摘要:
A small implantable stimulator(s) with at least two electrodes is small enough to have the electrodes located adjacent to a nerve structure at least partially responsible for headache and/or facial pain. The small stimulator provides a means of stimulating a nerve structure(s) when desired, and may be implanted via a minimal surgical procedure.
摘要:
A small implantable stimulator(s) includes at least two electrodes for delivering electrical stimulation to surrounding tissue. The small stimulator provides means of stimulating a neoplasm with direct electrical current, such as relatively low-level direct current, without the need for external appliances during the stimulation session. The stimulator may be configured to be small enough to be implanted entirely within a neoplasm. Open- and closed-loop systems are disclosed.
摘要:
Systems and methods for introducing one or more stimulating drugs and/or applying electrical stimulation to the brain to alleviate pain use at least one implantable system control unit (SCU), producing electrical pulses delivered via electrodes implanted in the brain and/or producing drug infusion pulses, wherein the stimulation is delivered to targeted areas in the brain. In some embodiments, one or more sensed conditions are used to adjust stimulation parameters.
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.
摘要:
Miniature implantable stimulators (i.e., microstimulators) with programmably configurable electrodes allow, among other things, steering of the electric fields created. In addition, the microstimulators are capable of producing unidirectionally propagating action potentials (UPAPs).

A small implantable stimulator(s) includes at least two electrodes for delivering electrical stimulation to surrounding tissue. The small stimulator provides means of stimulating the prostate with direct electrical current, such as relatively low-level direct current, without the need for external appliances during the stimulation session. The stimulator may be configured to be small enough to be implanted entirely within the prostate. Open- and closed-loop systems are disclosed.
摘要:
Miniature implantable stimulators (i.e., microstimulators) are capable of producing unidirectionally propagating action potentials (UPAPs). The methods and configurations described may, for instance, arrest action potentials traveling in one direction, arrest action potentials of small diameters nerve fibers, arrest action potentials of large diameter nerve fibers. These methods and systems may limit side effects of bidirectional and/or less targeted stimulation.
摘要:
A small implantable stimulator(s) with at least two electrodes is small enough to have the electrodes located adjacent to a nerve structure at least partially responsible for epileptic seizures. The small stimulator provides a means of stimulating a nerve structure(s) when desired, and may be implanted via a minimal surgical procedure.
