Abstract

Systems, devices, and methods may be used for delivery of an implant to a bodily cavity. The implant may include a hub and a plurality of legs, and may be moveable between a low-profile and expanded configuration. The systems may include a crimping device having a crimping member with a plurality of arms. The plurality of arms may engage the plurality of legs of the implant, and may move the legs to move the implant to the low-profile configuration. In some instances a delivery device may aid in crimping and/or delivery of the implant.

Claims

1. An expandable implant for placement in a sinus or a nasal cavity comprising:

a hub, wherein the hub is formed from a biodegradable copolymer at a first composition ratio and comprises a plurality of apertures extending through the hub, each of said plurality of apertures comprising a first aperture segment and a second aperture segment separated by a hollow interior of the hub; and

a plurality of filaments, wherein each filament of the plurality of filaments is formed from the biodegradable copolymer at a second composition ratio different from the first composition ratio, and wherein each filament of the plurality of filaments is positioned in a corresponding aperture of the plurality of apertures such that a portion of the filament extends through each of the first aperture segment, the second aperture segment, and the hollow interior of the hub to define a first leg on a first side of the hub and a second leg on a second side of the hub, and further wherein the expandable implant is sized and shaped for placement within the sinus or the nasal cavity.

2. The implant of claim 1 wherein each filament comprises a first straight segment, a second straight segment, and a curved segment positioned between the first straight segment and the second straight segment.

3. The implant of claim 2 wherein the curved segment of each filament is positioned in the corresponding aperture to position the first straight segment on the first side of the hub and the second straight segment on the second side of the hub.

4. The implant of claim 1 wherein each filament is an extruded polymer filament.

5. The implant of claim 4 wherein the hub is an injection molded hub.

6. The implant of claim 1 wherein the plurality of filaments are formed from one or more biodegradable materials.

7. The implant of claim 1 further comprising a drug-releasing coating.

8. The implant of claim 1 wherein the plurality of filaments form a plurality of legs having a first length and a second length, the first length being different from the second length.

9. The implant of claim 1 wherein the first length is about 20 mm and the second length is about 25 mm.

10. The implant of claim 1 wherein at least one of the plurality of filaments has a rectangular cross-sectional shape.

11. The implant of claim 1 wherein at least one of the plurality of filaments has an oval cross-sectional shape.

12. The implant of claim 1 wherein at least one of the plurality of filaments has a circular cross-sectional shape.

13. The implant of claim 1 wherein the drug-releasing coating comprises mometasone furoate.
