SELF-RESTRAINING ENDOLUMINAL PROSTHESIS
First Claim
Patent Images
1. A self-restraining, self-expanding stent, comprising;
- an elongate, unitarily-formed tubular body having a longitudinal axis and comprising a plurality of elastic expansile elements, the tubular body configured to be collapsible radially inwardly into a compacted configuration, the elastic expansile elements urging the tubular body to expand radially outwardly toward an expanded configuration; and
first and second latch members extending from the body, the latch members configured to engage one another when the body is in the compacted configuration so as to restrain a portion of body from expanding to the expanded configuration, the first latch member having an axis and having a generally hook-shaped tip adapted to engage the second latch member;
wherein the first latch member is twisted about its axis while engaged with the second latch member.

Abstract
A self-expanding, self-restraining endoluminal prosthesis is configured to be compressible into a collapsed state, and restrained in the collapsed state by structures integrated with the stent, and without the use of external structure. Such restraining structures engage one another to hold the prosthesis in the collapsed state. Expansile elements of the prosthesis urge the prosthesis to automatically expand once released from the collapsed state. Thus, once the restraining structures, which hold the prosthesis in the collapsed state, are disengaged, the prosthesis automatically expands to a deployed state.
