Percutaneously deliverable intravascular occlusion prosthesis
First Claim
Patent Images
1. An intravascular prosthesis comprising:
- a lining rolled upon itself in a plurality of turns around a longitudinal axis so that it is introducible into a vascular lumen surrounded by a vascular wall;
an inflatable channel associated with said lining and being rolled upon itself around said longitudinal axis, said channel including a filling port for the introduction of fluid into said channel for the inflation thereof, said lining and said channel having the capability of unrolling when said channel is inflated so that the lining may engage the vascular wall to provide support therefor; and
an occlusion member connected to said lining and positioned so that when the lining is unrolled, said member extends substantially transversely across the interior of said unrolled lining to prevent blood from passing through the prosthesis.

Abstract
An intravascular prosthesis comprises a lining rolled upon itself around an axis so that it is introducible into a vascular lumen. An inflatable channel is included for unrolling the lining when the prosthesis is positioned within the lumen so that the lining may engage the vascular wall to provide support therefor. An occlusion member is provided for occluding the vascular lumen, when the lining is unrolled, by preventing blood from passing through the prosthesis.
