compared _ to the inner layer 20 causes the angle ,~ to be less than 180. When the tube member 12 is expanded, the plurality of cylinders 30 interfere with one another to force the tube member into a round configuration as shown in Fig. 1. This provides an open pathway 46 for the flow of blood in a blood vessel.
Referring now to Figs. 5 and 6, the intraluminal stenting graft 10 of the present invention is implanted in a blood vessel 50 by manipulating the collapsed tube member 12 through the vessel to an implantation site 52. The tube member can be manipulated by the conduit 44, which is in communication with the valve 42, or by some other suitable apparatus. As shown in Fig. 6, when the stenting graft 10 is in the proper position, fluid from the conduit 44 is introduced through the opening 40 and into the chamber 32 and cylinders 30. The chamber 32 allows for an efficient distribution of fluid into the cylinders 30. As described above, the plurality of cylinders 30 and the outer and inner layers 18 and 20, respectively, cooperative to maintain the tube member 12 in a round and open configuration. After filling, the conduit 44 is removed. The stenting graft 10 allows blood flow through the pathway 46 at the site of implantation 52.
A second embodiment of the intraluminal stenting graft 10 of the present invention is shown in Fig. 7. The stenting graft 10 includes a trunk portion 60 and branch portions 62 and 64. This embodiment can be used, for example, at the bifurcation of the aorta and iliac arteries.
The trunk portion 60 can be positioned in the aorta and the branch portions 62 and 64 can be positioned in the iliac arteries. Many other configurations can be constructed depending on the application.
Referring now to Figs. 8 through 1 1, the method for manufacturing an intraluminal stenting graft according to the present invention will be described in detail. Referring to Fig. 8, a first layer of material 70, which corresponds to the inner layer 20, is placed on a flat surface such as a WO96/14027 2 2 û ~ 3 1 ~ Pcr/uss5/14327 platen 72. A bonding agent such as adhesive 76 is applied to the first layer 70 by applicators 78.
As shown in Fig. 9, a second layer of material 80, which corresponds to the outer layer 18, is placed on a shaped surface 82. The 5 shaped surface 82 includes longitudinally extending indentations 84 having, for example, partially cylindrical shapes. The indentations include a coating 86 of synthetic resin polymers and products, such as Teflon~, to prevent the second layer 80 from adhering to the shaped surface 82.
The second layer 80 is maintained on the shaped surface 82 by the use 10 of reverse pressure or vacuum created by a reversible pump P.
As shown in Fig. 10, the second layer 80 is moved to the first layer 70. The layers 70 and 80 are fixedly joined together by the adhesive 74. The layers can also be joined by a heat sealing process (not shown).
As shown in Fig. 11, the joining of the first layer 70 to the second layer 80 forms a plurality of longitudinally extending cylinders 30, as described above. A chamber 30, end walls 22 and 24 and opening 40 can also be formed in the method. The longitudinally extending ends of the joined layers can be brought together and joined by adhesive or 20 otherwise to form the cylindrical tube member 12 shown in Figs. 1 and 5.
The first layer 70 and second layer 80, as used in the method, can be constructed of a polymer material, as described above for the outer layer 18 and inner layer 20. The second layer 80 is more flexible and is 25 lighter weight than the first layer 70. The cylinders 30 that are formed as a result of the method have the same characteristics as described above concerning the centerline C, radii R1 and R2 and the angle ,~ being less than 180.
-Wo 96/14027 Pcr/USs5/14327 The present invention can be modified and changed in a variety ofways with the scope of the invention being defined by the appended claims.

Best Mode For Carrying Out Invention Referring now to the drawings, the present invention will now be described in detail. Referring to Figs. 1 and 2, the intraluminal stenting graft of the present invention is indicated by the reference number 10.
The stenting graft 10 includes a collapsible tube member 12 having a first end 14 and a second end 16. An outer layer of material 18 and an inner layer of material 20 extend between said first end 14 and said second end 16. A first end wall 22 extends between the outer layer 18 and the inner layer 20 at the first end 14. A second end wall 24 extends between the outer layer 18 and the inner layer 20 at the second end 16.
