    摘要: The implantable, electrically operated tissue stimulator system comprises a master controller module having a micro-controller, a telemetry circuit, a power module, non-volatile memory, a real time clock and a bi-directional bus, and a plurality of Input/Output modules (I/O modules) which are connected to said bi-directional bus. Each I/O module 16 comprises (1) a control logic, (2) a programmable DC/DC Converter, (3) a capacitor multiplexer, (4) two or more electrodes (channels), (5) one amplitude holding capacitor per electrode, including circuitry for isolating the holding capacitor from other holding capacitors, and a switching network used for isolating the main power source from the electrodes during delivery of the stimulation pulses. Each I/O module can be used to (I) deliver stimulus pulses to two or more preselected channels, each channel being capable of being programmed to deliver pulses having a different amplitude, pulse width and rate, and each channel being capable of being programmed to stimulate either, in isolation from other channels or in combination with other channels, (II) learn and record into non-volatile memory the morphology of a biological signal, compare the prerecorded morphology against that of freshly acquired signals, and, upon a positive comparison, respond by either, initiating or terminating a preselected stimulation schedule, modifying the on-going stimulation schedule, or up-linking a command to another external medical device to initiate delivery of medical therapy, (III) write into non-volatile memory the time and date when adjustments are made to any of the stimulation parameters along with the new stimulation value (adjustments data base), and (IV) on a periodic basis or upon command, measure and write into non-volatile memory electrode impedance values along with the time and date when the adjustments are made (impedance data base).

    摘要: The intravascular catheter has two segments; a proximal segment with high stiffness and a distal segment with lower stiffness. The catheter can also have an intermediate segment of lower stiffness than the proximal segment and higher stiffness than the distal segment. The catheter comprises a polymeric inner tube, a reinforcing inner jacket which is spirally wound over the inner tube and which becomes progressively softer from a proximal end to a distal end, and a polymeric outer sheath extruded over the inner jacket according to the teachings of U.S. Pat. No. 5,445,624. The reinforcing jacket comprises helical coiled wires or fibers of various materials and layers wound over the inner tube in order to provide improved multi-axial mechanical properties, such as torque, compression, tension and anti-kinking characteristics. Stainless steel, carbon, glass, platinum, platinum/tungsten or palladium wire in either oval, round or flat geometry are used together with single or dual layers to achieve a graduated stiffness with the reinforcing jacket being stiffer at a proximal end and softer at a distal end. Methods for making the catheter and for annealing ends of the wound wire are also disclosed.
