Abstract
Abstract 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.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
80 words
A method comprising: introducing a contraceptive device transcervically into an ostium of a fallopian tube, the device comprising a body expandable from a first configuration to a second configuration, the body having a lumen with polyester fibers permanently affixed at least in part therein to facilitate tissue ingrowth into the body in a manner which provides permanent sterilization; and retaining the device while the polyester fibers induce tissue ingrowth into the device so that the ingrown device provides permanent sterilization.
Claim 2
Independent Claim
80 words
A method comprising: introducing a contraceptive device transcervically into an ostium of a fallopian tube, the device comprising a body expandable from a first configuration to a second configuration, the body having a lumen with polyester fibers permanently affixed at least in part therein to facilitate tissue ingrowth into the body in a manner which provides permanent sterilization; and retaining the device while the polyester fibers induce tissue ingrowth into the device so that the ingrown device provides permanent sterilization.
Claim 3
Dependent Claim
35 words
The method of claim 1 , wherein the body is elongate and the lumen is axial, and wherein the polyester fibers are disposed at least in part within the axial lumen of the elongate body.
Claim 4
Dependent Claim
17 words
The method of claim 1 , wherein the polyester fibers are laterally exposed about the elongate body.
