  • Patent number: 8412334
    Abstract: A system and method for introducing one or more stimulating drugs and/or applying electrical stimulation to the brain to treat mood and/or anxiety disorders uses an implantable system control unit (SCU), specifically an implantable signal/pulse generator (IPG) or microstimulator with one or more electrodes in the case of electrical stimulation, and an implantable pump with one or more catheters in the case of drug infusion. In cases requiring both electrical and drug stimulation, one or more SCUs are used. Alternatively and preferably, when needed, an SCU provides both electrical stimulation and one or more stimulating drugs. In a preferred embodiment, the system is capable of open- and closed-loop operation. In closed-loop operation, at least one SCU includes a sensor, and the sensed condition is used to adjust stimulation parameters.

  • Patent number: 8320600
    Abstract: A communication system is provided for a patient featuring a cushion with an opening for receiving the face of the patient. The cushion includes a microphone for receiving audible signals from the patient and one or more speakers for delivering audible signals to the patient. The microphone and speaker(s) are integrated with the cushion to avoid interfering with the comfort of the patient. In one embodiment, the audible signals are delivered to and from the patient via a communication port. In another embodiment, the system includes a display device, so the patient may view parts of the patient's body on the device and then communicate with system operators through the microphone and speaker(s).

  • Patent number: 8313453
    Abstract: A burr hole sealing device for preventing brain shift during a stimulation lead implantation procedure is provided. The device includes a suction cup ring and a self-sealing membrane positioned within the aperture of the ring. The sealing device is attached adjacent to a burr hole and over a dura layer that is exposed in the bottom of the burr hole. The stimulation lead is disposed through the burr hole, through the membrane, through the dura layer and into brain tissue. The membrane is configured to allow the lead to pass therethrough while maintaining a tight seal around the diameter of the lead, thereby hindering leakage of cerebrospinal fluid out of the cranial cavity and maintaining a substantially fixed intracranial pressure. In one embodiment, the sealing device includes a syringe for adding fluid to, or removing fluid from, the cranial cavity in response to a detected change in intracranial pressure.

  • Patent number: 8301248
    Abstract: 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.

  • Publication number: 20120245652
    Abstract: 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.
