Systems and methods for deploying a stent within the frontal sinus. The stent includes flexible foam and film layers arranged in a stacked configuration and furled within a cartridge prior to deployment. The cartridge is removably coupled to an applicator device including an actuator. The film layer may include a polymer having a resilience sufficient to unfurl the stent and maintain patency of the frontal sinus opening. The flexible foam layer may have porosity of greater than 80%, and an active agent may be within the flexible foam layer. The flexible foam layer may be bioresorbable and the flexible film layer biocompatible and non-biodegradable. The stent may include first and second body portions with the first body portion independently unfurling from the second body portion to retain the stent within the frontal sinus. Contouring of the first and second body portions may facilitate ease with removal of the stent.

Described are implants for placing in a body, tools for delivering the implants, and systems and methods for using implants and tools for placing in a body and more particularly to nasal implants, tools for delivering nasal implants, and systems and methods for using such implants and tools. A tool may include a hand-held implant delivery device that holds, moves, orients, inserts, or shapes an implant. An implant may be a biodegradable, longitudinal implant that may be oriented for implantation by an implant delivery device.

Described herein are methods and devices for delivering a drug to the frontal sinus system. An inflatable implant is positioned within the frontal sinus system using an anchoring means secured within the frontal sinus cavity. A drug-containing fluid is released directly into the frontal sinus drainage system.

Earpieces and methods of forming earpieces for radio frequency (RF) mitigation are provided. An earpiece is configured to be inserted in an ear canal. The earpiece includes an insertion element and a sealing section disposed on the insertion element and configured to conform to the ear canal. The sealing section is configured to substantially mitigate radio frequency (RF) transmission and to substantially isolate the ear canal from an ambient environment.

Nasal implants are provided that have a planar type profile with open spaces through portions of the planar type profile. The nasal implant can be compressible along one or more dimensions of the nasal implant, such as the width and length of the planar type profile. Delivery tools for deploying the nasal implants within the nasal tissue are also provided. Methods for deploying the nasal implants within the nasal tissue of the patient are also provided.

Medical devices for repairing defects in tissue, such as perforations in the tympanic membrane of an animal, methods of manufacturing medical devices, methods of implanting a medical device in a defect in a tissue; and methods of repairing a defect in a tissue are described. In one form, a medical device includes an overlay member having multiple arms and defining an overlay member passageway, an underlay member having multiple flaps and defining an underlay member passageway, and a securement member extending through the overlay member passageway and the underlay member passageway. In methods, the multiple flaps of the underlay member can be sequentially advanced into a defect in a tissue, such as a perforation in a tympanic membrane of an animal.

A system includes electronic circuitry that receives a self-clocking differential signal comprising a data signal encoded with a clock signal at a dock frequency. The electronic circuitry is configured to recover, from the self-docking differential signal, the data signal and the dock signal. Then, based on the recovered dock signal, the electronic circuitry is configured to wirelessly transmit, to an implantable stimulator implanted within a recipient, a forward telemetry signal representing data recovered from the data signal. Corresponding systems, methods, devices, and application specific integrated circuits (ASICs) are also disclosed.
