Abstract

Contraceptive devices that provide substantially immediate and permanent sterilization are described herein. Systems and methods for transcervically delivering the contraceptive devices are also described herein. The contraceptive device may include an expandable implant. The implant includes hydrogel to provide substantially immediate sterilization, and tissue in-growth fibers to provide permanent sterilization. As an alternative or in combination to hydrogel, the implant may include copper or cupric ions to provide substantially immediate sterilization. The implant may also include hydrogel to improve trackability of the implant through an ovarian pathway.

Description

technical field

[0001] The present invention relates to the field of contraceptive devices, and more particularly to contraceptive devices comprising hydrogels. Background technique

[0002] Female contraception and / or birth control can be achieved by objects (eg, coils) that are introduced transcervixally into the fallopian tubes to prevent pregnancy. Devices, systems and methods for such contraceptive methods have been described in various patents and patent applications assigned to the present assignee. For example, PCT Patent Application No. 99 / 15116, US Patent No. 6,526,979, and US Patent No. 6,634,361, which are hereby incorporated in their entirety, describe devices that are inserted transcervically into the ostia of the fallopian tubes and are mechanically secured within the fallopian tubes. The devices described in these patents and patent applications promote tissue ingrowth around and within inserted devices, which may be referred to as implants or inserts. One ...
