Vascular and intestinal occlusion

摘要

A device for occluding a conduit includes first and second members, each with first and second ends. The second ends are connected by a hinge. The first ends interlock to close the device about the conduit. The members are shaped such that they can occlude the conduit without causing the development of damaged or necrotic tissue. If desired, a flexible cover can be provided and the first and second members can be disposed within the cover. If such a cover is used, it will contact the conduit in order to cushion the contact between the members and the conduit, minimize the tendency of the conduit to bleed, and increase traction relative to the conduit. The invention also includes methods for using the device to occlude a conduit.

主权项

1. A device for occluding a conduit, comprising:
a first member having first and second ends adapted to extend from one side of the conduit to the other and to contact the conduit on a selected side thereof; a second member having first and second ends adapted to extend from one side of the conduit to the other and to contact the conduit on the other side thereof; the first and second ends of the first and second members lying in a first plane; a hinge that connects the second ends of the first and second members, the hinge being generally U-shaped and constituting an integral extension of the second ends of the first and second members to establish a structure that is closed at the second ends of the first and second members and open at the first ends of the first and second members when the first and second members are in a first, open position; the first and second members being generally arc-shaped when viewed from above and lying in a second plane that is generally orthogonal to the first plane; the first ends of the first and second members being movable in the first plane from the first, open position in which the conduit can fit therebetween to a second, closed position in which the first and second members are disposed generally parallel with each other and being disposed sufficiently close to each other to compress the conduit between them without causing the development of damaged or necrotic tissue; those portions of the first and second members that contact the conduit being configured to minimize stress concentrations in the conduit; a flexible cover for the first and second members, the cover being biocompatible with the conduit and providing traction relative to the conduit; and wherein the cover does not extend beyond the first ends of the first and second members such that the device, when provided with the flexible cover, remains open at the first ends of the first and second members when the first and second members are in the first, open position.
