STENT DEVICE DELIVERY SYSTEM WITH INWARDLY TAPERING STENT BED
First Claim
1. A stent device delivery system, comprising:
- a stent device;
an outer sheath overlaying the stent device in a radially compact, delivery configuration of the stent device, the outer sheath retractable from a distal end of the stent device to a proximal end of the stent device to allow for radial expansion of the stent device to a deployed configuration; and
an inner catheter extending axially and radially within a lumen of the stent device and providing 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, wherein the stent bed defines an inwardly tapering profile, narrowing in radius from a distal portion of the stent device to a proximal portion of the stent device.

Abstract
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.

16. A method of making a stent device delivery system, comprising:
-
loading a stent device into a sleeve of polymeric material, the sleeve providing an outer sheath of the stent device delivery system that is retractable relative to the stent device to allow the stent device to radially expand to a deployed configuration; positioning an inner catheter radially and axially within a lumen of the stent device, the inner catheter presenting a stent bed with an inwardly tapering profile for the stent device to be located upon; and cold drawing the sleeve with the stent device loaded therein to reduce the diameter of the sleeve and to transition the stent device from a radially expanded configuration into a radially reduced delivery configuration, thereby bringing into engagement a radially inner surface of the stent device and a radially outer surface of the stent bed. - View Dependent Claims (17, 18, 19, 20)
