Publication number: 20120078230Abstract: Contraceptive methods, systems, and devices generally improve the ease, speed, and reliability with which a contraceptive device can be deployed transcervically into an ostium of a fallopian tube. The contraceptive device may remain in a small profile configuration while a sheath is withdrawn proximally, and is thereafter expanded to a large profile configuration engaging the surrounding tissues, by manipulating one or more actuators of a proximal handle with a single hand. This leaves the other hand free to manipulate a hysteroscope, minimizing the number of health care professional required to deploy the contraceptive device.Type: ApplicationFiled: November 11, 2011Publication date: March 29, 2012Applicant: CONCEPTUS, INC. A California CorporationInventors: Christian Lowe, Don Gurskis, Ashish Khera, Monica Barnhart, Steven Bacich, Betsy Swann, Roberto Silva-Torres

Publication number: 20120055492Abstract: 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 copper alloy. The device is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has 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 s effected by passing a current through there resilisent structure to the tubal walls.Type: ApplicationFiled: November 11, 2011Publication date: March 8, 2012Inventors: Julian N. NIKOLCHEV, Dai T. TON, Ashish KHERA, Donnell W. GURSKIS, Steven BACICH
