  • Publication number: 20170165103
    Abstract: A method of manufacturing an intrauterine device (IUD) for contraception that has a desired copper elution rate is described. The method may involve selecting an elongate shape memory member comprising a first metal having a first galvanic potential, selecting at least one attachment member comprising a second metal having a second galvanic potential that is different from the first galvanic potential, attaching the attachment member(s) to the shape memory member, and shaping the shape memory member to form a frame of the intrauterine contraceptive device. The first metal and the second metal are specifically selected as materials for the shape memory member and the attachment member(s), in order to achieve the desired copper elution rate.

  • Patent number: 9610191
    Abstract: An intrauterine contraceptive system may include a contraceptive intrauterine device, a retrieval thread permanently attached to the intrauterine device and an insertion device for inserting the intrauterine device into a uterus. The system may also include a release thread releasably coupled with the intrauterine device. The intrauterine device may be deployable out of a distal end of the insertion device and may be configured to change from a delivery configuration when housed in the insertion device to a deployed configuration when deployed in a uterus. The retrieval thread and the optional release thread may be at least partially housed within the insertion device during insertion of the intrauterine device into the uterus. The release thread may extend from the intrauterine device through the insertion device to an attachment point at or near a proximal end of the insertion device.

  • Publication number: 20170056237
    Abstract: A system for treating a fallopian tube to promote contraception includes a catheter device, a tissue disrupting head coupled with the catheter device, and a fluid delivery port for delivering a sclerosant to the mucosal lining of the fallopian tube before, during or after disruption of the mucosal lining by the tissue disrupting head. The catheter device may include a handle and a catheter shaft having a proximal end coupled with the handle and a distal end sized and configured to be advanced through a cervix and into the fallopian tube. The tissue disrupting head may include at least one tissue disrupting member configured to operable to mechanically disrupt a mucosal lining of the fallopian tube by contacting the tissue disrupting member with the mucosal lining and moving the tissue disrupting head. The fluid delivery port may be located in the catheter shaft or the tissue disrupting head.

  • Publication number: 20160331579
    Abstract: A method for promoting contraception by placing a contraceptive device within a uterus without blocking fallopian tubes may involve advancing a distal end of a delivery device through a cervix, advancing the contraceptive device comprising an elongate shape memory member out of the distal end of the delivery device and into the uterus, and limiting inferior migration of the contraceptive device within the uterus. Inferior migration may be limited by allowing the contraceptive device to assume a shape, when subjected to pressure that tends to cause a downward migration of the device within the uterus, in which an expandable middle portion of the device is expanded to contact the inner wall of the uterus and thus limit the downward migration of the device.

  • Publication number: 20150101613
    Abstract: An intrauterine contraceptive device may include a frame made completely or partially of a first metal having a first galvanic potential and at least one metallic member coupled with the frame that is made of a second metal having a second galvanic potential different from the first galvanic potential. In some embodiments, the first galvanic potential may be more anodic than the second galvanic potential. In alternative embodiments, the first galvanic potential may be more cathodic than the second galvanic potential. In one embodiment, the first metal is Nitinol, and the second metal is copper. In some embodiments, the first and second galvanic potentials may be configured to achieve, at least approximately, a desired copper ion elution rate for the intrauterine device.
