PROSTHESIS DEPLOYMENT SYSTEM FOR OPEN SURGICAL REPAIR

摘要

A deployment system for open surgical repair of a body vessel is provided. The system includes a prosthesis retained in a compressed configuration by a retainer sheath. A splitting member can include a portion disposed internally within the retainer sheath and a portion accessible from at least one of the outer ends of the retainer sheath. Retraction of the accessible portion toward a middle of the prosthesis can split the wall of the retainer sheath to allow for expansion of a segment of the prosthesis for engagement with a first portion of the body vessel. Another segment of the prosthesis is expanded for engagement with a second portion in order for the prosthesis to interconnect the first and second portions of the body vessel. A barrier segment may be disposed within the retainer sheath between the splitting member and the prosthesis.
