Abstract
A system for endoluminally delivering and deploying a prosthesis includes a prosthesis comprising a self-expanding stent and a cover for retaining at least a portion of the self-expanding stent. The stent is biased into contact with an inner surface of the cover. The inner surface has a hardness that is equal to or greater than the hardness of the stent. Additional aspects of the invention are disclosed and include a method of manufacturing an endoluminal prosthesis delivery and deployment system.
Claims10
A system for endoluminally delivering and deploying a prosthesis, the system comprising:
- a prosthesis having an end portion and a body portion, the end portion including a self-expanding stent having a hardness;
- and
- a cover for maintaining at least a portion of the stent in a compressed state until deployment, the cover having a generally tubular cavity with an inner surface, wherein the stent is biased into contact with the inner surface of the cover, the inner surface having a hardness that is equal to or greater than the hardness of the stent, wherein the inner surface comprises a ceramic material.
A system for endoluminally delivering and deploying a prosthesis, the system comprising:
- a prosthesis having an end portion and a body portion, the end portion including a self-expanding stent having a hardness;
- and
- a cover for maintaining at least a portion of the stent in a compressed state until deployment, the cover having a generally tubular cavity with an inner surface, wherein the stent is biased into contact with the inner surface of the cover, the inner surface having a hardness that is equal to or greater than the hardness of the stent, wherein the cover comprises a plastic body with a ceramic inner surface.
A method of manufacturing an endoluminal prosthesis delivery and deployment system, the method comprising the steps of:
- providing a prosthesis having a proximal end and a distal end, at least one of the proximal and distal ends including a self-expanding stent having a hardness;
- providing a cover having a cavity defining an inner surface, the inner surface having a hardness that is equal to or greater than the hardness of the stent;
- and retaining at least a portion of the stent within the cavity so that the stent is biased into contact with the inner surface, wherein the cover providing step comprises providing a ceramic inner surface.
