The present invention is a device for delivering a self-expanding stent. The device has an inner shaft and an outer shaft moveable with respect to the inner shaft. The self expanding stent is received on the inner shaft adjacent its distal end. A tapered tip is located on the inner shaft distal end and it forms a smooth transition from the delivery device to the guide wire extending therethrough. A handle allows the practitioner to deploy the stent single handedly. The stent may have its segments in a first radial configuration for deliver of the stent or the stent may have a plurality of segments in a first radial configuration and a plurality of second segments in a second radial position.

Stent delivery system

An apparatus for emitting x-rays comprises a housing which contains an anode having an electron receiving surface and a cathode having an electron emitting surface. A cable couples the anode to a source of high voltage. An optical fiber secured to the cable has a proximal end coupled to a source of optical energy and a distal end configured to direct the optical energy onto the cathode's electron emitting surface. The cathode emits electrons which strike the anode to create x-ray radiation.

Miniature x-ray emitter having independent current and voltage control

The present invention relates to a device for simultaneously treating a tumor or cancerous growth with both hyperthermia and X-ray radiation using brachytherapy. The device includes a needle-like introducer serving as a microwave antenna. Microwaves are emitted from the introducer to increase the temperature of cancerous body tissue. The introducer is an inner conductor of a coaxial cable. The introducer contains a hollow core which houses an X-ray emitter. The X-ray emitter is connected to a high voltage miniature cable which extends from the X-ray emitter to a high voltage power source. The X-ray emitter emits ionizing radiation to irradiate cancerous tissue. A cooling system is included to control the temperature of the introducer. Temperature sensors placed around the periphery of the tumor monitor the temperature of the treated tissue.

Apparatus and method for treatment of malignant tumors

The present invention is a device for delivering a self-expanding stent. The device has an inner and an outer shaft moveable with respect to the inner shaft. The self expanding stent is received on the inner shaft adjacent its distal end. A tapered tip is located on the inner shaft distal end and it forms a smooth transition from the deliver y device to the guide wire extending therethrough. A handle allows the practitioner to deploy the stent single handedly. The stent may have its segments in a first radial configuration for deliver of the stent or the stent may have a plurality of segments in a first radial configuration and a plurality of second segments in a second radial position.

An endolumenal prosthesis delivery assembly includes an endolumenal prosthesis which is delivered to a desired location within a body lumen by used of first and second delivery members. The first delivery member has a prosthesis coupler that is adapted to removeably engage the prosthesis during delivery to the desired location and to release the prosthesis and implant it at the desired location. The second delivery member has an anchor on its distal end portion which is adapted to secure the second delivery member within the body lumen distally of the desired location for stenting. Once the second delivery member is anchored, the first delivery member is slideably advanced over the second delivery member until the prosthesis is positioned at the desired location. The anchor along the second delivery member according to this assembly is either an expandable member, such as a balloon, or is otherwise adapted to engage the body lumen wall, such as by use of suction or other mechanical means. An expansion member on the first delivery member, such as provided at the prosthesis coupler, expands the prosthesis to engage the body lumen wall.
