Embodiment Construction

[0014] Embodiment aspects described herein relate to systems, methods, and instruments for irrigating the frontal sinus region of a patient. In some cases, aspects of the invention are used for one or more of the following: reducing, removing, or preventing the growth of bacterial biofilms.

[0015] Considering the above, Figure 1A A surgical frontal sinus irrigation system 20 is shown, according to some embodiments, and used, for example, to remove bacterial biofilms. The system 20 includes a surgical irrigation instrument 22 , an irrigation source 24 and a controller 26 . In general, irrigation source 24 provides fluid or irrigation to instrument 22, eg, via supply conduit 28 (eg, tubing). The controller 26 controls operational aspects of the system 20 and is shown generally associated with the instrument 22 and irrigation source 24 .

[0016] System 20 may include additional components. For example, another frontal sinus irrigation system 20' is shown in Figure 1B , a...

Abstract

A surgical instrument (22) for irrigating a frontal sinus target site of a patient including a handle, an introducer (42), an irrigation channel (60), a nozzle (44), and an actuator assembly (46). The introducer extends from the handle and defines a proximal segment and a distal segment. At least a portion of the proximal segment (110) is rigid and linear and at least a portion ofthe distal segment (112) is rigid and relatively curved. The nozzle is fluidly connected to the irrigation channel, and is rotatably maintained at a distal end (114) of the introducer. The actuator assembly includes an actuator (140) 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 aduit.

Description

technical field [0001] The present invention relates to systems and methods for delivering irrigants to the frontal sinus of a patient. More particularly, it relates to systems and methods for surgical treatment of the frontal sinuses, such as removal of bacterial biofilms. Background technique [0002] Bacterial biofilms develop in various body cavities including, for example, ear cavities such as the middle ear, and nasal cavities such as the frontal or maxillary sinuses. Once bacterial growth has established, the bacteria will typically aggregate, stop dividing and begin to form a protective bacterial biofilm layer or "slime layer" composed of polysaccharide material. [0003] Protective bacterial biofilms interfere with the body's natural immune response as well as traditional treatments. Specifically, the bacteria produce exotoxins, which stimulate the body's immune system to respond to white blood cells. However, bacterial biofilms affect the efficiency of white blo...
