摘要： A rapid exchange catheter extends from a proximal portion which remains outside of a patient's body during use to a distal portion which, during use, is located within a body lumen adjacent to a target area to be treated, wherein the proximal and distal portions are coupled by a medial portion. The catheter comprises a guide wire lumen extending longitudinally through the distal portion and a guide wire receiving channel formed by an outer surface of the medial portion, wherein the guide wire lumen is open to a distal end of the channel.

摘要： A steerable imaging catheter is provided, including an elongated catheter tube, at least one steering cable extending along the catheter tube to control the movement of the distal end thereof, and a fiber optic cable extending along the catheter tube. The fiber optic cable transmits illumination light from its proximal end to its distal end and transmits an image from its distal end to its proximal end. In one embodiment, two or more steering cables are used, and the catheter tube is configured to have greater flexibility near its distal end than its proximal end so as to concentrate the movement (flexing) of the catheter tube at its distal end. The use of two or more steering cables, together with the catheter tube having varying flexibility, permit better control of the distal end of the catheter tube while reducing undue twisting of the remainder of the catheter tube.

摘要： A medical retrieval device is used to retrieve and/or fragment stones (and/or other objects) from the body of a patient. The device has a retrieval basket with a releasable tip. The tip release is designed to release in a controlled pre-determined manner and under a predetermined force before any other component of the device fails due to a force exerted on the basket.

摘要： A guidewire exit tool includes a pin that is insertable into a guidewire channel of a rapid exchange-type catheter. The pin has at least one tapered end that urges a guidewire out of a slit in guidewire channel. In one embodiment the exit tool has an oval handle that is angled with respect to the longitudinal axis of the pin such that the tool can be easily grasped and moved along the guidewire channel.

摘要： A catheter system for use during biliary procedures, including a first elongate member carrying a guidewire lumen, and a channel extending longitudinally along the member which provides access to the guidewire lumen and defines two edge surfaces. A second elongate member is also included which is disposed within the guidewire lumen and mates with the cross-sectional profile of the guidewire lumen of the first elongate member, thereby converting a guidewire lumen having a C-shaped design into one having an O-shaped design. The catheter may be used in rapid exchange catheter procedures requiring the use of small diameter guidewires which would otherwise slip out of the channel during use.

摘要： Method for draining pseudocysts and stent delivery system for use therein. In one embodiment, the system comprises an inner catheter provided with a pair of longitudinal lumens. A guide wire is slidably disposed in one lumen, and a retractable needle is slidably disposed in the other lumen. A self-expandable stent is coaxially mounted around the inner catheter near its distal end, and an outer catheter is coaxially mounted around the inner catheter and the stent, the outer catheter being adapted for axial movement relative to the inner catheter and being dimensioned to maintain the stent in a compressed state. In use, an endoscope is intraorally introduced into a patient's stomach, and the distal end of the system is inserted therethrough. The needle is advanced to form perforations in the stomach and pseudocyst. The inner catheter is then inserted through the perforations, and the outer catheter is retracted, allowing the stent to expand and interconnect the stomach and pseudocyst. The endoscope and the rest of the delivery system are then withdrawn from the patient.

摘要： A ligating instrument is provided, including an elongate member, such as a tube, having a lumen, the elongate member extending from a proximal actuator member to a distal ligating band dispenser. A pull line may extend through the lumen of the elongate member, with a proximal end of the pull line connected to the actuator member and a distal end of the pull line connected to the ligating band dispenser, wherein actuation of the actuator member draws the pull line in a proximal direction through the elongate member to deploy the ligating bands. The ligating band dispenser may be adapted to be mounted on the distal tip of an endoscope, and the elongate member may be adapted to be positioned outside of the endoscope from the ligating band dispenser to the actuator member. Alternatively, a ligating instrument may be provided for use with an endoscope, wherein a pull line of the ligating instrument is adapted to be positioned outside of the endoscope, wherein the pull line may be secured to the endoscope by clips or some other means. In a method of using a ligating instrument with an endoscope, a distal ligating band dispenser is attached to a distal tip of an endoscope, and a pull line of the ligating instrument is extended on the outside of the endoscope, such that the pull line extends, on the outside of the endoscope, from the distal ligating band dispenser to a proximal actuator member.
