1. A contraceptive delivery system comprising:
- a contraceptive device insertable into a female reproductive organ, wherein the contraceptive device includes an outer portion which is expandable from a small profile configuration to a large profile configuration;
a core shaft 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; and
an actuator system on the handle which causes the contraceptive device to expand and engage with the female reproductive lumen while connected to the core shaft, and to be decoupled from the core shaft after the contraceptive device has been expanded and engaged with the female reproductive lumen, wherein the actuator system comprises a trigger actuator which causes the contraceptive device to expand and a rotatable knob to decouple the contraceptive device from the 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 The contraceptive device may remain in a small profile configuration while a sheath is withdrawn proximally, and is thereafter expanded to a large profile configuration engaging the surrounding tissues, by manipulating one or more actuators of a proximal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.
