HANDLE FOR MEDICAL DEVICE DEPLOYMENT

摘要

A delivery system (100) for endoluminal delivery of an expandable device comprising a catheter having a proximal end and an opposite distal end configured to support an expandable device, a primary sheath having a delivery position in which the primary sheath constrains the expandable device toward a collapsed configuration suitable for endoluminal delivery, and a handle (400) having an actuator (420) for axially displacing the primary sheath from the delivery position, wherein the handle includes a knob (520) for operating one or more functions of the handle which is initially hidden to prevent use by a user and then revealed as a result of displacement of the primary sheath from delivery position so as to allow subsequent actuation of the knob by the user.
