    摘要: A stent delivery system is comprised of an elongated flexible advancement member which terminates in a tubular tracking member slidable over a guidewire. An inflatable balloon has proximal and distal ends, the proximal end communicating with an inflation channel, and the distal end attaching to the tracking member. The balloon portion is coextensive with but not attached to the advancement member, which is external to the balloon. A stent is positioned around the inflatable balloon, and when the balloon is inflated, the stent expands radially. The outer surface of the expanded stent has one or more projections that enhance retention of the stent.

    摘要: A torque-transmitting structure such as a guidewire or catheter is formed of a generally flat band or wire twisted so that its longitudinal edge generally forms a helix. This twisted helical portion may be attached to a proximal shaft, and a tip member may be attached to the distal end of the helical portion. In some embodiments, the device is made of a single piece of wire, and in some embodiments, a spring coil may cover the helical portion. Where the device is a fixed wire balloon catheter, the helical portion may be attached to a proximal shaft, and the balloon mounted on the helical twisted wire, a plastic sheath encasing the main shaft and wire up to the balloon for inflation of the balloon. The helical guidewire may also be used in an over-the-wire balloon catheter.

    摘要: A system and method for localized delivery of a therapeutic or diagnostic agent within a vessel is provided. The system and method provide for adjustability of the length of the treatment area and for reducing of pressure within the treatment area. A catheter system includes an inner elongated element, an outer elongated element positioned coaxially with respect to the inner elongated element, and a blood-release element at a distal end of the inner elongated element. A proximal occlusion element is positioned at the distal end of the outer elongated element, proximal to an outlet port. A distal occlusion element is positioned at a distal end of the inner elongated element. The distal end of the inner elongated element is distal to and movable with respect to the outer elongated element distal end.

    摘要: An apparatus for mounting a radially expandable intraluminal stent or stented graft onto a delivery catheter. The apparatus comprises a hollow housing defining an interior chamber and a fluid port which communicates with the interior chamber. Disposed within the interior chamber of the housing is a collapsible, resilient tubular sleeve which is sized to receive a portion of the delivery catheter having the stent or stented graft positioned thereupon. The sleeve includes an open end which communicates with the exterior of the housing. The pressurization of the interior chamber of the housing via the fluid port facilitates the uniform radial compression of the sleeve, with the depressurization of the housing via the fluid port causing the sleeve to resiliently return to an uncompressed state.
