    摘要： A percutaneous insertion system is provided comprising a stylet and a lead having a distal end portion and a proximal end portion. The lead comprises a plurality of terminals positioned at the proximal end portion and a paddle-shaped body positioned at the distal end portion. The body includes two principal opposing substantially planar surfaces and a plurality of electrodes which are carried on one of the two principal surfaces of the body. The lead further comprises a plurality of conductors. A conductor of the plurality of conductors electrically couples one terminal of the plurality of terminals with at least one electrode of the plurality of electrodes. The system further comprises a channel means extending from a proximal end of the lead to a position within the body of the lead. The channel means is adapted for receiving the stylet and the body is adapted for forward driving by the stylet through the channel means. The body is further adapted for flexibility in a plane parallel to the two principal opposing planar surfaces to enhance directional steerability of the lead by the stylet through the channel means. The system further comprises a percutaneous introduction means through which the lead is passed for insertion into a human body, where a greatest transverse dimension of the paddle-shaped body is less than a corresponding interior dimension of the percutaneous introduction means.

    摘要： To avoid charge accumulation on capacitive connections to implanted electrodes during delivery of stimulation pulses, stimulation pulses are followed by active discharge pulses having opposite polarity of the stimulation pulses. The active discharge pulses preferably have at least one pulse attribute magnitude (e.g., duration, voltage, and/or current) different than a corresponding stimulation pulse and are preferably programmable. Approximately the same total net current flow is delivered during active discharge pulses as during the stimulation pulses, but in the opposite direction and optionally at a lower amplitude. In addition, by reducing the driving voltage and a variable load within the electrical path for delivery of the pulses, power dissipation during active discharge is preferably reduced.

    摘要： An implantable lead, and method of manufacturing same, and a system and method for stimulation. The lead (104, 204) has proximal and distal ends (122, 230) having, respectively, a connector portion (114, 218) with a terminal (116, 220, 222) and an electrode (126, 240, 242). An optically switched device (124, 232, 234, 236, 238) is electrically connected to the electrode and to the terminal. An optical fiber (120, 228) is optically coupled to the connector portion (114, 218) at one end and to the optically switched device (124, 232, 234, 236, 238) at another end. The optically switched device (124, 232, 234, 236, 238) conducts a stimulus from the terminal (116, 220, 222) to the electrode (126, 240, 242) in response to an optical signal transmitted over the optical fiber (120, 228).

    摘要： In one embodiment, an introducer is provided for implanting an electrical stimulation lead to enable electrical stimulation of nerve tissue. The introducer includes an outer sheath and an inner penetrator. The outer sheath is configured to accommodate insertion of the electrical stimulation lead through the outer sheath and may be inserted into a human body near the nerve tissue. The inner penetrator is removably housed within the outer sheath and includes an inner channel configured to accommodate a guide wire. The inner penetrator may be advanced along the guide wire to a desired location relative to the nerve tissue and removed from the outer sheath leaving the outer sheath substantially in position for insertion of the electrical stimulation lead through the outer sheath into position proximate the nerve tissue.
