US Patent 10555824 Stent device delivery system with inwardly tapering stent bed

A stent device delivery system and method of making. The stent device delivery system includes a stent device, an outer sheath overlaying the stent device in a radially compact, delivery configuration of the stent device, and an inner catheter extending axially and radially within a lumen of the stent device. The inner catheter provides a stent bed upon which the stent device is located so that a radially inner surface of the stent device engages a radially outer surface of the stent bed. The stent bed may define an inwardly tapering profile, narrowing in radius from a distal portion of the stent device to a proximal portion of the stent device.
