Abstract
Described here are self-expanding devices and methods of using and making them. The devices may be useful in a variety of locations within the body, for a number of different uses. In some variations, the devices have a first compressed configuration enabling low profile delivery through a delivery device, a second expanded configuration for apposition against tissue, and comprise either a single continuous filament or at least two non-intersecting filaments. In some variations, the device is formed into a shape having a series of peaks and valleys. At least one of the peaks and valleys may have a loop at then end thereof. At least a portion of these devices may be capable of biodegrading over a predetermined period of time, and the devices may be configured for drug delivery. Methods of treating one or more sinus cavities are also described here.
