Methods, systems and devices for performing gynecological procedures. According to one embodiment, there is provided a device for occluding a fallopian tube, the device including an outer member and an inner member. The outer member may be a hollow, frusto-conical structure shaped to include an open proximal end, an open distal end, and a side wall. The outer member may be self-expandable such that the distal end is biased radially outwardly. In addition, the side wall may have a porous structure to permit the ingrowth of tissue therethrough. Tines may be provided on the outer surface of the side wall to promote the anchoring of the outer member in a fallopian tube. The inner member, which may be structured to induce scarring, may comprise an elongated fibrous body fixed at its proximal end to the proximal end of the outer member. A bore may extend distally from the proximal end of the inner member to receive a delivery rod. The inner member, which may have pores or interstices to permit the ingrowth of tissue thereinto, is coated or impregnated with a sclerosing agent.

Systems, methods, apparatus and devices for performing improved gynecologic and urologic procedures using a flowable distension media are disclosed. The system and devices provide simplified use and reduced risk of adverse events. Patient benefit is achieved through improved outcomes, reduced pain, especially peri-procedural pain, and reduced recovery times. The various embodiments enable procedures to be performed outside the hospital setting, such as in a doctor's office or clinic.

A method of sterilizing women is provided wherein a flexible hysteroscope (10), having an operating channel (11), a fluid channel (12), and an optical channel terminating at a lens (13), is passed through the cervix C and uterus to a position adjacent the utero-tubal ostium. An elongated laser catheter (15) having a radially diffusing tip (16) and coupled to a laser generator is extended from the operating channel and through the utero-tubal ostium to a position within the fallopian tube. The laser generator is then energized so as to generate energy sufficient to cause the production of oxygen free radicals which cause necrosis and ultimate fibroses of the fallopian tube.

The tubal ligation instrument of the present invention includes a structure for ligating anatomical tubes within the human or another animal body, structure for anesthetizing the anatomical tubes being ligated and structure for internally viewing the ligation procedure. An example of an anatomical tube is a Fallopian tube. The instrument further includes a structure for grasping the anatomical element. Usually the grasping structure is a rod having forceps at one end. This rod may be hollow with a valve attached in fluid communication with the rod's rearward end so that anesthesia may be caused to flow through the hollow channel in the rod. The application of anesthesia to an anatomical element is accomplished by introducing the anesthesia through the valve and into the hollow channel of the rod. Thus, a surgeon directing the forward end of the instrument to an anatomical element can apply an anesthetic agent to the anatomical element intraabdominally. In another embodiment of the present invention the hollow rod may contain lenses in its forward end and an eyepiece at its rearward end with light-carrying optical fibers running through the hollow portion of the rod to illuminate the anatomical element being ligated. Thus, a surgeon directing the forward end of the instrument to an anatomical element can view the anatomical element intraabdominally.

A ring applicator with an endoscope comprises an operation unit, an outer tube connected to the operation unit, an inner tube reciprocably inserted into the outer tube, an endoscope reciprocably inserted into the inner tube, a normally opening forceps consisting of a pair of hook-like strips secured to the distal end of the endoscope, a rubber ring mounted on the distal end portion of the inner tube, and an operation device provided at the operation unit for drawing back the endoscope only at first and then both the endoscope and the inner tube. Only by operating the operation device the rubber ring can be fed into a body cavity to clamp tissues in the body cavity, while the interior of the body cavity is being observed through the endoscope which is provided in the applicator.

摘要:
A surgical device for performing internal ligation of a fallopian tube or other tubular anatomical structure, by application of one or more ligating bands to a folded portion of the wall of the tubular structure. A method of using the device is also disclosed. The inventive method and device may be used for sterilization to prevent undesired pregnancies, or for other medical applications. One embodiment of the device includes an elongated tubular element that is inserted into the fallopian tube, a grasper that extends out of the tubular element, grasps the interior of the fallopian tube and retracts into the tubular element in a folded bundle of the fallopian tube tissue; and a pusher balloon for pushing a ligating band from the tip of the tubular element onto the tissue bundle. A fold assist mechanism may be included to help evert a section of a fallopian, or other, tube.

A ligature tool, of the type having a handle carrying an elongate body defining a fastening clip chamber in its forward part with ligature tubing holding and tensioning means carried on the body, provides improved crimping and tubing holding means. The crimping element provides a single pivotally mounted crimping dog that contacts a slit portion of an annular ligation tube clip carried in the fastening clip chamber and is movable into that chamber to crimp the sides defining the slit toward the adjacent inner surfaces of the annular clip body to fasten ligation material therebetween. The tubing holding means provide a body supporting similar laterally opposed tubing holders each having a headed vertical post about which the end portion of tubing is wound under tension before placement in an adjacent wedge-shaped slot for releasable fastening. The tubing holding body also provides tubing cutting structure.

A laparoscopic fixation, repair and ligation suture; and device has a central passageway with first and second parallel channels on opposite sides thereof. A suture extends through the central channel passageway and has a loop with a slip knot on the distal end and a pull on the proximal end. By pulling on the pull the loop can be drawn tightly about a tissue to be ligated. A nesting tube is provided in one channel to receive a suture needle attached to a loopless suture to easily suture to a body cavity wall. In another form, a tapered handle frictionally receives a suture needle attached to a looped and slip knotted suture to repair a tear or rupture in a body part by suturing through one or more laparoscopies without tying ligature knots inside the body cavity. In a third form, a curved carrying device in one channel and a ligation assist device in the other channel permits ligation of large vessels attached to a body part by fibrous tissue.
