摘要:
In a preferred application, e.g., the repair of vaginal prolapse after relocation of the vagina and any organs displaced by the prolapse, corrective surgery is initiated by applying a hollow tubular element, formed to forcibly insert a barbed anchor attached to a distal end of a first length of suture, without any incision, from the inside of the vagina through the vaginal wall (the supported tissue) into selected support tissue within a patient's pelvis. This involves puncturing and thus locally severe physical distressing of both the supported tissue and the support tissue. The barbed anchor is left in the support tissue as the tubular element is then withdrawn from the support tissue and out of the vagina, leaving the proximate end portion of the suture extending through the vaginal wall into the vagina. A second such anchor, with a second length of suture attached thereto, is similarly inserted adjacent to the first anchor. The proximate end portions of the sutures are tied to each other inside the vagina, to thereby secure the vaginal wall to the support tissue with corresponding punctures formed in each by the insertions of the two anchors being thereby held in respective, precisely aligned, intimate contact during healing. This results in a pair of fused scars that cooperate to permanently bond the vaginal wall locally to the support tissue. If the sutures and/or the anchors are made of absorbable material they will all eventually disappear and the fused scars will provide the permanent bonding. If the anchors are made of non-absorbable material they may remain where located. A plurality of such paired fused-scar bonds may be generated, at the surgeon's discretion, to ensure adequate support for the repaired vagina. The apparatusand method can be readily adapted to similarly effect deliberate, local, beneficial bonding between other adjacent living tissues in a patient.

An implantable device for treating a patient suffering from female urinary stress incontinence includes an elongate sling for supporting the urethra, the sling having first and second ends. First and second tabs extend from the first and second ends of the sling, respectively for engaging supportive tissue superior to the portion of the urethra being supported. Each tab has a ratcheted section of alternating relatively projecting and relatively recessed portions for engaging the supportive tissue.

A surgeon-implantable, fluid-filled, flexible device for automatically controlling stress incontinence in female patients employs a flexible diaphragm element positioned in the patient's abdominal space to compress in response to increases in intraabdominal pressure. Upon such compression of the diaphragm, pressurized fluid flows therefrom via a flexible tubing, optionally via a flow control element, to an inflatable urethra-constricting element in fluid communication therewith and positioned over the patient's urethra close to her bladder neck. Thus, when the patient experiences an increase in intraabdominal pressure, e.g., when she coughs, fluid from the diaphragm flows rapidly to the urethra-constricting element which presses against and forcibly constricts the urethra adjacent thereto. Upon abatement of the intraabdominal pressure, the flow control element releases fluid from the urethra-constricting element which then ceases to press on the urethra.

A compact, self-contained lighting system is attachable to a surgical tool to enable a user to selectively direct light at a site where the tool is to be applied. The system has a power unit that may contain rechargeable power cells, a malleable electrical connection element, and a light-emitting element powered thereby to emit high intensity white light, preferably from an LED. The system ensures against tissue damage due to inadvertent overheating by continuously removing byproduct heat from the light-emitting element, via the connection element, to the power unit with portions of each of these components serving as respective heat sinks and/or as thermal conduits to facilitate this process. The removed heat is dissipated to the ambient atmosphere, the surgical tool and even the user, and permits safe prolonged operations in confined regions of a patient's body.

A guidewire or other guide element has an elastically deformable distal end portion that is formed to have an unstrained shape or other features selected to allow the guide element to be safely retained inside a female's urinary bladder after placement therein via a tubular catheter by a doctor. The proximal end of the guide element extends out of her urethra to be easily accessible to her. When she needs to urinate, she passes the proximal end of the guide element into the distal end of another tubular catheter by herself and guides the catheter along the guide element into her bladder to pass out urine through the catheter. When her condition has improved, she or her doctor can withdraw the guide element via a similar catheter.

A cautery tool is provided with a compact, lightweight, user-directable lighting facility that can be powered by either a shared external power source from which a power flow is shared continuously with the cautery function, by a supplemental self-contained power cell that may be recharged by a portion of the external power for use independently of the cautery function, or by sharing of a self-contained power cell by the cautery and the lighting functions. Waste heat generated during exercise of the lighting function is continuously removed from a light-emitting element by electrical conductors also serving as heat transfer conduits.
摘要:
A compact, self-powered, selectively-mountable lighting unit provides light directable by a user to an operation site in a confined space to enable the user to operate a tool therein. The lighting unit is detachably mountable in a variety of ways either to a user-selected location on any suitable surgical instrument,or at the user's option to an adjacent location within the confined space, to facilitate well-lit and accurate viewing thereat. The lighting unit may be adapted to provide lighting of selected frequency, in an adjustable focus ranging from substantially diffuse light to a tightly focused beam. A known dead-soft element may be included to enable the user to adjust orientation of the delivered light.
