Estimating the term…
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 a copper alloy. The device 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 sterilization is effected by passing a current through the resilient structure to the tubal walls.
A method comprising:
A device for inhibiting conception in a patient having a fallopian tube with an ostium and an adjacent tissue, the device comprising a body having a lumen with a fiberous polyester material permanently affixed at least in part therein to facilitate tissue ingrowth into the body in a manner which provides permanent sterilization, the body insertable transcervically into tho ostium of the fallopian tube and adapted to expand from a first configuration to a second configuration so as to be retained therein during tissue ingrowth into the polyester material, the body comprising a primary coil and a secondary coil, the secondary coil disposed around a portion of the primary coil.
