A heart valve delivery system may include a handle, a shaft having a proximal end fixedly connected to the handle and extending distally along an axis away from the handle to a free end, and a tube surrounding the shaft. The tube may have a proximal end connected to the handle and extend distally along the axis away from the handle to a distal end. The tube may be axially movable relative to the shaft and the handle between a fully extended position at which the tube extends distally farther than the shaft, and a fully retracted position at which the shaft extends distally farther than the tube. The system may include an inserter for guiding insertion of the tube. In addition or in alternative to the inserter, the system may include a funnel for loading the prosthetic valve into the tube.

Distally loaded sheath and loading funnel

An implantable delivery system has an inner shaft () with a device-carrying region () and an outer shaft () surrounding the inner shaft. A sheath () at a distal end of the outer shaft covers the device-carrying region when the outer shaft is in an advanced position. A sleeve () surrounding the outer shaft is in proximity to the sheath when the sleeve is in an advanced position. After insertion, the sleeve is retracted to increase flexibility of the distal end of the device. A handle () includes a control element for retracting the outer shaft and sheath relative to the inner shaft to release the implantable device. The sleeve may be fixed to the body of the handle when the sleeve is retracted. Engagement between the sleeve and an introducer at the insertion site can stabilize the handle and inner shaft against movement relative to the patient during retraction of the outer shaft.
