INSERTION/DEPLOYMENT CATHETER SYSTEM FOR INTRAFALLOPIAN CONTRACEPTION

摘要

Contraceptive methods, systems, and devices generally improve the ease, speed, and reliability with which a contraceptive device (12) can be deployed transcervically into an ostium of a fallopian tube. A distal portion (24) of the contraceptive device (12) can function as a guidewire (10). The proximal portion (20) may remain in a small profile configuration while a sheath (14) is withdrawn proximally, and is thereafter expanded to a large profile configuration engaging the surrounding tissues.
