Distal Capture Device for a Self-Expanding Stent

摘要

A delivery system including a distal capture device that has a sleeve with a passageway defined axially therethrough and one or more elastically deformable sections. Each of the one or more elastically deformable sections has a free terminating end and an opposite end mounted to the distal end of the sleeve. The elastically deformable sections transition between: (i) a fully expanded state in which the elastically deformable section is distally biased in a direction away from the sleeve; and (ii) a retracted state in which the free terminating end of each of the elastically deformable sections is proximally deflected backwards over itself in a direction toward the proximal end of the sleeve.

1. A delivery system comprising:
a distal capture device comprising:
a sleeve having a proximal end, an opposite distal end and a passageway defined axially therethrough; andat least one elastically deformable section, each of the at least one elastically deformable section has a free terminating end and an opposite end mounted to the distal end of the sleeve; wherein the at least one elastically deformable section transitions between: (i) a fully expanded state in which the at least one elastically deformable section is distally biased in a direction away from the sleeve; and (ii) a retracted state in which the free terminating end of each of the at least one elastically deformable section is proximally deflected backwards over itself in a direction toward the proximal end of the sleeve.
