Abstract

A clip device for hemostasis includes an introducing tube (outer sheath) insertable into a body cavity. An operating wire is slidably inserted into a n inner sheath, which in turn is separately advanceable and retractable within the outer sheath (introducing tube). The operating wire has a distal end portion and a retainer attached to the distal end portion of the operating wire. The clip device further includes a clip having a proximal end portion and at least three arm portions extending from the proximal end portion and provided with a tendency to open. A first retainer is attached to the distal end of the clip and is matingly received by a second retainer provided on th e operating wire. A clip sliding ring is provided for closing the arm portions of the clip. Methods for delivering the clip and for causing hemostasis are also provided.

Claims (9)

1. A haemostatic clip delivery system for use in endoscopic medical procedures comprising:
a) a delivery apparatus comprising an operating wire, an inner sheath, an outer sheath and a handle, the operating were being slidably disposed within the inner sheath, and the inner sheath being slidably disposed within the outer sheath;
and b) a haemostatic clip comprising a first retainer, a plurality of arms extending distally from the first retainer, and a sliding ring disposed about the plurality of arms, said arms being formed of a resilient material and shaped so that the arm tend to be spaced apart from each other, said sliding ring being configured to engage and close said arms together, wherein the handle includes a flushing port that is in fluid communication with an interior volume of the delivery apparatus, and wherein the flushing port is in fluid communication with a cavity between the inner sheath and the outer sheath, the flushing port being configured to permit the ingress or egress of fluid from near the clip device.
2. The haemostatic clip delivery system according to claim 1, wherein the flushing pork comprises a standard luer fitting.
3. The haemostatic clip delivery system according to any of the preceding claims, wherein delivery apparatus further comprises a second retainer attached to the operating wire, the second retainer being configured to engage the first retainer of the haemostatic clip so as to temporarily secure the haemostatic clip to the delivery apparatus prior to delivery of the haemostatic dip to a target site.
4. The haemostatic clip delivery system according to claim 3, wherein the sliding ring is configured to enclose the first retainer and the second retainer prior to delivery of the haemostatic clip try the target site, the sliding ring preventing the fast retainer from disengaging from the second retainer, and wherein the sliding ring is movable to a second position to permit the first retainer to disengage from the second retainer when said haemostatic clip has been delivered to the target site.
5. The haemostatic clip delivery system according to claim 4, wherein the first retainer comprises a first hook and a first notch, and the second retainer comprises a second hook and a second notch, the first hook being configured to engage the second notch, and the second hook being configured to engage the first notch.
6. The haemostatic clip delivery system according to claim 5, wherein the first retainer and the second retainer each have a generally circular cross-section, the first hook and the second hook each have a semi-circular cross-section, and the first notch and the second notch each have a semi-circular cross-section, the cross-sectional area of the first hook and the second hook being greater than that of the first and the second notch.
7. The haemostatic clip delivery system according to claim 3, wherein the sliding ring comprises a proximal portion and a distal portion, the proximal portion having a first tubular cross-section defining an interior surface that is configured to slidably engage an exterior surface of the first retainer and an exterior surface of the second retainer, and the distal portion having a second tubular cross-section that is configured to slidably engage an outer surface of each of said arms, the second tubular cross-section being smaller than the first tubular cross-section to prevent said sliding ring from being removed from the proximal end of the clip device.
8. The haemostatic clip delivery system according to any of the preceding claim, wherein the distal end of each of said arms comprises an inwardly bent tip portion.
9. The haemostatic clip delivery system according is any of the preceding claims, wherein said clip device comprises three equally spaced arms, each of said arms being curved along a portion between the distal end and the proximal end.
