  • Resonant structure for spatial and spectral-spatial imaging of free radical spin probes using radiofrequency time domain electron paramagnetic resonance spectroscopy
    Patent number: 6573720
    Abstract: A radiofrequency (RF) coil design, suitable for detecting time domain electron paramagnetic resonance (EPR) responses from spin probes after pulsed excitation using radiofrequency irradiation (60-400 MHz), is configured in an array of numerous surface coils of appropriate diameters connected in a parallel or axial configuration with appropriate spacing between individual surface coils to form a volume type resonator.

  • Flexible holder for a cystoscope or the like
    Patent number: 4867404
    Abstract: A flexible holder and clamping assembly for adjustably holding cystoscopes or other endoscopic instruments and retractors or the like adjacent to or on an examination tables or the like is equipped with a unique clamping assembly which permits the holding of various sized instrument shafts. The clamping assembly is equipped with a vertically adjustable spring-biased C-shaped, open-sided region which is urged into a normally open position. The instrument shaft is, after positioning relative to the patient, slid sideways into the C-shaped jaw and retained between the jaw and a pair of circumferentially opposing notches of a tubular housing. The clamp also includes a head portion having various openings and a cavity for receiving the parts and connections of the clamping assembly.
