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. Tal, Patrick N. Gutelius, Mark J. DeBisschop, Oleg Shikhman, Pasquale Patrizio, Bob H. Katz

Patent number: 9016280Abstract: An intrauterine device for occluding orifices of fallopian tubes includes a resilient body having an elongated member with a first end and a second end. The elongated member further includes a first leg ending with the first end of the elongated member, a second leg ending with the second end of the elongated member and a connection member positioned therebetween. A first orifice plug is secured at the first end of the elongated member and a second orifice plug is secured at the second end of the elongated member. The first and second orifice plugs are shaped and dimensioned to seat at the orifices of the fallopian tubes or within the fallopian tubes as the elongated member spreads outwardly with the first end and second end moving apart.Type: GrantFiled: April 18, 2012Date of Patent: April 28, 2015Assignees: Yale University, Contramed LLCInventors: Michael G.

Publication number: 20150107598Abstract: 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.Type: ApplicationFiled: October 18, 2013Publication date: April 23, 2015Applicant: Contramed, LLCInventors: Michael TAL, Bob H.

Patent number: 8662081Abstract: 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: August 16, 2010Date of Patent: March 4, 2014Assignees: Yale University, Contramed LLCInventors: Michael G. Tal, Patrick N. Gutelius, Mark J. DeBisschop, Oleg Shikhman, Pasquale Patrizio
