摘要： A medical electrode lead employing one or more elongated electrode coils embedded in the surface of a flexible base pad. The electrode coils take the form of space wound coils following tortuous paths over the surface of the base pad to provide a large surface area electrode. The electrode coils include a plurality of spaced, generally parallel electrode coil segments. Located intermediate adjacent the parallel electrode coil segments are grooves or pleats, molded into the base pad. These grooves or pleats provide increased elasticity of the electrode and increased ability to conform to the contours of the heart. Insulative cores taking the form of plastic tubes are located within the electrode coils to prevent tissue ingrowth between the individual electrode coils, without induly reducing flexibility of the electrode.

摘要： Disclosed herein are systems and methods for extending one or both of the discharge electrodes in a transverse discharge gas laser chamber in which one or both the electrodes are subject to a dimensional change due to erosion. Electrode extension can be performed to increase the chamber life, increase laser performance over the life of the chamber, or both. Operationally, the inter-electrode spacing may be adjusted to maintain a specific target gap distance between the electrodes or to optimize a specific parameter of the laser output beam such as bandwidth, pulse-to-pulse energy stability, beam size, etc.
