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.

An intervertebral fusion device includes a structural ceramic body. The structural ceramic body has a bottom surface, a top surface, a peripheral surface connected between the bottom surface and the top surface, and at least one pore channel penetrating the bottom surface and the top surface. The inner surface of the pore channel is either a convex curved surface or a funnel-shaped surface. For the pore channel having the convex curved surface, the pore diameter of the pore channel gradually expands from the center of the pore channel to the top surface and the bottom surface. The pore diameter can also gradually expand from the bottom surface to the top surface. The peripheral surface of the structural ceramic body is wavy or zigzag.

The present disclosure relates to an implant component (10, 20) having at least one connecting portion (30, 60), the connecting portion being at least partly coated with a Zr coating and the coating having a thickness of 1-20 μm, preferably 1-6 μm. The present disclosure further relates to a modular endoprosthesis comprising an implant component, to the use of a Zr coating to prevent crevice corrosion and/or fretting corrosion, and to the use of an implant component in patients suffering from a metal allergy.

Provided are orthopedic implants and systems and kits containing orthopedic implants that include biodegradable polymer thin films containing an antimicrobial agent, wherein the implants produce an effective zone of inhibition around a periphery of the surface of the implant and do not produce a loss of release torque between interlocking implant components.
