Patent ID: 8535366

Claim:
A stent deployment device for allowing a user to deploy a stent in an anatomical lumen of a patient, the stent deployment device comprising: a support member configured to abut against a palm of a hand of the user; a longitudinally extending outer tubular member having distal and proximal ends along a longitudinal axis, the distal end configured to receive the stent such that the stent is slidably disposed in the outer tubular member; a longitudinally extending inner tubular member having distal and proximal ends, the distal end of the inner tubular member comprising a tip, the inner tubular member coupled with the support member and at least a portion of the inner tubular member disposed within the outer tubular member such that the inner tubular member is longitudinally and axially displaceable relative to the outer tubular member; and a deployment mechanism coupled with the outer tubular member and configured to allow staged release of the stent, the deployment mechanism comprising a graspable first release member to at least partially move the outer tubular member proximally and longitudinally relative to the inner tubular member, and a graspable second release member positioned proximal to the first release member and operably connected to the first release member to move the outer tubular member proximally and longitudinally relative to the inner tubular member, wherein the first release member is slidable along the longitudinal axis and has a first flange extending transverse to the longitudinal axis, and the second release member is slidable along the longitudinal axis and has a second flange extending transverse to the longitudinal axis, and wherein the first release member and the second release member are configured to be serially retracted to provide staged release of the stent such that slidably retracting the second release member moves the first release member and the outer tubular member proximally and longitudinally relative to the inner tubular member from a first position to a second position to partially deploy the stent, and wherein subsequent sliding retraction of the first release member moves the outer tubular member proximally and longitudinally relative to the inner tubular member from the second position to a third position to fully deploy the stent.
