Abstract: Gymnastic apparatus of the type known as "uneven or asymmetric" bars having two working bars which are parallel to each other but of uneven height wherein the pairs of corresponding ends of the working bars are coupled together by link rods or bars which are preferably telescopic, each of the link rods or bars incorporating length adjustment means operable to effect length adjustment of the link bar and in turn adjustment of the spacing or width between the working bars.

Abstract: A universal anterior chamber lens having an optic with bores entering into the edge of the optic at points spaced circumferentially apart about 180.degree.. The optic is supported in the anterior chamber by haptics, each of which have a first end fixed to the optic, a first leg extending from the optic to the peripheral anatomy of the eye, a second leg extending transverse to the optic in contact with the anatomy of the eye and a third leg extending back toward the optic. The first leg includes a concave spring-like section extending toward the third leg. The free end of the third leg extends into the bore provided in the optic so that as the haptics compress, the free end of the haptic can ride freely in the optic bore. A locking mechanism holds the free end of the haptic in the bore.

Abstract: A total shoulder replacement arthroplasty system which encompasses replacement of the articular surface of the humerus and adjacent glenoid articular surface with a humeral component having a convex surface and a shallow trapezoidal fixation keel to avoid violation of the medullary cavity by the prosthesis and with a concave overmounted glenoid component having a similar keel. The inferior aspect of the acromion is resurfaced with an acromial component for replacement of the acromial clavicular joint, providing mechanical advantage of a fulcrum for abduction and forward flexion of the humerus, and preventing superior migration of the humerus.

Abstract: A physical-rehabilitation and exercise apparatus designed to aid in rehabilitating disabled individuals, particularly stroke victims who have been partially paralyzed. The apparatus is defined by a frame structure having an adjustable seat which incorporates individually operable right and left arm-control actuators, and right and left leg-control actuators. The arm-control actuators together with the leg-control actuators are adjustably slidable so as to provide a reciprocal longitudinal action which is determined by the proper selection of valves within a hydraulic system that includes a plurality of cylinders, each being integrally formed as part of the respective arm and leg control actuators, whereby a series of sequential operations can be selected by the user to provide the necessary movement for exercising the disabled limb or limbs.

Abstract: A two-position pivot support structure is disclosed for enabling a tiltable body exerciser to be tilted about a first or a second horizontally extending pivot axis, the first and second horizontally extending pivot axes being laterally spaced apart. The support structure includes an A-frame stand having left and right pairs of leg members mechanically intercoupled and mounting left and right trunion supporting plates. A first pair of left and right U-shaped trunion receiving slots and a second pair of left and right U-shaped trunion receiving slots are located, respectively, in the left and right trunion supporting plates. A stop member is mechanically joined between the front legs of the A-stand. With the left and right trunions of the tiltable body exerciser positioned, respectively, in the first pair of left and right trunion receiving slots, the tiltable body exerciser is operable to tilt the human body in an inclined, inverted and unlocked body position.

Abstract: An exercise device is provided which is useful for a wide variety of exercises. The exercise device includes a frame and a plurality of weights stacked one above the other on the frame. A lift assembly is slidably mounted on the frame for vertical up and down movement along the height of the frame. The lift assembly includes a cage open at the top and bottom having a sufficient horizontal cross section so that the cage can be moved up and down around the outside of the stack of weights. A first elongated lifting arm extends horizontally along one side of the cage and is mounted to the cage for horizontal sliding movement along the side of the cage. A second elongated lifting arm extends horizontally along the opposite side of the cage and is mounted to the cage for horizontal sliding movement along the side of the cage. Means are on the frame for coupling a selected number of the weights to the lift assembly to thereby provide a resistance force to vertical upward movement of the lift assembly.

Abstract: In the replacement of the lens of an eye, the lens is removed from its natural capsule to leave the capsule intact and a curable polymer composition is injected into the lens capsule where the composition cures to form in sitre a solid, synthetic lens which is optically clear and allows the eye to function.

Abstract: An exercise dumbbell of the type comprising a central grip portion and a pair of weighted bells on each end of the grip portion, wherein each of the bells comprises a soft, pliable outer covering filled with a yieldable mass of weighting material, and wherein the dumbbell comprises an axial support means extending axially of the grip. Preferably the support means is in the form of a rod, solid or hollow, and the end bells, as well as the supporting rod if hollow, are preferably filled with a yieldable mass of weighting material such as small balls or shot, a liquid or a gelatin, or a heavy liquid or gelatin with or without metal particles or pieces dispersed through it.

Abstract: A mammary prosthesis comprising an envelope of an inert elastomer for containing an inert fluid material. The envelope is composed of a plurality of firm protuberances distributed substantially equally thereover. These protuberances may be platelike, ridges, tubes, or posts. The protuberances may be in one or more layers and may be covered with an outer envelope of inert elastomer which may be perforated or in the form of a web. The protuberances provide therebetween flow spaces such that when the scar capsule contracts and compresses the protuberances, the mammary prosthesis will have a space for displacement and remain soft. The protuberances further provide greater localized pressure in pounds per square inch against the scar capsule for a given amount of massage exercise done after surgery. Since scar stretches in response to pressure, this reduces the amount of scar contracture of the capsule.

Abstract: A body-supporting bed pivotally supported on a frame and juxtaposed circular plates controlling pivoting of the bed by a series of locking openings in a first plate, by a locking pin on a second plate, and by an abutment pin on a third plate disposed in arcuate slots in the first and second plates. A foot-supporting boom supported to extend an adjustable distance from the foot of the bed and a pair of adjustable spaced padded ankle-securing tubes on the end of the boom and a latch for the tubes including a push rod operated latch piece, the push rod having a knob disposed between the legs of the user.

Abstract: An external, self-contained laryngeal prosthesis is adapted for use by a tracheostomized patient having a surgically-formed "pseudoglottis" separating the trachea and the hypopharynx. The prosthesis includes a housing and a fitting for attaching the housing to the tracheostoma formed in the patient's neck. The housing contains an inhalation valve to allow inhaled air to pass through a first conduit into the trachea, and an exhalation valve for directing exhaled air from the first conduit into the housing downstream from the inhalation valve toward a second conduit. The second conduit is adapted for communicating between the housing and the hypopharynx through the fitting and through an incision in the pseudoglottis. Downstream from the exhalation valve is a tone-generating mechanism responsive to air pressures in a range normally produced by a speech effort.
