International Classification:

A61F002/06

US Classification:

623001110, 604524000

Abstract:

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

Abstract:

A delivery system () for implanting a medical device () such as a venous valve into the vasculature of a patient. The delivery system includes a delivery catheter () having a device-containing portion () adjacent to the distal end () thereof, and an inner member () extending through the catheter and beyond the distal end thereof, to an atraumatic distal tip portion () forward of the catheter distal end. The inner member extends through the medical device in the device-containing region, includes a proximal portion () with a sufficiently large diameter to prevent longitudinal movement of the device as the catheter is retracted during deployment, and centers the device upon release from the distal catheter end during deployment. The inner member is preferably radiolucent underlying the device for contrast with radiopaque markers () of the device. The inner member preferably includes a flat portion () extending from the device-containing portion to the proximal end () to form a passageway or lumen () with the delivery catheter to transmit hydrating fluid to a device such as a valve containing lyophilized tissue requiring hydration immediately prior to patient implantation.
