First Claim
Patent Images
1. A controlled release and recapture prosthetic deployment device comprising:
- a handle including a handle body;
a tubular sheath;
a sheath-attached puller extending slidably through the handle body and fixedly attached to the sheath; and
an elongate stent-holder member fixedly extending through and distally out from the handle body, and further extending through a longitudinal lumen of the sheath, which sheath is slidable relative to the stent-holder member;
wherein the handle comprises;
a retaining member in the handle body, where the retaining member is biased toward a distal device end;
a keeper member in the handle body, where the keeper body releasably engages the sheath-attached puller and is also biased toward a distal device end; and
a first trigger member,pivotable relative to the handle body,disposed in mechanical communication with the advancement member, andconfigured to move the retaining member and the sheath-attached puller proximally when the trigger member is pivoted in a first direction.

Abstract
A delivery device for deploying and resheathing an expandable prosthesis such as a stent. The delivery device includes a movable outer sheath and a fixed pusher/holder member that are configured for the sheath to retract in a proximal direction to release and/or to extend distally to resheath the stent. The device includes a spring-tensioned anti-backlash mechanism to accommodate any backlash elongation and/or compression of the pusher/holder member and sheath.
