摘要:
An implantable stimulator(s), small enough to be located near or adjacent to an autonomic nerve(s) innervating urinary and/or gastrointestinal structures, 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, if 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.

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.

摘要:
A method and system for treatment of incontinence, urgency, frequency, and/or pelvic pain includes implantation of electrodes on a lead or the discharge portion of a catheter adjacent the perineal nerve(s) or tissue(s) to be stimulated. Stimulation pulses, either electrical or drug infusion pulses, are supplied by a stimulator implanted remotely, and through the lead or catheter, which is tunneled subcutaneously between the stimulator and stimulation site. For instance, the system and method reduce or eliminate the incidence of unintentional episodes of bladder emptying by stimulating nerve pathways that diminish involuntary bladder contractions, improve closure of the bladder outlet, and/or improve the long-term health of the urinary system by increasing bladder capacity and period between emptying. Moreover, the system and method allow a patient to be taught to receive one or more patterns of neural stimulation that can be prescribed by a physician and administered without continuous oversight by a clinical practitioner.
摘要:
A method and system for treatment of incontinence and/or pelvic pain includes the injection or laparoscopic implantation of one or more battery- or radio frequency-powered microstimulators (10) beneath the skin of the perineum and/or adjacent the tibial nerve. The devices are programmed using radio-frequency control via an external controller (20, 30)) that can be used by a physician to produce patterns of output stimulation pulses judged to be efficacious by appropriate clinical testing to diminish symptoms. The stimulation program is retained in the microstimulator device (10) or external controller (20) and is transmitted when commanded to start and stop by a signal from the patient or caregiver. The system and method reduce the incidence of unintentional episodes of bladder emptying by stimulating nerve pathways (8) that diminish involuntary bladder contractions, improve closure of the bladder outlet, and/or improve the long-term health of the urinary system by increasing bladder capacity and period between emptying. The incidence of fecal incontinence is similarly reduced or eliminated. Furthermore, the system and method reduce or eliminate the incidence of pelvic pain by chronically stimulating nerve pathways that derive from the sacral roots using a miniature implantable neurostimulator that can be implanted with a minimal surgical procedure. Moreover, the system and method allow a patient to be taught to receive one or more patterns of neural stimulation that can be prescribed by a physician and administered without continuous oversight by a clinical practitioner.

A method for treating a patient may include treating coronary artery disease in combination with angina pectoris and/or the control of angina pain by delivering chemical and/or electrical stimulation pulses to the cardiac and/or nervous tissue of the patient in a coordinated manner. A system for treating a patient suffering from coronary artery disease and angina may include a stimulator that generates at least one pulse in accordance with prescribed parameters, a catheter, a lead, and/or a sensor.
摘要:
An implantable stimulation device includes a device body; at least one set of partitioned electrodes disposed on a portion of the device body and configured and arranged for application of electrical stimulation to adjacent tissue; and insulating material separating the partitioned electrodes from each other. Each set of partitioned electrodes includes a plurality of partitioned electrodes disposed around a circumference of the device body. The implantable stimulation device can be configured and arranged so that each of the partitioned electrodes is independently programmable.
摘要:
A lead assembly for a small implantable medical device connects a remote electrode to a microdevice and inhibits fluid ingress into the connection. Microdevices may provide either or both tissue stimulation and sensing. Known microdevices include spaced apart electrodes on the outer surface of the microdevice. The lead assembly includes an insulated lead including a proximal end and a distal end, with at least one conductor therebetween; at least one electrode at the distal end of the lead and electrically connected to the at least one conductor, and a connector attached to the proximal end of the lead and adapted to be removably connectable to the microdevice. The connector includes at least one contact to electrically connect at least one device electrode on the microdevice to the at least one conductor. The lead assembly is configured to inhibit fluid ingress into the connector.
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.

An implantable stimulator(s) with at least two electrodes, which is small enough to have the electrodes located adjacent to a cavernous nerve(s) or other nerve(s) innervating the reproductive organs, uses a power source/storage device, such as a rechargeable battery. Periodic recharging of such a battery is accomplished, for example, by inductive coupling with an external appliance. The small stimulator provides means of stimulating a nerve(s) 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. In a preferred embodiment, the system is capable of open-and closed-loop operation. In closed-loop operation, at least one implant includes a sensor, and the sensed condition is used to adjust stimulation parameters.
