摘要： An instrument (10) for use in surgery is provided. The instrument has a heating element (12) with a working surface for providing hemostasis at an auto-regulated temperature. The heating element (12) may be disposed on a flexible elongated shaft (18) for use in endoscopic surgery, or a shorter shaft (18A) for use in open surgical procedures. The working surface may include a tapered edge (11) for providing thermally-enhanced cutting and a non-stick coating for operating the instrument at low auto-regulation temperatures. A process for making such instruments and methods of employing such devices in performing surgery are also described.

摘要： An adaptor cable (20) and methods are provided for use with electrosurgical bipolar instruments (12), and standard commercially available electrosurgical generators (10) that reduce arcing. The adaptor cable (10) limits the peak to peak voltage developed between the electrodes of the electrosurgical instrument (12) by providing a minimum load impedance between the output terminals (14) of the electrosurgical generator (10).

摘要： Dual program audio apparatus is provided having two or more sources of input audio program signals (34, 35, 36, 37, 38), switching circuitry (41) for selecting two of the input audio signals for amplification, one or more amplifiers (42, 43) for amplifying the selected input audio program signals, and one or more audio speakers (39, 40) for enabling a listener to hear both audio programs simultaneously. Volume control circuitry (44, 45) is provided for selecting a higher volume level for a foreground program and a relatively lower volume for a background program and circuitry is provided for selectively interchanging the foreground and background programs either instantaneously or gradually and continuously.

摘要： A hemostatic surgical blade (10) and methods of manufacturing such blades are provided, wherein the blade comprises a laminate region (40) having a hardenable center layer (22) and highly thermally conductive outer layers, joined to a second region of a low thermal conductivity material (21). A heating element (16) is secured to the laminate region and in thermal communication therewith to thermally reform the collagen of tissue as it is incised. The heat generated by the heating element (16) is conducted to the cutting edge (13) of the blade to maintain the cutting edge temperature within 20 °C to 70 °C of a user-selected operating temperature. The second region (21) reduces the conduction of heat to the handle of the instrument. The heating element (16) comprises a thermally conductive dielectric layer attached to an outer surface of the laminate region (17), resistive conductive elements deposited on the dielectric (18), a second dielectric layer (19) covering the resistive conductor elements, and an adherent coating (12) disposed thereon to reduce coagulum buildup on the blade.
