Abstract:
A medical ventilation tube for placement in an opening formed in an anatomical structure, such as the tympanic membrane of the ear, includes a hollow tubular shaft made of a first material having a hardness or durometer to maintain a passage through the shaft when the medical ventilation tube is placed in the opening, and a flange made of a second material having a hardness or durometer less than that of the first material to permit the flange to deform in response to contact with the anatomical structure during removal of the medical ventilation tube from the opening.
Abstract:
A surgical nasal septum splint comprising a pair of members, each of which having a thin, flat body with a posterior end adapted to be inserted into the nasal passage and to be positionable interiorly thereof and with an anterior end adapted to be positionable adjacent the nasal columella, said body carrying a plurality of spaced magnets, the magnets adjacent the anterior end having a different polarity from the magnets adjacent the posterior end of each body, and the correspondingly positioned magnets in said pair of members being of opposite polarity so as to be attracted to each other when the members are in place on opposite sides of the nasal septum.

Abstract:
Systems and method ablate motor nerve tissue by inserting an operative element connectable to an ablation energy generator into a defined percutaneous tissue region. The systems and methods apply stimulant energy in the defined percutaneous tissue region to stimulate targeted motor nerve tissue prior to ablation by the operative element. Application of the nerve ablation energy can permanently eliminate the function of a targeted motor nerve branch, to thereby inactivate a selected muscle. The muscle inactivation may, e.g., treat dystonias and other hyperfunction neuromuscular dysfunctions in the face and neck, such as torticollis, blepharospasm, and uncontrolled grimacing. The muscle inactivation may also provide cosmetic results, to eliminate or prevent aesthetically displeasing skin furrows, frowning wrinkles, or neck bands, which can arise from normal muscle contraction or prolonged exposure of the face to the sun.
Abstract:
A portable apparatus for immediate self-treatment of sensorineural hearing loss, vertigo, tinnitus and aural fullness includes a probe for establishing a hermetic seal with the ear canal and a pump for establishing a positive or negative pressure in the ear canal via a hose connected to the probe. The portable apparatus further includes special controls accessible only to a physician or audiologist for establishing the maximum pump pressure and duration of operation optimal for the individual patient. The portable apparatus also includes controls accessible to the patient for initiating pump operation and varying the pump pressure and duration of operation within the limits established by the special controls. The apparatus includes its own independent power supply and may be conveniently carried anywhere by the patient so that it is with him at all times. Whenever the patient senses the onset of symptoms associated with sensorineural hearing loss, vertigo, tinnitus or aural fullness, he merely inserts the probe into the afflicted ear and, using the controls, activates the pump.

Abstract:
An acoustical small hearing aid designed to be worn in the concha of the auricle and made of thin-walled plastic, metal, or rubber. This invention modifies the normal conchal resonance and combines it with the ear canal resonance to shift the normal sound pressure gain of 15 to 20 dB at the tympanic membrane downward from 2600-3000 Hz to 1500-2000 Hz dB, or lower, thus providing significant sound amplification for persons with mild high-frequency hearing loss. The invention accomplishes these goals by providing a thin, hollow shell that fits snugly into the auricle and concha of the external ear so as to enclose a volume of air within the concha. An opening in the shell lets sound waves into this air volume. The ratio of the air volume and the area of the opening control the peak frequency of amplification desired, the amplitude, and bandwidth of amplification, and must be kept between 1/2 and 1/15.
Abstract:
The tympanic membrane can be tightened by directing energy on spots of the tympanic membrane so as to heat up the collagen matrix layer and cause it to shrink. Energy in the frequency range of 1.4 to 2.6 microns, which roughly corresponds to a collagen absorption range of from 10 to 150 cm.sup.-1, is used.
Abstract:
A myringotomy ventilation tube for insertion into an opening in the tympanic membrane comprising(a) a tubular body open at both ends;(b) an outer flange secured to one end of the tubular body and having a rod-like tail member extending outwardly from the flange and adapted to be easily grasped by a medical forceps; and(c) two inner flexurally resilient arms secured to the other end of the tubular body and extending laterally in opposite directions respectively from the tubular body and adapted to be squeezed together to form a longitudinal extension of the tubular body when inserted into the tympanic membrane opening.
