TRANSCERVIKAL EINSETZBARE EMPFÄNGNISVERHÜTUNGSVORRICHTUNG ZUM VERSCHLUSS DER EILEITER |
摘要 |
The invention provides an intrafallopian device to prevent conception. The efficacy of the device (10) is enhanced by forming the structure at least in part from copper or a copper alloy. The device (10) is anchored within the fallopian tube by a lumen-traversing region of the resilient structure which has a 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 sterilisation is effected by passing a current through the resilient structure to the tubal walls. A device further includes openings between an inner and outer surface to allow for in-growth of tissue. |
