A magnetically driven pressure generator including a housing, flexible member, first magnetic force generator, and second magnetic force generator. The magnetically driven pressure generator oscillates the flexible member to increase or decrease the volume of a chamber, inversely increasing or decreasing the pressure of the chamber.

An eartip, mold device for manufacturing the eartip, and method of manufacturing the eartip are introduced, characterized by forming an upper bevel-portion with upper and lower molds of a first mold unit, placing the upper bevel-portion in an upper bevel receiving cavity of a second mold unit, forming a lower bevel-portion with a lower bevel cavity, and joining the upper and lower bevel-portions to form an eartip. The top of the lower hollow-cored guiding tube extends to form a buffer portion which connects and communicates with the upper hollow-cored guiding tube. The upper and lower bevel-portions are made of silicone of different rigidity. The upper bevel-portion thus made is soft enough to reach a user's ear canal deeply. The lower bevel-portion thus made is rigid enough to close the ear canal. An annular buffer cavity is inwardly, concavely formed at the bottom of the lower bevel cavity.

The invention relates to a device for the treatment of a tinnitus condition, comprising a pressure point body which is dimensioned so that it can be secured to or in the vicinity of the auricle, characterized in that said pressure point body has a fastening element and a pressure element, whereby the position of the auricle is changed and/or the middle ear is deformed.

A simple hearing enhancement device that takes the normally adequately loud sound levels and optimizes selective frequency gain of the patient's ear passage to improve speech comprehension.

A magnetically driven pressure generator including a housing, flexible member, first magnetic force generator, and second magnetic force generator. The magnetically driven pressure generator oscillates the flexible member to increase or decrease the volume of a chamber, inversely increasing or decreasing the pressure of the chamber.

The application discloses an a method of forming a lower friction eartip when compared to a pretreated elastomer eartip.

A system effectively narrows a patulous Eustachian tube (ET) of a patient with a guide catheter, instrument, and insert. The guide catheter includes a shaft, a lumen and a distal end configured to provide access the ET when the guide catheter is inserted into a head of the patient. The instrument comprises a shaft. The insert comprises a body configured to radially expand and retract between a non-expanded state and an expanded state. The insert is sized and shaped to be received within the first lumen when in the non-expanded state and is operable to expand to the expanded state to substantially reduce an effective diameter of the ET.
