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.

La présente invention concerne des dispositifs auto-expansibles et leurs procédés de fabrication et d'utilisation. Les dispositifs peuvent être utiles dans divers endroits du corps pour un certain nombre d'utilisations différentes. Dans certaines variantes, les dispositifs prennent une première configuration comprimée permettant une mise en place discrète par un dispositif de mise en place, et une seconde configuration dilatée permettant une apposition contre un tissu. Ils comprennent soit un seul filament continu, soit au moins deux filaments ne se croisant pas. Dans certaines variantes, le dispositif a la forme d'une série de pics et de vallées. L'extrémité d'au moins un des pics et des vallées peut comprendre une boucle. Au moins une partie de ces dispositifs peut être capable de se biodégrader sur une période prédéterminée et les dispositifs peuvent être configurés pour l'apport de médicaments. L'invention concerne également des procédés de traitement d'un ou plusieurs sinus.
