PROSTHESIS DEPLOYMENT SYSTEM FOR OPEN SURGICAL REPAIR
First Claim
1. A deployment system for repair of a body vessel comprising:
- a prosthesis having a first prosthesis end and a second prosthesis end, and being radially movable between a compressed configuration and an expanded configuration;
a retainer sheath fitted at least partially over a segment of the prosthesis to retain said segment in the compressed configuration, the retainer sheath comprising a tubular body, a first sheath end, a second sheath end, and a lumen extending therethrough to receive the prosthesis;
a splitting member having an internal portion disposed between a luminal wall of the retainer sheath and the prosthesis, and an external portion disposed external to the retainer sheath, wherein the splitting member is operable to split a wall of the retainer sheath along a direction toward a middle of the prosthesis away from at least one of the first and second sheath ends upon retraction of the external portion of the splitting member, wherein in response to being split by the splitting member, the retainer sheath has a split configuration and the corresponding prosthesis end is allowed to move to the expanded configuration for engagement with a body vessel wall.

Abstract
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.

17. A method of interconnecting a first vessel portion and a second vessel portion of a transected body vessel, comprising:
-
introducing a first end of a prosthesis retained in a compressed configuration by a retainer sheath in a first vessel portion, wherein a splitting member is associated with the retainer sheath and is operable to split a wall of the retainer sheath; and retracting a portion of the splitting member in a direction away from a middle of the prosthesis to split the retainer sheath from an outer end thereof and toward the middle such that the first end of the prosthesis is permitted to expand to an expanded configuration for engagement with a vessel wall of the first vessel portion. - View Dependent Claims (18, 19, 20)
