摘要:
A system for ligating a uterine artery in a patient generally includes a suture transfer tool, suture transfer darts, and one or more sutures. The suture transfer tool includes an upper jaw that is pivotally joined to a lower jaw. The lower jaw of the tool includes a number of suture capturing pins. The suture transfer darts are configured to be tissue piercing and are positionable within the suture capturing pins. Each end of the suture is connected to a suture transfer dart. When operating the tool, the suture transfer darts pierce through the tissue to either side of a patient's cardinal ligament, which contains the uterine artery, and simultaneously present an end of the suture to either side of the cardinal ligament. As such, the suture is in an open loop configuration about the cardinal ligament and can be tied tight to the ligament to occlude the uterine artery.

A delivery system for delivering an occluding device to a body lumen comprises an elongated shaft having a proximal end and a distal end, a delivery means for delivering the occluding device to a desired location within the body lumen, and a flexible atraumatic tip on the distal end of the elongated shaft. The distal end of the elongated shaft is insertable into the body lumen. The atraumatic tip is configured to guide the elongated shaft through the body lumen while avoiding perforation of the body lumen.

Surgical procedures, tools, and kits particularly suited to effect uterine artery ligation in a minimally invasive manner to treat uterine fibroids or other conditions of the uterus are disclosed. An incision through the fornix is made to access the uterine arteries supported by the cardinal and uterosacral ligaments. A distal end of one or more sutures is passed around each uterine artery and a portion of the ligament supporting and enclosing the uterine artery, wherein the portion may include a uterine vein. The passage is effected by directing a suture distal end along a first side of the portion of the ligament beyond to the fornix incision, then through the ligament, and then back proximally along the second ligament side toward the fornix incision.

A delivery system for deploying an occlusion device comprises a piston having a threaded proximal end, an elongated delivery catheter having a proximal end, a distal end, and an inner lumen extending between the proximal and distal ends of the delivery catheter, and a drive mechanism comprising an internally threaded nut member and a spring member. The piston, which is coupled at a distal end to the proximal end of the delivery catheter, is moveable between a first axial position and a second axial position. The internally threaded nut member is configured to receive the threaded proximal end of the piston. The spring member, which is coupled to the internally threaded nut member, is configured to rotate the nut member to drive the piston from the first axial position toward the nut member to the second axial position. Driving the piston toward the nut member retracts the attached delivery catheter and deploys an occlusion device from within the inner lumen and through the distal end of the delivery catheter.

A scope seal and method for sealing a working channel of a hysterscope is disclosed. The scope seal includes a proximal end through which a catheter can be received, a distal end that communicates with a fitting on the hysteroscope, and a substantially hollow body longitudinally extending between the proximal end and the distal end. The scope seal also includes a catheter sealing mechanism positionable within the body, a shaft seal, a chamber configured to receive the fitting of the hysteroscope and a pressure relief chamber. The catheter sealing mechanism can be any one of a duckbill valve, a conic valve, and/or a membrane. The chamber for receiving the fitting on the hysteroscope communicates with the fitting positioned on a proximal end of the hysteroscope, where the working channel of the hysteroscope accommodates a catheter therethrough in order to perform in vivo procedures.

The present invention provides a urethral prosthesis including a first and a second arm that join to form a junction, and a stem that is also joined to the junction. The junction is adapted to exert sufficient pressure on a portion of a patient's urethra to prevent unintentional voiding of the patient's bladder. However, upon exerting a tension force on the stem, the pressure exerted by the junction is reduced such that the patient's bladder may be intentionally voided.

The invention provides a medical screwdriver having a sleeve that can be coupled to the medical screwdriver without the need to align the sleeve to the medical screwdriver. The medical screwdriver includes a body portion having a receiver, a drive shaft, a sleeve, and a coupling connecting the sleeve to the receiver. The sleeve surrounds at least a portion of the drive shaft when coupled to the receiver. The coupling comprises an end of the sleeve and the receiver of the body portion. The end of the sleeve and the receiver are designed so that the end of the sleeve can be coupled with the receiver of the body portion without rotationally aligning the end of the sleeve to the receiver of the body portion and so that the sleeve is prevented from rotating in a direction of rotation during use.

A media magazine container utilizes a recirculating latch mechanism that makes minimal use of a solenoid and includes a safety door. The latch mechanism includes a contoured latch arm with a configured opening and a shoulder, a slider moving in a slider track and coupled to the latch arm, and a restoring device, such as a spring, for providing a counteractive force. The mechanism latches a magazine into the container by capturing magazine pins in the shoulder of the latch arm. The magazine can be easily unlatched by forcing the latch arm downward with an actuating device, causing the slider and configured opening to interact. As the magazine is extracted from the container, the slider and configured opening interact in such a manner that when the magazine is fully extracted the latch arm is back to the original position where it first received the magazine, and is ready to receive another. A safety door blocks passage to any objects entering the container other than a media magazine. The latch mechanism can further actuate an external access door.

A medical illumination device including a base, a light housing and a flexible body. The base includes a power source and an attachment component. The attachment component further includes a first portion and a second portion, the first portion attachable to an attachment point and the second portion repositionable relative to the first portion without detaching the first portion from the attachment point. The flexible body has a self-sustaining shape with at least one bendable shaft positioned inside the flexible body. The base provides stability for repositioning of the flexible body. The base has sufficient surface area contacting the attachment point, sufficient base weight, and sufficient holding strength to effectively provide stability for repositioning of the flexible body. The base comprises at least 50% of the weight of the device and has a surface area of at least 1.0 square inch.
