Abstract
Disclosed is a tubular prosthesis formed by rolling a flexible sheet around a longitudinal axis. Preferably, the prosthesis is self expandable under the radially outwardly directed spring bias of the rolled sheet. Also disclosed are catheters for delivering two or more of the tubular prostheses at a site within a body lumen. Multiple prostheses may be deployed directly against a vessel wall in a single procedure, or may be deployed within a vascular graft to provide support throughout the length of the graft.
Claims23
An endobypass delivery system, comprising:
- an elongate, flexible, tubular body, having a sidewall and proximal and distal ends;
- a support cavity in the tubular body, accessible through both an end opening on the distal end of the tubular body and through a side opening in the sidewall of the tubular body;
- a first self-expanding support in the support cavity, the support having a free edge extending through the side opening;
- and
- a tubular graft attached to the free edge.
An intravascular graft delivery catheter, comprising:
- an elongate, flexible tubular body;
- a self-expanding graft support, removably positioned within the tubular body, wherein said self-expanding graft support comprises a flexible sheet, rolled into a generally cylindrical configuration and a distal portion of the tubular body is provided with an axially extending slot, and a free end of the rolled sheet is connected through the slot to the graft;
- and
- an elongate, flexible tubular graft, secured to the support and extending proximally along the tubular body.
