Abstract

Described here are systems, devices, and methods 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. A system for treating one or more conditions comprising:

an implant comprising a hub and a plurality of filaments, wherein the hub comprises a plurality of apertures extending through the hub and wherein each filament of the plurality of filaments is positioned in a corresponding aperture of the plurality of apertures to extend through 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

a crimping device comprising a housing, the housing comprising a recess and a plurality of channels radially extending from the recess, and wherein movement of the hub into the recess rotates the first and second legs toward a longitudinal axis of the implant to move the implant to a low-profile configuration.

2. The system of claim 1 wherein the crimping device further comprises a crimping member, wherein the crimping member comprises a plurality of arms radially extending from a stem portion, and wherein movement of the stem portion into the recess rotates the plurality of arms relative to the stem portion.

3. The system of claim 1 further comprising a delivery device configured to releasably couple to the implant.

4. A method for treating one or more sinus conditions comprising:

advancing an implant to a location in a sinus cavity, sinus ostium or nasal passageway, the implant comprising a hub and a plurality of filaments, wherein the hub comprises a plurality of apertures extending through the hub and wherein each filament of the plurality of filaments is positioned in a corresponding aperture of the plurality of apertures to extend through the hub to define a first leg on a first side of the hub and a second leg on the second side of the hub;

delivering the implant; and

expanding the implant from a low-profile configuration to an expanded configuration.

5. The method of claim 4 further comprising crimping the implant to move the implant to the low-profile configuration.
