    摘要: Catheters for intrafallopian contraceptive delivery generally improve the ease, speed, and reliability with which a contraceptive device can be deployed transcervically into an ostium of a fallopian tube. One or more coils disposed along the catheter near its distal end enhance the ability of the catheter through a tortuous lumen, such as a fallopian tube, without significant kinking or narrowing of the inner diameter of the catheter. A coil also helps maintain the inner diameter of the catheter when it elongates during removal, thus facilitating delivery of a contraceptive device from the catheter. A variable-flexibility distal portion in some embodiments further enhances maneuverability and pushability.
