Emergency vascular repair prosthesis

摘要

A prosthesis system for repair of a transected body vessel is provided. The system can include first and second prostheses each including a tubular graft body and a support structure. Each prosthesis can be expandable between a compressed and an expanded configuration. In the expanded configuration, outer surfaces of the first and second prostheses can engage walls of the body vessel. The system can include a sleeve member formable into a tubular body. The first and second prostheses can be coupled to one another at a joint to form a coupled prosthesis. The sleeve member can receive the coupled prosthesis and cover the joint to inhibit leakage therefrom. The prosthesis system can connect first and second portions of the body vessel to permit blood flow therethrough. The sleeve member can be discrete to the coupled prosthesis or can have one end fixedly attached to the coupled prosthesis.

主权项

1. An emergency open surgical method of repairing a lacerated or transected blood vessel to obtain hemostasis while maintaining blood perfusion by interconnecting a first vessel portion and a second vessel portion of the lacerated or transected vessel, the method comprising:
gaining open surgical access to the lacerated or transected vessel; introducing a first end of a first prosthesis in a compressed configuration into the first vessel portion such that a second end of the first prosthesis is exposed external to the first vessel portion; expanding the first prosthesis to an expanded configuration such that the first end of the first prosthesis engages a wall of the first vessel portion; introducing a first end of a second prosthesis in a compressed configuration into the second vessel portion such that a second end of the second prosthesis is exposed external to the second vessel portion; expanding the second prosthesis to an expanded configuration such that the first end of the second prosthesis engages a wall of the second vessel portion; coupling the second end of each of the first and second prostheses together at a joint external to the first and second vessel portions to form a coupled prosthesis; covering the joint of the coupled prosthesis with a sleeve member to inhibit leakage from the joint of the coupled prosthesis; and wherein the sleeve member further comprises a first end fixedly attached to one of the first and second prostheses and a second free end, wherein the covering step further comprises moving the second free end of the sleeve member to the other of the first and second prostheses to cover the joint of the coupled prosthesis.
