1. A method of treating a patient, comprising:
- providing a tubular implant and a delivery catheter adapted to engage with the tubular implant;
engaging the tubular implant with the delivery catheter;
inserting at least a portion of the delivery catheter into a body of the patient; and
disengaging the tubular implant and the delivery catheter, thereby implanting the tubular implant within the body of the patient,wherein the implant is disengaged after fewer than 24 hours have elapsed from the engagement of the tubular implant with the catheter.

Abstract
Delivery systems for a polymeric tubular implant, kits that include such delivery systems, and methods of treating patients by implanting tubular implants using the delivery systems. The delivery systems include an inner shaft, an expandable member slidably disposed about the inner shaft and configured to receive the tubular implant, and a tubular outer shaft disposed about the inner shaft.

13. A method of treating a patient, comprising the steps of:
-
providing a tubular implant having a first diameter when in an unstressed configuration and a second diameter less than the first diameter when in a compressed configuration; providing a delivery device, comprising; an inner shaft comprising a distal end and a proximal end, wherein at least a portion of said inner shaft has a diameter less than the first diameter of the tubular implant; a first expandable member slidably disposed about said inner shaft, said first expandable member comprising an open distal end having a cross-sectional dimension greater than the first diameter of the tubular implant and a proximal end having a cross-sectional dimension less than the first diameter of the tubular implant; and a tubular outer shaft slidably disposed about said inner shaft, said tubular outer shaft having a distal end and a proximal end and an inner diameter less than the first diameter of the tubular implant; advancing the tubular implant over the distal end of the inner shaft and the cushion; advancing first expandable member distally so that at least a portion of the tubular implant is located within the distal end of the first expandable member; advancing the distal end of the tubular outer shaft over the first expandable member and the tubular implant, thereby compressing the tubular implant and loading it between the inner shaft and the outer shaft; withdrawing the first flexible member such that no portion of the tubular implant is located within the first flexible member; inserting the distal end of the inner shaft including the first expandable member and the tubular implant into a patient; and withdrawing the distal end of the outer shaft to expose the cylindrical implant, thereby permitting the cylindrical implant to relax away from the inner cylindrical member.
