    摘要： Methods and devices are described for calibrating the pressure sensors of a tissue examination device to enable the sensors to produce signals that accurately indicate whether an underlying tissue structure is present in tissue being examined. In general, the calibration is performed using a substance configured to apply a selected amount of pressure to the sensors when engaged in a selected way by the tissue examination device. The sensors are calibrated based on levels of the signals produced in response to the selected amount of pressure imposed by the substance. The tissue examination device may be pressed against the substance, or the substance may be pressed against the sensors. Preferably, the substance applies the selected amount of pressure substantially uniformly to the sensors. A wide variety of substances can be used, such as a foam pad, a rubber pad, a gel, a fluid-containing balloon, and pressurized air. The calibration methods and devices are simple to perform--and in fact are preferably performed during device power up so as to be transparent to the user--while accurately compensating for variations in the signals produced by the sensors as a group, as well as for individual (i.e., sensor to sensor) variations.

    摘要： An elongated, rigid implement having a sharp distal end is insertable into a solid mass within the body of a living being through a puncture site in the solid mass created by the sharp distal end. An elongated sleeve, which engages the elongated, rigid implement, is insertable into the solid mass through the puncture site in the solid mass. Fluid is provided to an expandable chamber located in the vicinity of a distal end of the elongated sleeve through at least one channel located within the elongated sleeve, to inflate the chamber while the chamber is positioned interstitially within the solid mass. A heating device located within the expandable chamber is powered, through at least one elongated conductor located within the elongated sleeve, to heat fluid within the chamber while the chamber is filled with the fluid and is positioned interstitially within the solid mass. The inflation of the chamber while the chamber is positioned interstitially within the solid mass causes compressive ischemia of tissue surrounding the chamber, and the compressive ischemia of the tissue surrounding the chamber reduces a heat sink effect of the tissue during powering of the heating device.

    摘要： The invention features an assembly for taking a biopsy sample from a site within the body of a patient. The assembly includes a resecting device having a cutter near its distal end for resecting and containing a tissue sample and a sheath exterior to the resecting device and sized to be present within the body with the resecting device. The sheath includes an electrode element electrically isolated from the resecting device and disposed on the sheath's outer surface for cauterizing tissue. The electrode element may reside on the outer sheath, the distal end or both the outer sheath and the distal end of the assembly. The resecting device and the sheath cooperate to permit sequential resecting of a tissue sample from a resecting site and cauterizing of the site with the cutter sufficiently spaced from the electrode element to avoid heat damage to the tissue sample.

    摘要： A mechanism for configuring handheld devices is disclosed. The mechanism includes a website engine, a database, a build-to-order configuration engine, and a loader. Among other things, the built-to-order engine communicates with developers, coordinates software licenses, arranges software downloads and prevents conflicts. The loader provides actual downloads for loading the handheld device based on user input received through the website engine which conveys the user input to the database and built-to-order configuration engines. These software modules can be on the same computer, or can be divided among several computers.

    摘要： The invention features a bipolar electro-surgical apparatus having a first electrode that has a relatively large surface area for creating a diffuse current sufficient to heat a region of tissue to coagulation temperatures and a second electrode that has a relatively small surface area for creating a concentrated current region sufficient to heat tissue adjacent to the second electrode to resection temperatures. The first and second electrodes are relatively positioned along a treatment path, such that tissue is coagulated and resected as the electro-surgical apparatus is disposed along the path. The invention also features a method for bipolar electro-surgical tissue removal including positioning a pair of bipolar electrodes along a treatment path, flushing the treatment path with an ionic fluid, and imposing a voltage differential to cause current to flow through tissue between the electrodes, where the current flowing through the tissue is sufficient to heat and cause coagulation of the tissue. The invention also features a method for bipolar electro-surgical tissue removal including attaching a power connector adaptor to a resectoscope that is configured for use with a monopolar electro-surgical device and inserting a bipolar electro-surgical device having bipolar electrodes into a working channel of the resectoscope, where the bipolar electro-surgical device is sized to fit within the working channel. The method further including electrically coupling the bipolar electrodes to the power connector adaptor.
