    摘要： A cardiac defibrillation system and method includes an epicardial electrode for making electrical contact with the epicardium from a position within the pericardial space, an endocardial electrode for making electrical contact with the endocardium of the heart, and means for making electrical contact with the epicardial and endocardial electrodes. The endocardial electrode is inserted transvenously into the heart in conventional manner. The epicardial electrode is also inserted transvenously into the heart, through the heart wall, and into the pericardial space. No open chest surgery is required.

    摘要： Tissue stimulation systems generally include a pulse generating device for generating electrical stimulation pulses, at least one implanted electrode for delivering the electrical stimulation pulses generated by the pulse generating device, and a programmer capable of communicating with the pulse generating device. Stimulation pulses may be defined by several parameters, such as pulse width and amplitude. In methods of stimulating the tissue with the stimulation system, a user may adjust one of the parameters such as pulse width. The programmer may automatically adjust the pulse amplitude in response to the change in pulse width in order to maintain a substantially constant effect of the stimulation pulses.

    摘要： A neural stimulation system automatically corrects or adjusts the stimulus magnitude (stimulation energy) in order to maintain a comfortable and effective stimulation therapy. Because the changes in impedance associated with the electrode-tissue interface can indicate obstruction of current flow and positional lead displacement, lead impedance can indicate the quantity of electrical stimulation energy that should be delivered to the target neural tissue to provide corrective adjustment. Hence, a change in impedance or morphology of an impedance curve may be used in a feedback loop to indicate that the stimulation energy needs to be adjusted and the system can effectively auto correct the magnitude of stimulation energy to maintain a desired therapeutic effect.

    摘要： An implantable lead having at least one electrode contact at or near its distal end prevents undesirable movement of the electrode contact from its initial implant location. One embodiment relates to a spinal cord stimulation (SCS) lead. A first injectable material is injected into the dura space to mechanically position the electrode array with respect to the spinal cord. Conjunctively for use with adhesives, or alternatively for use instead of the adhesives, a balloon may be positioned on the electrode lead array. The balloon is filled with air, liquid or a compliant material. When inflated, the balloon stabilizes the lead with respect to the spinal cord and holds the lead in place. An elastic aspect of the balloon serves as an internal contained relief valve to limit the pressure the balloon may place on the surrounding tissues when the epidural space is constrained.

    摘要： A patient's ejection fraction is maximized through simultaneous sensing and stimulating across multiple electrodes. In one exemplary embodiment, a catheter or lead having multiple electrodes connected to a pulse generator is used. The pulse generator provides individual current control of the stimulus applied to each electrode, and further includes the ability to sense intrinsic and evoked depolarization through multiple electrodes. In another exemplary embodiment, a multiplicity of individual implantable microstimulators, each having its own current source and/or sensor and electrodes, cooperate in concert to provide multi-site stimulation and sensing.
