    摘要: An implantable stimulator(s), small enough to be located near or within an area of the spine responsible for sensations in a region experiencing chronic pain uses a power source/storage device, such as a rechargeable battery. Periodic recharging of such a power source/storage device is accomplished, for example, by inductive coupling with an external appliance. The small stimulator provides a means of stimulating a nerve(s) or other tissue when desired, without the need for external appliances during the stimulation session. When necessary, external appliances are used for the transmission of data to and/or from the stimulator(s) and for the transmission of power, it necessary. In a preferred embodiment, the system is capable of open- and closed-loop operation. In closed-loop operation, at least one implant includes at least one sensor, and the sensed condition is used to adjust stimulation parameters.

    摘要: A small implantable stimulator(s) includes at least two electrodes for delivering electrical stimulation to surrounding tissue and/or a pump and at least one outlet for delivering a drug or drugs to surrounding tissue. One electrochemotherapy method disclosed includes delivery of electrical stimulation in the form of a direct electric current and/or a periodic waveform that locally potentiates the cytotoxic effects of a systemically and/or locally administered chemotherapy agent(s). Open- and closed-loop systems are disclosed.
