Abstract: Described here are devices and methods for crimping self-expanding devices. The crimping devices may be useful for crimping a variety of different self-expanding devices (whether such devices are biodegradable or bio-durable). The crimping devices may have crimping members to engage the self-expanding device to reduce the device from an expanding configuration to an unexpanded configuration. The crimping member may comprise or include a suture, wire, ribbon, guiding hoop, pusher, prong, holding bar, balloon, jaws, combinations thereof, or the like. The crimping devices may also include or comprise a holding structure to hold the self-expanding device in an unexpanded or expanded configuration.

Abstract: 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.

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.
