摘要:
Methods of delivering optical stimulation to a target tissue from an optical stimulation device are provided. One method comprises sensing a temperature at the optical stimulation device or proximate to the optical stimulation device, and adjusting the delivery of light to the target tissue based on the sensed temperature. Another method comprises delivering the light to the target tissue with an optical light guide and sensing bioelectric signals with a sense electrode, wherein the optical light guide and the sense electrode each comprise a material that produces substantially no induced current in an electromagnetic field. Another method comprises delivering light from a light source of an optical stimulation device to a window of the optical stimulation device, delivering the light from the window to an optical light guide optically connected to the window, and delivering the light to a target tissue via the optical light guide.
摘要:
A method of reforming a wet-tantalum capacitor is disclosed. The method comprises charging the capacitor to a voltage that is substantially less than one of a maximum and rated voltage for the capacitor. The method also comprises providing an open circuit condition and allowing the capacitor to at least partially discharge through leakage current.

摘要:
A method of reforming a wet-tantalum capacitor includes providing a medical device comprising a wet-tantalum capacitor. The capacitor has a rated voltage and including a hydrated anodic deposit. The method further includes charging the capacitor to a voltage that is less than approximately seventy-five percent of the rated voltage and at least partially discharging the capacitor after the charging step. The charging step is performed at a sufficient voltage to dehydrate the anodic deposit while not significantly decreasing the service life of the capacitor.
