Appl. No.:

12/111804

Inventors:

Isaac C. Perry - Jacksonville FL, US

International Classification:

A61M 1/00
A61M 31/00
A61B 1/00

US Classification:

604 35, 604 9501, 600146

Abstract:

A surgical instrument for irrigating a frontal sinus target site of a patient including a handle, an introducer, an irrigation channel, a nozzle, and an actuator assembly. The introducer extends from the handle and defines a proximal segment and a distal segment. At least a portion of the proximal segment is linear and at least a portion of the distal segment is relatively curved. The nozzle is fluidly connected to the irrigation channel, and is rotatably maintained at a distal end of the introducer. The actuator assembly includes an actuator maintained by the handle and connected to the nozzle. Movement of the actuator causes the nozzle to rotate relative to the introducer. The introducer can be sized and shaped in accordance with a size and shape of the nasal passageway/frontal sinus of a human adult.

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.
