20080215052 | Allograft implant workstation - The invention is directed toward a portable surgical workstation for implant formation comprising a base with a central planar section with integral handles extending from the central planar section at an angle to the plane of the central planar section. The central planar section has a plurality of tracks and a throughgoing slot with a recessed stepped surrounding surface formed on a bottom surface of the central planar section. A vise assembly mounted to the base and comprises a fixed jaw member secured to the base, a traveling jaw member moveably mounted to the base and a fixed drive housing mounted to the base. The traveling jaw member has a plurality of rail members adapted to be slidably mounted in the central planar section tracks. The fixed drive housing has a threaded longitudinal bore which receives a threaded drive shaft, one end of the drive shaft being secured in the traveling jaw member to preclude axial movement of the drive shaft within the traveling jaw member while retaining rotational movement to transport the traveling jaw members toward and away from the fixed jaw member. | 09-04-2008 |
20080255623 | Osteochondral allograft cartilage transplant workstation - The invention is directed toward a portable surgical workstation and kit of accessory devises for cartilage implant formation comprising a base, a vise assembly mounted to the base, the vise assembly comprising a fixed jaw member and a moveable jaw member, each jaw member defining grasping surfaces for holding a bone workpiece. A shaft drive is threadably connected to the moveable jaw member and rotatably mounted in the fixed jaw member for transporting the moveable jaw toward and away from the fixed jaw. An articulated guide assembly is mounted to the fixed jaw member, the articulated guide means including a sleeve member and a plurality of moveable interconnected members selectively rotatable on a ball joint. A miter assembly defining a slot of a width to receive a surgical saw is mounted to at least one of the jaw members. The kit of accessory devices comprises a plurality of different diameter bushings which fit in the sleeve member and a plurality of different diameter cylindrical core cutter assemblies sized to fit in each respective sized bushing and a donor cutter guide adapted to fit in said sleeve. | 10-16-2008 |
20090299371 | Surgical bone cutting assembly and method of using same - The invention is directed toward a surgical kit having component parts capable of use in excising a cartilage defect site on a patient to prepare the same for receipt of an implant plug, the kit comprising a cylindrical gauge with a central bore used to measure the defect area, a guide rod adapted to be driven through the gauge tube into the center of said defect area and a cartilage cutting assembly adapted to be mounted over the guide rod and used for excising the defect area and cutting a cylindrical bore into the defect area. The method for use of the kit comprises the steps of: marking the defect area to be cut; placing a guide rod into the center defect area and driving the same to a predetermined distance to secure the same in the defect area and placing a drill bit over the guide rod and rotating the drill bit to cut a cylindrical blind bore removing the cartilage defect. | 12-03-2009 |
20090299372 | Surgical allograft bone plug cutting tool assembly and method of using same - The invention is directed toward a surgical kit having component parts capable of use to prepare a cartilage implant plug from allograft condyle. The kit comprises a sizing gauge used to measure surface of the allograft condyle so that a cartilage implant plug can be removed that corresponds to the contours of the defect site excised on a patient. An adjustable guide member is mounted in a fixed orientation over the allograft condyle in which a cylindrical graft cutter for cutting a cylindrical allograft bone plug having a cartilage cap and a bone end portion. A chamfering tool is used for chamfering the bone end of the allograft bone plug. | 12-03-2009 |
20100098280 | Hearing aid - A hearing aid includes a circuit board having a battery affixed thereon and a switch that utilizes a portion of the circuit board as a portion of the switch. The battery is permanently affixed to the circuit board in at least one location and at least a portion of the battery is spaced away from the circuit board. The circuit board further includes at least one pair of printed switch traces. The switch is integrated into the circuit board in a way that utilizes the circuit board to form a rotary switch. | 04-22-2010 |
20100119094 | Hearing aid - A hearing aid includes a hearing aid shell, a microphone enclosed within the hearing aid shell, and a sealing member that surrounds the periphery of the microphone enclosed within the hearing aid shell, and a sealing member that surrounds the periphery of the microphone. The sealing member completely fills the area between the periphery of the microphone and the interior surface of the hearing aid shell. | 05-13-2010 |
20100292704 | IMPLANT INSERTER DEVICE - An implant inserter device having an outer collar, an inner sleeve slidably and rotatably received within the outer collar, and a push rod slidably received within the inner sleeve. The outer collar has at least one cammed surface formed on an interior surface thereof, while the inner sleeve has at least one rib projecting outwardly from an exterior surface thereof. The rib is releasably engageable with the cammed surface when the inner sleeve is rotated relative to the outer collar. As a result, a distal end of the inner sleeve collapses from an undeformed position, in which the inner sleeve does not grip an implant housed therein, and a deformed position, in which the inner sleeve grips the implant. The push rod is movable between an extended position and a retracted position for urging the implant through and from the inner sleeve for insertion into a defect in damaged cartilage and bone. | 11-18-2010 |
20120279990 | MIXING AND DISPENSING DEVICE - A device for dispensing a mixture of at least two fluids is disclosed. The device has a plurality of cartridges that each contain a fluid. A flow channel communicates with each cartridge. A valve adjusts a mass flow rate of the fluid drawn from the corresponding cartridge. A manifold has a mixing chamber and a plurality of inlets that each communicate with one of the flow channels. The manifold has a spring and a seal that covers the inlets. A piston is between the seal and the spring. The spring is moveable between an extended position that positions the seal to substantially and simultaneously close the inlets from the flow channels and a compressed position that positions the seal to substantially and simultaneously open the inlets to the flow channels. A dispensing pump communicates with the manifold and draws fluid from each of the cartridges. A nozzle dispenses the mixture. | 11-08-2012 |
