1. An occlusion system comprising:
- a sheath having a lumen; and
an occluding device disposed within the lumen and being releasable from the lumen, the occluding device comprising an expandable outer coil and an inner coil coaxially disposed within the outer coil, the inner coil including a distal end distal to a distal end of the outer coil and a proximal end within the outer coil such that a proximal end of the outer coil trails proximally the proximal end of the inner coil.

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 The contraceptive device may remain in a small profile configuration while a sheath is withdrawn proximally, and is thereafter expanded to a large profile configuration engaging the surrounding tissues, by manipulating one or more actuators of a proximal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.
