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.

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： Delivery catheters and systems are adapted for delivering multiple discreet prostheses in body lumens. An exemplary delivery catheter comprises a sheath, a pusher for moving the prostheses relative to the sheath, and a valve member for selectively retaining the prostheses in the sheath. For balloon expandable stents, an elongated shaft and an expandable member are slidably disposed in the sheath, and the prostheses are positionable on the expandable member for deployment in the body lumen. The valve member allows a selected number of prostheses to be deployed from the sheath while retaining other prostheses within the sheath.

摘要： Apparatus and methods for delivering stents or stent segments to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Mechanisms are described for measuring the distance that the sheath is moved relative to the catheter shaft and/or the guidewire tube, or for counting the number of stents exposed and/or deployed by operation of the device. These mechanisms include optical counting mechanisms, inductive, resistive, and/or magnetic resonating counters, electrical contact counters, and mechanical counters.
