摘要:
An anti-free-flow mechanism includes an occluder mechanism which is disposed along a segment of tubing and a mounting structure. The occluder mechanism is normally in a biased closed position, but may be moved into an open position by placement in the mounting structure. However, unless force is applied to keep the occluder mechanism in the mounting structure, the occluder will move relative to the mounting structure and return to the first, closed position.
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:
A system is described having a heating device with a focused antenna array, a chair, a cabinet, at least one temperature monitoring device, a cooling system, and a controller. The system may be used to heat and monitor internal tissue and/or fluid in an individual in a non-invasive way.
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.
