Patent number: 9326665Abstract: 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.Type: GrantFiled: April 9, 2007Date of Patent: May 3, 2016Assignee: Medtronic Xomed, Inc.Inventors: Dale E.

Patent number: 8313489Abstract: 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.Type: GrantFiled: August 9, 2010Date of Patent: November 20, 2012Assignee: Medtronic Xomed, Inc.Inventors: Kenneth M.
