摘要： A system for implanting a catheter in a urethra. The system includes a catheter having a valve disposed at a distal portion of the catheter. The valve may be operable in response to an external magnetic field. The system also includes a tool having a tip member extending into an opening at the distal portion of the catheter to couple the tool to the catheter, the system also includes an element extending from the tool. The catheter has an internal path that provides a conduit for the element to be extended through the valve to engage a proximal portion of the catheter. The tool is adapted use the element to stress the catheter and stiffen the catheter along the length of the catheter. Stiffening the catheter facilitates implantation of the catheter in the urethra by enabling pull forces, push forces, and torque forces to be transmitted from the tool through the catheter to the proximal portion of the catheter without undue stress on the urethra. The element is extendible and retractable to position the catheter between stressed and relaxed states while maintaining engagement to the catheter proximal portion. The tool, element and tip member are removable from the catheter after implantation of the catheter in the urethra.
