Abstract
A delivery device for an implantable medical device may include an inner shaft configured to retain the implantable medical device at its distal end, an outer shaft slidably disposed about the inner shaft, and a locking hub affixed to the outer shaft. The locking hub may include a housing, a piston element in the housing, an actuator operatively coupled to the piston element, and a clamping gasket made of a compressible material and disposed in the housing. The actuator may be movable relative to the housing between unlocked and locked conditions. The clamping gasket may have a lumen defining a first diameter with the actuator in the unlocked condition and a second diameter with the actuator in the locked condition, the second diameter being less than the first diameter. The outer shaft and the locking hub may be fixed to the inner shaft with the actuator in the locked condition.
