Deployment actuation system for intrafallopian contraception
First Claim
Patent Images
1. A contraceptive delivery system comprising:
- a contraceptive device insertable into a female reproductive organ, the contraceptive device having an inner portion and an outer portion surrounding the inner portion, wherein the outer portion is expandable from a small profile configuration to a large profile configuration;
a release catheter having a proximal end, a distal end and a lumen extending therethrough, wherein the distal end of the release catheter releasably engages the contraceptive device;
a core shaft extending through the lumen of the release catheter, the core shaft being releasably coupled to the contraceptive device;
a handle connected with a proximal end of the core shaft, the handle having a size and shape suitable for gripping with a hand;
a first actuator mounted on the handle, wherein movement of the first actuator by hand causes the contraceptive device to expand and affix to the female reproductive organ; and
a second actuator mounted on the handle, wherein movement of the second actuator by hand causes the contraceptive device to be decoupled from core shaft.

Abstract
Contraceptive methods, systems, and devices generally improve the ease, speed, and reliability with which a contraceptive device can be deployed transcervically into an ostium of a fallopian tube. The contraceptive device may remain in a small profile configuration while a sheath is withdrawn proximally, and is thereafter expanded to a large profile configuration engaging the surrounding tissues, by manipulating one or more actuators of a proximal handle with a single hand. This leaves the other hand free to manipulate a hysteroscope, minimizing the number of health care professional required to deploy the contraceptive device.
