An exercise machine or dynamometer is provided with control apparatus for ascertaining the physical position of a patient during an exercise. The patient is then electrically stimulated over selected ranges of motion in order to aid in the exercise.

A method and apparatus for treating ear infections in which a straight linear path is established from an external position to a specific target site on the eardrum. Thereafter a laser beam is caused to be emitted along the established path to impinge upon the eardrum to create a hole at the target site. Immediately thereafter, a hollow, tubular drainage missile is caused to be projected along the same established path into the hole formed at the target site to seat therein. The missile maintain...

A method and apparatus for evaluating of implanted artificial (mechanical or bioprosthetic) heart valves includes a microprocessor responsive to a series of digital signals for processing a portion of the series of digital signals corresponding to valve sounds in a phonocardiogram. A deconvolution algorithm is provided to transform the portion of the series of digital signals into an impact history signal which characterizes the motion of the occluding elements and an impulse response signal. A ...

A laser coagulation system projects a slit image beam into an eyeball to determine a treatment point and selectively delivers argon and krypton laser beams thereto during an opthalmological operation. Observation equipment receives the slit image beam and laser beams reflected from the treatment point to observe the treatment point. A pair of discs are coaxially rotatably mounted around a shaft parallel to the optical axis between the treatment point and the observation equipment. The discs are ...

A fluid submersible laryngoscope includes a hollow handle to contain a power supply such as dry cell means. A light source is carried by the handle, and structure is provided to place that power supply in electrical energy transmitting relation with that light source to direct light into transmitting means carried by the blade. The blade is insertible into a patient's mouth to illuminate the throat area. Sealing structure is provided between the terminal light source and handle to block access o...

A hand piece for use with a laser includes a scanning mechanism which controls dosimetry of radiation applied to a target area which is adjustable to limit thermal diffusion from the light absorbing portion of the irradiated target site for selective target specific energy deposition. When used for dermatologic purposes, the adjustable scanning mechanism permits radiation to impinge on tissue for a predetermined period of time for the selective necrosis of highly-filled blood vessels, while leav...

A gastrointestinal diagnostic capsule that includes an encapsulated expandable foam material introduced through the oral cavity and through the esophagus into the stomach with the capsule being dissolved by the temperature and moisture conditions encountered so that the foam block or cube can expand in the stomach and be withdrawn through the gastroesophageal junction and up through the entire esophagus to obtain specimen material for diagnostic procedures for early detection of gastroesophageal...

A high-frequency incision tool has a flexible sheath which is adapted to be inserted into the body cavity along with an endoscope. A suction port is formed at the distal end of the sheath. A wire is inserted into the sheath and a part of the wire is exposed from the sheath to form an incision section. The wire is pushed and pulled by an operating section which is provided at the proximal end of the sheath. A suction mouthpiece is formed at the operating section to communicate with the suction po...

A depilatory device for removing body hair, comprises a manually-grippable housing, and a hair-plucker body rotatably mounted to the housing and having an exposed section formed with a plurality of gaps in its outer surface which open and close during the rotation of the hair-plucker body to receive, pluck, and eject body hair growing on a surface over which the hair-plucker body is moved. The hair-plucker body is a flexible cylindrical member of plastic on elastomeric material having a smooth o...

A resectoscope device comprises a sheath body having an elongated hollow sheath to be inserted into a urethra. A handle part has a slider connected to the sheath body and slides in the axial direction. An observing scope is inserted into the sheath through the handle part and sheath body. An electrode is inserted through the sheath, and is removably connected at the rear end to the slider. The electrode has a resecting part that can be projected out of and retreated into a beak opening at the ti...