As shown in Figs. 1, 2 and 4, the outer layer 18 is joined to the inner layer 20 to form a plurality of cylinders 30 that extend longitudinally between the first end 14 and the second end 16. As shown in Fig. 1, the tube member 12 can include a radially extending chamber 32 that is in communication with the plurality of cylinders 30.
In the present embodiment, the chamber 32 is positioned adjacent the first end 14. However, it should be understood that the chamber 32 can be positioned in a variety of locations along the length of the chamber.
, Wo96~l4027 ~ 2 n 1 3 1 9 PCT/USg5/14327 Referring to Fig. 1, the tube member 12 can include an opening 40 in the first end wall 22. The opening 40 can receive a fluid, such as air.
As described below, the fluid causes the collapsed tube member 12 to expand for implantation in a blood vessel. As shown in Fig. 3, a one-5 way vaive 42, such as a check valve, can be positioned in the opening 40. The valve 42 allows for the introduction of the fluid into the tube member 12. The valve prevents the escape of the fluid from the tube member 12 after introduction into the tube member. The fluid can be introduced into the tube member 12 through the valve 42 by a fluid 10 conduit 44.
Referring to Fig. 2, the outer layer 18 and the inner layer 20 are composed of a polymer material that is biocompatible. An example of such a material is polytetrafluoroethylene. The outer layer 18 is constructed of a more flexible or lighter weight material than the inner 15 layer 20. This allows the outer layer 18 to be more compliant when the tube member 12 is expanded. The inner layer 20 can be treated or coated with a material such as expanded polytetrafluoroethylene (ePTFE) to create a surface more conducive to blood flow.
As shown in Fig. 2, each of the cylinders 30 includes a centerline 20 C that extends longitudinally through the cylinder when the tube member 12 is in an expanded condition. The centerline C is a point from which two radii Rl and R2 extend. The radii Rl and R2 define an angle ,B. The angle ,B can be an obtuse angle being more than 90 and less than 180.
When the plurality of cylinders 30 are positioned adjacent one another to 25 form the tube member 12, as shown in Fig. 2, the radius R1 of one of the cylinders bisects the radius R2 of the adjacent cylinder. This arrangement causes the plurality of cylinders 30 to cooperate to maintain the tube member 12 in a stable, expanded condition for implantation in a blood vessel. It has been found that the greater compliance of the outer layer 30 18 and the greater amount of material of the outer layer 18 as compared _ to the inner layer 20 causes the angle ,~ to be less than 180. When the tube member 12 is expanded, the plurality of cylinders 30 interfere with one another to force the tube member into a round configuration as shown in Fig. 1. This provides an open pathway 46 for the flow of blood in a blood vessel.
Referring now to Figs. 5 and 6, the intraluminal stenting graft 10 of the present invention is implanted in a blood vessel 50 by manipulating the collapsed tube member 12 through the vessel to an implantation site 52. The tube member can be manipulated by the conduit 44, which is in communication with the valve 42, or by some other suitable apparatus. As shown in Fig. 6, when the stenting graft 10 is in the proper position, fluid from the conduit 44 is introduced through the opening 40 and into the chamber 32 and cylinders 30. The chamber 32 allows for an efficient distribution of fluid into the cylinders 30. As described above, the plurality of cylinders 30 and the outer and inner layers 18 and 20, respectively, cooperative to maintain the tube member 12 in a round and open configuration. After filling, the conduit 44 is removed. The stenting graft 10 allows blood flow through the pathway 46 at the site of implantation 52.
A second embodiment of the intraluminal stenting graft 10 of the present invention is shown in Fig. 7. The stenting graft 10 includes a trunk portion 60 and branch portions 62 and 64. This embodiment can be used, for example, at the bifurcation of the aorta and iliac arteries.

Referring now to Figs. 8 through 1 1, the method for manufacturing an intraluminal stenting graft according to the present invention will be described in detail. Referring to Fig. 8, a first layer of material 70, which corresponds to the inner layer 20, is placed on a flat surface such as a WO96/14027 2 2 û ~ 3 1 ~ Pcr/uss5/14327 platen 72. A bonding agent such as adhesive 76 is applied to the first layer 70 by applicators 78.
As shown in Fig. 9, a second layer of material 80, which corresponds to the outer layer 18, is placed on a shaped surface 82. The 5 shaped surface 82 includes longitudinally extending indentations 84 having, for example, partially cylindrical shapes.
