摘要： A device for delivering an expandable member to a luminal structure in a patient is described. In some embodiments, the device has a carrier member, with a carrier lumen extending at least partially therethrough. The device can have an elongate member that extends through the carrier lumen across a first notch in the carrier member. The device can have an expandable member that expands within and engages the luminal structure, can be carried by the carrier member, and has a first portion that fits within the first notch. When the elongate member extends through the carrier lumen and across the first notch, the elongate member secures the first portion to the carrier member. The elongate member is configured to move axially through the carrier lumen such that the elongate member permits release of the first portion from the carrier member and expansion of at least part of the expandable member.

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.

摘要： A method of forming an annularly expanding and retracting gripping and releasing mechanism providing a series of flexible tubes, comprising providing (1) a series of flexible tubes, (2) a corresponding series of wires, each of which includes a movable wire section and relatively short fixed wire section integrally connected with one end of the movable wire section by a kink configured so that the wire sections extend in longitudinally coextensive relation therefrom; (3) a series of tubular elements of thermoplastic material; and (4) a series of heat shrinkable sleeves assembling a distal end portion of each flexible tube with a fixed wire section, a tubular element and a heat shrinkable sleeve so that the fixed wire section extends along the exterior periphery of the flexible tube with the kink disposed outwardly of the distal end thereof. The tubular element is disposed in surrounding relation to the fixed wire section and the flexible tube and the heat shrinkable sleeve is disposed in surrounding relation to the tubular element. The method further comprises applying heat to the exterior of each heat shrinkable sleeve at a temperature sufficient to contract the sleeve and soften the thermoplastic material of the tubular element surrounded thereby so that the contraction of the sleeve molds the softened thermoplastic material into adhered contact with the exterior surfaces of the surrounded fixed wire section and flexible tube.
