A tympanic membrane prosthesis includes a tubular body having a lumen extending therethrough and open at each of a proximal and distal end. The tubular body forms a structurally self-supporting, body compatible, and body absorbable device. The device is formed of a composite structure that includes an inner portion having an inside surface and an outer portion having an outside surface. The inside surface forms at least a portion of the lumen extending through the tubular body. The inside surface is adapted to provide less resistance to fluid flow than the outside surface. The outside surface is adapted to produce an inflammatory reaction in adjacent tissue at a tympanic membrane. The device is adapted for insertion into an opening through the tympanic membrane for placement with the proximal end and the distal end disposed on opposite sides of the tympanic membrane.

This disclosure describes, inter alia, materials, devices, kits and methods that may be used to treat chronic sinusitis.

The present invention relates to the preparation of a membrane for use in the repair of the middle ear including perforations and damage to the tympanic membrane. More particularly, the invention provides for compositions and methods for preparing silk fibroin biocompatible polyurethane membranes using a solvent, which have improved biodegradation, mechanical and vibroacoustic properties.

A nasal implant delivery tool includes an inner handle, an outer handle, a needle, and a push rod. The inner handle includes a loading chamber configured to receive a nasal implant. The outer handle is configured to move axially relative to the inner handle. The needle extends distally from the inner handle and has a central lumen and a distal opening. The push rod is configured to move the nasal implant from the loading chamber, through the central lumen, and out the distal opening of the needle. The push rod is coupled to the outer handle such that the push rod moves axially relative to the inner handle when the outer handle is moved axially relative to the inner handle. Also described herein are nasal implant guides and methods of using nasal implant delivery tools and nasal implant guides.

The technology involves scaffold structures used for in-ear sensor systems. Such systems that can perform biometric signal detection or act as a human-computer interface. Scaffolding arrangements minimize the amount of material placed in the ear while providing a secure fitting device that can be worn for hours, days or longer in order to provide maximal benefit to the wearer. The scaffolding includes a “C”-shaped arcuate curvature for at least part of the housing. This configuration can act as a natural leaf spring to help maintain the housing in contact with different points along the ear. Sensors are located along various points of the scaffolding for use in different diagnostic situations. Different components of an on-board sensor input and processing system can be distributed along different parts of the scaffolding. Such structures beneficially minimize ambient sound occlusion and avoid the need of an exterior strap or clip worn around the ear.
