Embodiment Construction

[0025] Contraceptive devices that provide substantially immediate and permanent birth control are described herein. Also described herein are systems and methods for transcervical delivery of contraceptive devices. Contraceptive devices may include expandable implants. The implant includes a hydrogel to provide substantially immediate birth control and a tissue ingrowth promoter or fibers to provide permanent birth control. Once the device with the hydrogel is deployed, the hydrogel provides immediate birth control by swelling in the physiological environment and tissue ingrowth promoters such as polyester fibers promote tissue ingrowth to permanently occlude The fallopian tube in which the device is implanted. As an alternative to or in combination with a hydrogel, the implant may contain copper or copper ions to provide substantially immediate birth control. The implant may also include a hydrogel to improve the trailing of the implant through the ovarian passage (to prov...

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 ...
