Contraceptive transcervical fallopian tube occlusion devices and methods
First Claim
1. A sterilizing device for a patient'"'"'s reproductive lumen, comprising an expandable occluding component configured for deployment within the patient'"'"'s reproductive lumen which has at least one impermeable barrier component which is substantially impermeable to the passage of reproductive cells, and at least one permeable component which facilitates tissue growth into or onto the occluding component;
- wherein the outer diameter of the device is configured to be large enough, in an expanded state, to engage the lumen wall;
wherein the device comprises an outer and inner coil and fibrous element radially disposed between the coils.

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.
