Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to medical devices, systems and methods to endoscopically suture or otherwise manipulate tissues, organs and/or structures within a body of a patient.

Abstract: A fingerbrush for cleaning multiple surfaces of a child's teeth and/or gum line including a body member having a front side, a rear side and a cavity extending therewithin. The front side of the body member includes a brush head having a pair of spaced side panels and a plurality of bristle members positioned and located on and between the side panels. The rear side of the body member includes vertical ribbing positioned and located between the top and base portions thereof and may further include a plurality of projections. The brush head is used to clean multiple teeth and/or gum line surfaces of a child, while the vertical ribbing and projections, used either independently or together, help to protect a user's finger from being bitten during the cleaning process and also aid in massaging a child's gums during teething.

Abstract: A gated amplifier drives a gradient coil when the gate signal is applied and the gate signal also controls an FET switch to disconnect a shim power supply from shim coils and connects the shim power supply instead to a dummy load. When the gate signal is removed, the shim coil is restored to operation from the shim power supply.

Abstract: The cross polarization condition for hetero-coupled NMR spectroscopic investigations for a sample spinning at rate .omega..sub.R is improved by causing at least one of the RF excitation channels to emit pulses in synchronous relationship to the sample spinner during the cross polarization contact whereby dependence of the NMR signal on mechanical spin rate .omega..sub.R is reduced.
