Publication number: 20170165103Abstract: 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.Type: ApplicationFiled: February 24, 2017Publication date: June 15, 2017Applicant: CONTRAMED, LLCInventors: Michael TAL, Bob H.

Patent number: 9510088Abstract: An intrauterine device for applying pressure to the walls of the uterine cavity includes a resilient body having an elongated member which includes a first end and a second end which are resiliently biased away from each other. The first end of the elongated member includes a first leg having a first end and a second end. The second end of the elongated member includes a second leg having a first end and a second end. A connection member is positioned between the first end of the first leg and the first end of the second leg. A first plug member is secured at the second end of the first leg and a second plug member is secured at the first end of the second leg. The first and second plug members are shaped and dimensioned for bearing against the walls of the uterine cavity as the elongated member spreads outwardly with the first end and the second end moving apart. A method for preventing conception within the uterine cavity is also disclosed.Type: GrantFiled: July 24, 2013Date of Patent: November 29, 2016Assignees: YALE UNIVERSITY, CONTRAMED LLCInventors: Michael G.

Patent number: 9492311Abstract: An intrauterine device for applying force to a wall of a uterus to promote contraception without blocking the fallopian tubes may include an elongate member formed of a resilient material and having a default expanded configuration and a spring portion disposed approximately at a midpoint between two ends of the elongate member. The IUD may also include two tissue contact members, one tissue contact member disposed at one of the two ends of the elongate member and the other tissue contact member disposed at the other end. The tissue contact members may generate a laterally directed force against the wall of the uterus when the intrauterine device assumes its default expanded configuration.Type: GrantFiled: August 13, 2014Date of Patent: November 15, 2016Assignees: Yale University, ContraMed, LLCInventors: Michael G.

Patent number: 9265652Abstract: 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.Type: GrantFiled: August 14, 2012Date of Patent: February 23, 2016Assignee: CONTRAMED, LLCInventors: Michael Tal, Bob H.
