Single handed deployment handle

摘要

The present invention is directed to an improved delivery system to deliver and deploy a prosthesis in a body lumen, and methods of use thereof. The improved delivery system allows for operation of the delivery system with one hand while maintaining accuracy in delivery and deployment of the prosthesis. An exemplary embodiment of the delivery system includes a first sheath control on a housing so as to be accessible from the exterior of the housing, wherein the first sheath control is operatively engaged with the sheath and controls movement of the sheath axially proximally with respect to the housing, thereby releasing at least a portion of the prosthesis.

主权项

1. A delivery system for delivering a prosthesis to a location in a body, the delivery system comprising:
a housing having a longitudinal axis; a sheath extending from within the housing; a first sheath control coupled to the housing and accessible from the exterior of the housing, wherein the first sheath control is configured to operatively engage with the sheath, wherein a first actuation of the first sheath control causes the sheath to move axially in a proximal direction with respect to the first sheath control to release at least a portion of the prosthesis if the first sheath control is engaged with the sheath; a sheath engagement control coupled to the housing and accessible from the exterior of the housing, wherein the sheath engagement control selectively engages and disengages the first sheath control from the sheath; and a second sheath control coupled to and movable axially with respect to the housing, wherein the second sheath control is fixed to the sheath such that the sheath moves axially with the second sheath control to release or retract at least a portion of the prosthesis with the sheath engagement control actuated such that the first sheath control is disengaged from the sheath.
