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.

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.

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.

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 and/or device embedment within the uterus.

Abstract

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 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.

Abstract

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.
