Ear implants for auricular tissue reconstruction in a patient are provided. The ear implant may be a tissue scaffold multicomponent assembly for reconstruction of auricular tissue. Thus, the assembly may include both a first and a second tissue scaffold component. Each comprises a biocompatible polymeric material having a plurality of open pores configured to support cell growth. The first tissue scaffold component defines a central void region and at least a portion of an outer ear framework of the patient after implantation. The second tissue scaffold component defines a base portion. After implantation into the patient, the second tissue scaffold component seats within the central void region of the first tissue scaffold component, so that the second tissue scaffold component is secured to the first tissue scaffold component. Methods for reconstructing auricular tissue in a patient using such ear implant tissue scaffolds are also provided.

The present disclosure relates to a method for manufacturing nose implant, including obtaining a 3-dimensional image of a nasal bone and a 3-dimensional image of a nasal cavity; modeling a nasal cartilage by applying information of anatomy between the nasal bone, nasal cavity, and nasal cartilage, to the 3-dimensional image of the nasal bone and the 3-dimensional image of the nasal cavity; and modeling an inner shape of where the implant may be seated, from the 3-dimensional image of the nasal bone and the modelled nasal cartilage.

Cartilage support implants for nasal valve support and delivery systems are described. The cartilage support implant can include one or more elongate bodies comprising one or more anchors. The cartilage support implant can be designed to be a permanent implant extending along the midline of a patient's nose, from the nasal bone to the lower lateral cartilage. Methods of placing the cartilage support implant and retrieving the cartilage support implant are also described.

A device includes an electromagnetic radiation delivery system such as a laser of light emitting diode infrared emitter configured for delivery of electromagnetic radiation within a sealed canal such as an ear canal, a fiber optic cable configured for delivering or capturing the electromagnetic radiation within the sealed canal, and a photo detector coupled to the fiber optic cable forming a portion of a voice communication system. Other embodiments are disclosed.

This application relates to a stent inserted in an eustachian tube for treatment of eustachian tube dysfunction. In one aspect, the stent includes a pressure controller which blocks the eustachian tube and is opened/closed according to a pressure difference between front and rear portions thereof to control a pressure in the eustachian tube. The stent may also include a eustachian tube expansion portion which is connected to the pressure controller and has a hollow portion passed therein to make a fluid move in back and forth directions of the eustachian tube, and is inserted in the eustachian tube to expand the eustachian tube by transforming a shape thereof in a radial direction of the eustachian tube.

Disclosed are a biological tissue matrix material, a preparation method therefor and the use thereof in an otological repair material. The biological tissue matrix material comprises an extracellular matrix. The extracellular matrix comprises a collagen fiber, a growth factor and fibronectin. The biological tissue matrix material has a low amount of DNA residue, a low immunogenicity, a high anti-infection ability, and a strong repair capability.

Sinusitis and other disorders of the ear, nose and throat are diagnosed and/or treated using minimally invasive approaches with flexible or rigid instruments. Various methods and devices are used for remodeling or changing the shape, size or configuration of a sinus ostium or duct or other anatomical structure in the ear, nose or throat; implanting a device, cells or tissues; removing matter from the ear, nose or throat; delivering diagnostic or therapeutic substances or performing other diagnostic or therapeutic procedures. Introducing devices (e.g., guide catheters, tubes, guidewires, elongate probes, other elongate members) may be used to facilitate insertion of working devices (e.g. catheters e.g. balloon catheters, guidewires, tissue cutting or remodeling devices, devices for implanting elements like stents, electrosurgical devices, energy emitting devices, devices for delivering diagnostic or therapeutic agents, substance delivery implants, scopes etc.) into the paranasal sinuses or other structures in the ear, nose or throat.
