Medical device delivery system
First Claim
1. A medical device delivery system comprising:
- a delivery catheter having an inner lumen extending from a proximal end to a distal end and having a device-containing region adjacent the distal end, the delivery catheter comprising an inner tube, a coil fitted to the inner tube, and an outer tube disposed around the coil and the inner tube;
an inner member extendable through the delivery catheter from the proximal end to and through the device-containing region to and beyond the distal end of the delivery catheter, the inner member having a distal tip portion, a proximal portion, and an intermediate portion disposed between the distal tip portion and the proximal portion; and
wherein the proximal portion has a distal end that is sized approximating the inner lumen of the delivery catheter at least through the device-containing region and that engages a medical device when the medical device is positioned around the intermediate portion and in the device-containing region of the delivery catheter.

Abstract
A delivery system (10) for implanting a medical device (30) such as a venous valve into the vasculature of a patient. The delivery system includes a delivery catheter (11) having a device-containing portion (15) adjacent to the distal end (14) thereof, and an inner member (16) extending through the catheter and beyond the distal end thereof, to an atraumatic distal tip portion (17) forward of the catheter distal end. Delivery catheter (11) includes inner tube (122), flat wire coil (123) compression fitted therearound, and outer tube (112) mechanically connected to roughened outer surface (126) of the inner tube through the spacing of the coil. Delivery catheter (11) can be provided with a window (184) to allow fluoroscopic visualization of a stent valve within the delivery system.
