Abstract
An endoluminal prosthesis system includes a tubular graft having a pocket on the exterior of the graft. The graft further includes a wire extending within a lumen of the graft, with the wire extending through the passageway and into the pocket. An extension prosthesis can be inserted over the wire and into engagement with the pocket and the passageway, where the extension prosthesis can be sealed with the pocket and the passageway to seal the otherwise unused passageway in the graft.
Claims20
A prosthesis system, comprising:
- a graft having a tubular body with a proximal and distal end, a lumen between the proximal and distal ends, and a surface comprising a first biocompatible material;
- at least one passageway extending through a sidewall of the graft;
- a pocket disposed on an exterior surface of the graft, the pocket having a cavity and an opening open to an exterior of the graft;
- and
- a wire extending through the lumen of the graft and through the passageway out of the lumen and into the pocket cavity.
A system for sealing an unused passageway in a graft, the system comprising:
- an expandable tubular graft having proximal and distal ends and a lumen between the proximal and distal ends;
- at least one passageway extending through a sidewall of the tubular graft;
- a pocket attached to an external surface of the tubular graft;
- a wire extending through the lumen and through the passageway out of the lumen and into the pocket;
- and
- an expandable tubular branch extension disposed over the wire between the pocket and the passageway.
A method for sealing an unused passageway in a tubular prosthesis, the method comprising:
- delivering a tubular graft to a body vessel, the tubular graft having proximal and distal ends and a lumen between the proximal and distal ends, the graft further having a passageway in a sidewall thereof, a pocket disposed on an exterior surface of the graft, the pocket having a cavity, and a wire extending through the lumen of the graft and out of the lumen through the passageway and into the pocket cavity;
- delivering an expandable tubular graft extension along the wire toward the pocket;
- engaging the tubular graft extension with the pocket and the passageway;
- expanding the tubular graft extension;
- and
- sealing the tubular graft extension to the pocket and the passageway.
