  • Patent number: 9649650
    Abstract: A device for mixing and dispensing fluids has first and second walls that form a chamber connected to a nozzle. Inlets each configured to receive one fluid are arranged in the first wall. Proximate edges of the inlets are an equal distance from a central point on the first wall. A seal having top and bottom surfaces and a center through hole is positioned in the chamber. The center hole is substantially aligned with the central point. A surface area of the top surface is greater than a sum of the sectional areas of the inlets. A dispensing pump moves the seal between a sealed position in which the bottom surface seals the inlets and an open position in which the bottom surface is spaced away from the inlets to open the inlets to draw the fluids into the chamber to form the mixture for dispensing through the nozzle.

  • Patent number: 9180476
    Abstract: 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.

  • Patent number: 8419623
    Abstract: Disclosed herein is a portable endoscope and kit for performing multiple medical procedures. The portable endoscope comprises a detachable operator control section assembly and one of multiple detachable and interchangeable flexible insertion shaft assemblies with a flexible distal end. The proximal end of a detachable and interchangeable flexible insertion shaft assembly is detachably connected to the detachable operator control section assembly. The detachable and interchangeable flexible insertion shaft assembly accommodates principal cable wires, proxy cable wires, an optical imaging system, and an illumination system. An internal cable wire control system integrated with the detachable operator control section assembly utilizes an adaptable drive transmission system for controlling the orientation and angular position of the flexible distal end using the principal cable wires or the proxy cable wires. The proxy cable wires may be engaged in an event of failure of the principal cable wires.

  • Patent number: 8152808
    Abstract: 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.

  • Patent number: 8109935
    Abstract: 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.
