摘要： A balloon is provided for insertion into a mammalian eustachian tube. The balloon is a high pressure balloon having a body including a proximal end, a distal end, an exterior surface and an interior surface defining an air receivable interior. The body having a plurality of segments of different cross sectional areas, and a non-circular cross sectional profile. The balloon is inflatable between a deflated configuration and an inflated configuration. The body is sufficiently inelastic so as to be substantially incapable of expanding beyond a pre-determined size and shape when in the inflated configuration. The segments include a first segment having a first cross sectional area and a second segment disposed distally of the first segment The second segment has a second cross sectional area larger than the first cross sectional area.

摘要： The hearing aid apparatus includes a first hearing aid member and a second hearing aid member. The first hearing aid member is placeable on a patient's body, and includes a first transducer for receiving sounds that would be received by the patient's first ear and converting these received sounds into first transmittable signals. The second hearing aid is placeable on a patient's body adjacent to the patient's second ear, and includes a receiver for receiving the first transmittable electrical signals and a second transducer for converting the first transmittable electrical signals into sound signals configured for delivery to the patient's second ear.

摘要： A tympanostomy tube for insertion into and residence in a tympanic membrane of a mammal, is disclosed. The tympanostomy tube includes a body including a first end portion, a second end portion, a central portion dispensed between the first and second end portions. An axially extending passageway has a first open end disposed adjacent the first end portion, and a second open end disposed adjacent the second end portion, and an axis extending between the first open end and second open end. The first end portion includes a relatively enlarged diameter, generally radially extending flange. The central portion includes a reduced diameter portion sized for extending through and residing in tissue of the tympanic membrane. The second end portion includes a relatively enlarged diameter second flange disposed adjacent the second end portion. The second flange includes a perimetral edge having an incising portion sufficiently sharpened to cut as a knife through the tympanic membrane during insertion of the tympanostomy tube in the tympanic membrane.
