Contraceptive transcervical fallopian tube occlusion devices and their delivery
First Claim
1. A female contraceptive method comprising:
- delivering a first expandable anchor to a first location of a female reproductive organ, the first expandable anchor being radially restrained before being delivered, the first expandable anchor being delivered through a shaft which is transcervically introduced;
delivering a second expandable anchor to a second location of a female reproductive organ, the second expandable anchor being radially restrained before being delivered, the second expandable anchor being adjacent a straight section of a contraceptive device after being delivered, wherein the straight section comprises a substantial portion of the contraceptive device; and
performing an operation with the shaft after the delivery of the first expandable anchor but before the delivery of the second expandable anchor.

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 imposing a secondary shape on a resilient structure, 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. The resilient structure is then restrained by the walls of the fallopian tube, imposing anchoring forces as it tries to resume the secondary shape.
