Patent ID: 8518098

Claim:
A device for delivering and deploying a radially expandable prosthesis, the device comprising: a proximal release mechanism comprising a proximal sheath radially disposed over a proximal portion of a prosthesis, wherein the proximal sheath is slidable proximally relative to the prosthesis to release the proximal portion of the prosthesis, the proximal release mechanism comprising a first resistance; a distal release mechanism comprising a distal sheath radially disposed over a distal portion of the prosthesis, wherein the distal sheath is slidable distally relative to the prosthesis to release the distal portion of the prosthesis, the distal release mechanism comprising a second resistance; an actuation mechanism for actuating the proximal and distal release mechanisms in a single coordinated movement; and a biasing compensator having a longitudinally-directed biasing force acting directly on at least one of the proximal sheath and the distal sheath, whereby the biasing compensator requlates the relationship between the first resistance and the second resistance.
