BLOOD PERFUSION DEVICE DELIVERY SYSTEM

摘要

A delivery system deploys a prosthesis for open surgical repair of a body vessel. The system includes a sleeve to retain segments of a prosthesis in a compressed configuration and retraction members. The sleeve has outer segments associated with each end of the prosthesis. Retraction of the retraction members removes the outer segments of the sleeve from the prosthesis outer ends to allow for expansion of the outer ends of the prosthesis in an outside-in direction. The system can include a handle and an actuation member movably attached to the handle. The actuation member is coupled to the sleeve outer segments so that movement of the actuation member corresponds to removal of the sleeve. The system can include elements to retain the sleeve outer segments to the actuation member and to redirect the retraction members to a direction different from the axis of the prosthesis.

主权项

1. A method of open surgical repair of a lacerated or transected body vessel to obtain fluid stability while maintaining fluid flow through the body vessel, comprising:
inserting a first outer end of a prosthesis into a first vessel portion of the body vessel, wherein the prosthesis comprises a support structure and a graft body, the first outer end of the prosthesis being retained in a compressed configuration with a first sleeve portion, the first outer end being self-expandable and the first sleeve portion being dissolvable; inserting a second outer end of the prosthesis into a second vessel portion of the body vessel, wherein the second outer end of the prosthesis is retained in a compressed configuration with a second sleeve portion, the second outer end being self-expandable and the second sleeve portion being dissolvable; and dissolving the first and second sleeve portions while the first and second outer ends of the prosthesis are within the first and second vessel portions, the first and second sleeve portions thereby weakening retention of the first and second outer ends and the first and second outer ends radially expanding to engage the first and second vessel portions, the prosthesis comprising a longitudinal length sufficient to bridge and seal the laceration or bridge and interconnect the gap between the transection.
