Self-expanding devices and methods therefor
Described here are delivery devices for delivering one or more implants to the body, and methods of using. The delivery devices may deliver implants to a variety of locations within the body, for a number of different uses. In some variations, the delivery devices have a cannula with one or more curved sections. In some variations, a pusher may be used to release one or more implants from the cannula. In some variations, one or more of the released implants may be a self-expanding device. Methods of delivering implants to one or more sinus cavities are also described here.
1. A method of treating one or more sinus cavities comprising:
crimping a device from an expanded diameter to a compressed diameter, wherein the ratio of the expanded diameter to the compressed diameter is about 10:1;
advancing the device in the compressed diameter adjacent to a sinus cavity, wherein the device comprises a polymer at least partially coated with a drug eluting layer, the device degradable over a predetermined period of time and formed into a shape having a series of peaks and valleys, wherein at least one of the peaks and valleys have a loop at an end thereof, wherein the loop comprises a wound polymer filament; and
expanding the device at least partially within the sinus cavity, wherein the device self-expands into contact with surrounding tissue to hold the device in place.
2. The method of claim 1 , wherein the device is advanced adjacent to the sinus cavity in a compressed configuration.
