  • DEVICE FOR MIXING AND DELIVERING FLUIDS FOR TISSUE REPAIR
    Publication number: 20130231609
    Abstract: A device for mixing and delivering a mixture of fluids to a target site includes a tube for containing the mixture. A compressible auger for mixing the fluids is movably disposed within the tube, one end of the auger being free at the distal end of the tube. A plunger is also movable within the tube in communication with the other end of the auger. When the plunger is moved axially within the tube the auger also moves axially and the auger is compressed to dispense the fluid. The mixing and delivery device can be used with an apparatus for the arthroscopic delivery of a tissue repair material to a repair site. The apparatus includes a first sheath and a second sheath removably attached to the first sheath for delivering the tissue repair material to the repair site.
