Patent number: 6712810Abstract: Methods and devices for occlusion of the fallopian tubes of a woman. The method involves thermally damaging the lining of the utero-tubal junction with relatively low power, followed by placement of a reticulated foam plug. In one embodiment, vascularized tissue grows into the plug and prevents or discourages formation of scar tissue around the plug. Another embodiment with a relatively small foam pore size encourages formation of a vascularized capsule around the plug. The presence of this vascularized capsule limits the patient's foreign body response, so that the capsule does not constrict around the plug. Also presented is a catheter designed for wounding the epithelial layer of the utero-tubal junction, and a method of using the catheter to form a long yet shallow lesion in the utero-tubal junction.Type: GrantFiled: March 16, 2001Date of Patent: March 30, 2004Assignee: Adiana, Inc.Inventors: Douglas C.

Patent number: 6550480Abstract: Disclosed are occluders and methods of their use. The occluders comprise shape-memory polymeric materials which, when heated above their crystalline melting temperatures, may be deformed from a first configuration into a second configuration. The occluder is then held in the deformed shape until it cools to a temperature below its crystalline melting temperature (Tm) whereby it holds the deformed shape of the second configuration by virtue of the recrystallization of the polymeric occluder material. Upon reheating the occluder above its Tm, the occluder will resume its original shape. In this manner, an occluder which has been deformed to reduce its diameter may be inserted into and positioned within a target lumen in the body and then allowed to warm to body temperature whereby it resumes its original diameter and results in the occlusion of the lumen. The occluders, according to preferred embodiments, may be used for reversible sterilization of mammals, among other surgical and non-surgical uses.Type: GrantFiled: January 31, 2001Date of Patent: April 22, 2003Assignee: Numed/Tech LLCInventors: Tatyana Feldman, Wei Wang

Patent number: 6378524Abstract: 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 contact 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 ablation of a portion of the fallopian tube which thereby causes necrosis and ultimate fibroses of the fallopian tube.Type: GrantFiled: February 22, 2000Date of Patent: April 30, 2002Inventor: Jesse M. Jones

Patent number: 6357443Abstract: A removable fallopian tube plug includes an elongated shaft member that has a diameter dimensioned for insertion into a human fallopian tube. The shaft has an imagable portion located at each of a distal end and a proximal end. A plurality of flexible fingerlike protrusions are affixed to at least a portion of the shaft, and are movable between a first position generally adjacent the shaft and a second position extending radially outward therefrom. The protrusions are biased to the second position and are adapted for closely engaging the fallopian tube when in the second position, and they are further arrayed radially and axially so as to form a barrier sufficient to prevent a passage of an ovum or a spermatozoa in an axial direction.Type: GrantFiled: November 9, 1999Date of Patent: March 19, 2002Assignee: Synergyn Technologies, Inc.Inventor: Randall A. Loy

Publication number: 20020020417Abstract: The invention provides intrafallopian devices and non-surgical methods for their placement to prevent conception. The efficacy of the device is enhanced by forming the structure at least in part from copper or a copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has a helical outer surface, together with a portion of the resilient structure which is biased to form a bent secondary shape, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. Optionally, permanent sterilization is effected by passing a current through the resilient structure to the tubal walls.Type: ApplicationFiled: July 23, 2001Publication date: February 21, 2002Inventors: Julian N. Nikolchev, Dai T. Ton, Ashish Khera, Donnell W. Gurskis, Steven Bacich

Patent number: 6346102Abstract: A device for sterilizing females by occluding the uterotubal junction. The device includes a catheter with a releasable heat generating plug which is used to thermally damage the uterotubal junction and cause it to constrict around the plug, after which the plug is released from the catheter and left in place in the uterotubal junction.Type: GrantFiled: May 26, 2000Date of Patent: February 12, 2002Assignee: Adiana, Inc.Inventors: Douglas C. Harrington, Brett Bowman, Peter M. Breining

Patent number: 6309384Abstract: Methods and devices for occlusion of the fallopian tubes of a women. The method involves thermally damaging the lining of the utero-tubal junction with relatively low power, followed by placement of a reticulated foam plug. In one embodiment, vascularized tissue grows into the plug and prevents or discourages formation of scar tissue around the plug. Another embodiment with a relatively small foam pore size encourages formation of a vascularized capsule around the plug. The presence of this vascularized capsule limits the patient's foreign body response, so that the capsule does not constrict around the plug. Also presented is a catheter designed for wounding the epithelial layer of the utero-tubal junction, and a method of using the catheter to form a long yet shallow lesion in the utero-tubal junction.Type: GrantFiled: February 1, 1999Date of Patent: October 30, 2001Assignee: Adiana, Inc.Inventors: Douglas C. Harrington, Victoria E. Carr-Brendel, Brett S. Bowman

The efficacy of the device is enhanced by forming the structure at least in part from copper or a copper alloy. The device is anchored within the fallopian tube by imposing a secondary shape on a resilient structure, the secondary shape having a larger cross-section than the fallopian tube. The resilient structure is restrained in a straight configuration and transcervically inserted within the fallopian tube, where it is released. The resilient structure is then restrained by the walls of the fallopian tube, imposing anchoring forces as it tries to resume the secondary shape.Type: GrantFiled: June 7, 1995Date of Patent: January 23, 2001Assignee: Conceptus, Inc.Inventors: Julian Nikolchev, Dai Ton, Amy Thurmond

Patent number: 6165492Abstract: A method and composition for effecting chemical necrosis of a tissue lining of a mammalian body cavity, particularly a uterine endometrium, by delivering a caustic tissue necrosing composition, e.g., a silver nitrate and dextran paste, to the tissue to be necrosed and allowing the paste to remain in contact with the target tissue for a period of time sufficient to chemically necrose substantially the entirety of the tissue lining, and then contacting the caustic composition with a deactivating agent, e.g., an aqueous sodium chloride solution, thereby rendering the caustic composition non-caustic, and then rinsing the cavity. Compositions and methods for delivering medicaments are also disclosed.Type: GrantFiled: February 18, 1999Date of Patent: December 26, 2000Inventor: Robert S. Neuwirth
