  • Patent number: 9326665
    Abstract: Systems and methods for removal of bacterial biofilm from a target site of a human patient includes a surgical instrument having an introducer for bodily insertion and maintaining an irrigation duct and a nozzle. A distal portion of the introducer is transitionable between a plurality of bend angles relative to a proximal portion thereof. In particular, the instrument is adapted to independently maintain the distal portion at each of the plurality of bend angles relative to the proximal portion. The nozzle is maintained relative to the distal portion of the introducer and is adapted to dispense pressurized irrigant from the irrigation duct toward a layer of bacterial biofilm.

  • Patent number: 8313489
    Abstract: A surgical micro-burring instrument including an outer tubular member coaxially maintaining an inner tubular member. The outer tubular member defines a proximal section, a distal section, and a central lumen extending from the proximal section to the distal section. The distal section forms a pocket and an elevator tip. The pocket has a bottom wall and an opposed upper opening. The elevator tip extends distal the pocket. The inner tubular member forms a bur received within the pocket. Upon final assembly, at least a portion of the bur is exposed relative to the outer tubular member via the upper opening of the pocket. The elevator tip is configured to facilitate lifting of soft tissue, such as mucosa, while positioning the bur, via the pocket, in an appropriate location for cutting contacted harder tissue, such as turbinate bone or septal bone/cartilage.

  • Patent number: 8172846
    Abstract: A method for performing a surgical procedure on tissue at a target site of a patient includes providing a surgical cutting instrument including an outer tube, inner wire assembly and a cutting tip. The outer tube defines a curved segment. The inner wire assembly is rotatably disposed within the outer tube. The cutting tip is connected to the inner wire assembly and positioned at a distal end of the outer tube. The tissue at the target site is exposed and the cutting tip is deployed against the tissue. The method further includes rotating the inner wire assembly relative to the outer tube at speeds in excess of 50,000 RPM such that the cutting tip removes contacted tissue.

  • Patent number: 7488322
    Abstract: A surgical cutting instrument including an outer tube, inner wire assembly, cutting tip, coupling chuck, and housing. The outer tube includes a lumen extending from a proximal end to a distal end. The inner wire assembly is received within the lumen. Preferably, the outer tube and inner wire assembly form a longitudinally curved segment. The cutting tip is connected to a distal section of the inner wire assembly. The coupling chuck is secured to a proximal section of the inner wire assembly. The housing maintains the outer tube and the coupling chuck. A rotating journal bearing, preferably a rotating-hydrodynamic bearing, is established between the inner wire assembly and the inner surface of the outer tube, allowing nominal rotational speeds of 80,000 RPM. Preferred embodiments of the surgical cutting instrument enhance surgeon visibility, minimize heat build-up, and provide improved stiffness and thermal protection.
