    Abstract: A method for differentiating between ultrasonically tuned blades which are broken or cracked, and blades which are gunked by evaluating measured impedance differences. The method is performed irrespective of the age of the hand piece/blade, the temperature or specific type of hand piece or blade, and is not affected by self healing effects of slightly cracked blades. Moreover, the method facilitates the quantifiable determination of the amount of gunk on the blade. Absolute impedance measurements of the transducer or blade are unnecessary. Instead, only relative impedance measurements are required, which greatly simplifies the measuring criteria. This provides a way to measure the amount of gunk accumulation, and thereby a way to calculate/estimate the amount of heat generated at the sheath, as well as a way to calculate/estimate the amounts of degradation to the load curve of the ultrasonic system.

    Abstract: The disposable endoscope sheath includes a low-profile sleeve member that can accommodate a variety of different endoscope lengths that are longer than the sleeve member. In several embodiments of the invention, the sleeve member includes irrigation channels that do not communicate with an endoscope receiving space. In other embodiments of the invention, irrigation fluid passes through the endoscope receiving space of the sleeve member. In all embodiments of the invention, irrigation fluid that is expelled from the sleeve member can flush surgical debris away from the viewing end of the endoscope. The sleeve member has a generally low profile and does not require continuous suction to halt the expulsion of irrigation fluid from the sheath when the irrigation function is not being used. A brief reverse suction can be used to remove a residual drop of cleaning solution from the viewing end of the sheath.

    Abstract: The disposable endoscope sheath includes a low-profile sleeve member that cooperates with the endoscope shaft to establish a relatively narrow irrigation space between the sleeve member and the endoscope shaft. The sleeve member is intentionally shorter than the endoscope shaft to accommodate a variety of different endoscope lengths that are longer than the sleeve. In various embodiments of the invention the sleeve member can be positioned to establish a predetermined distal gap between the terminal end of the sleeve member and the viewing end of the endoscope shaft, to establish a flush alignment between the respective ends, or to have the endoscope shaft project slightly beyond the terminal end of the sleeve member. Irrigation fluid can thus flow across the viewing end of the endoscope flushing away surgical debris from the viewing end. The sleeve member can be a rigid or flexible structure. The size of the irrigation space is sized to permit retention of irrigation solution in the irrigation space when irrigation fluid is no longer being directed into the irrigation space.

    Abstract: Apparatus and methods for assessing tissue characteristics such as the dimensions and volume of an osteolytic lesion are disclosed. The apparatus may utilize ultrasound to provide visual and volumetric feedback related to a lesion or other tissue. Further the apparatus may be utilized to determine whether the lesion has been completely removed and filled with the appropriate amount of graft material.
