A method and system for providing electrical pulses for neuromodulating a cranial nerve of a patient utilizing an implantable stimulator. The implantable stimulator comprising a pulse generator module and a stimulus receiver module for coupling with an external stimulator. Control circuitry ensures selective operation of one pulse generator module. The external stimulator comprises a telemetry module for remotely activating (or de-activating) programs over the internet, to arrive at the optimal program for each patient. Once the optimal “dose” is titrated using the external stimulator, the implanted pulse generator can then be programmed to such parameters. The external stimulator in conjunction with the implanted stimulus receiver can override the implanted pulse generator, to provide extra dose of therapy or to conserve the implanted battery. The external stimulator is also networked to other computers. The external programmer may also comprise a global positioning system (GPS) module for determining patient location.

The invention provides methods for inducing or increasing the vasodilation of a vessel. The invention further provides methods for inducing or increasing the flow of fluid through a vessel. An electrical impulse is applied to the vessel in order to induce or increase vessel vasodilation or to induce or increase the flow of fluid through the vessel. In a particular embodiment, a novel double-balloon catheter system incorporating electroporation technology has been designed and is used to apply the electrical impulse endoluminally.

A method and system to provide pre-determined electrical pulses for neuromodulating vagus nerve(s) or its branches to provide therapy for bulimia / eating disorders, comprises implantable and external components. The electrical pulses to vagus nerve(s) may be stimulating and / or blocking. The pulsed electrical stimulation / blocking to vagus nerve(s) may be provided using one of the following stimulation systems, such as: a) an implanted stimulus-receiver with an external stimulator; b) an implanted stimulus-receiver comprising a high value capacitor for storing charge, used in conjunction with an external stimulator; c) a programmer-less implantable pulse generator (IPG) which is operable with a magnet; d) a microstimulator; e) a programmable implantable pulse generator; f) a combination implantable device comprising both a stimulus-receiver and a programmable implantable pulse generator (IPG); and g) an implantable pulse generator (IPG) comprising a rechargeable battery. In one embodiment, the external components such as the programmer or external stimulator may comprise a telemetry circuit for networking. The telemetry circuit therefore allows for interrogation or programming of implanted device, from a remote location over a wide area network.

A defibrillator having a pair of electrodes for delivering an impedance-compensated defibrillation shock and a method thereof is provided. The defibrillator can be deployed rapidly and effectively with no or minimal clothing and hair removal. To achieve this, one electrode is coupled to a neck region of the patient, whereas the other electrode is coupled to the patient's body. Both attachment areas are easily accessible to the rescuer, thus allowing a minimally trained user to easily deploy the defibrillator to treat the patient. A wide range of energy levels that are safe for the patient can be generated selectively based on the patient impedance. The presence of voids in the electrodes decrease the effective shock impedance of the electrodes, thus allowing the defibrillator to operate at a lower level of energy when delivering the electrical pulse to the victim's heart.

A device and method for defrosting a defibrillation electrode are provided. This includes an automated external defibrillator that is capable of defrosting one or more frozen electrodes. The device is includes a portable housing containing a battery powered energy source and a controller as well as at least a pair of electrodes which are operably coupled to the housing. The electrodes are designed for attachment to the chest of a patient in need of resuscitation and contain a conductive interface medium that has temperature dependent properties. A controller is configured to selectively heat the conductive interface medium by applying limited electrical impulses and raise the electrode temperature to a desired temperature range.

A leadless cardiac pacemaker comprises a housing, a plurality of electrodes coupled to an outer surface of the housing, and a pulse delivery system hermetically contained within the housing and electrically coupled to the electrode plurality, the pulse delivery system configured for sourcing energy internal to the housing, generating and delivering electrical pulses to the electrode plurality. The pacemaker further comprises an anti-unscrewing feature disposed on either a fixation device of the pacemaker or on the housing itself. The anti-unscrewing feature can be configured to prevent the fixation device from disengaging the wall of the heart.

A system and method for providing pulsed electrical stimulation to one or both vagus nerve(s) of a patient to provide therapy for obesity, eating disorders, neurological and neuropsychiatric disorders. The electrical pulses can be provided either unilaterally or bilaterally (left and right vagus nerves) and can be supra-diaphramatic or be sub-diaphramatic. The system comprising implantable stimulator, lead(s), an external stimulator, and a programmer. The implantable stimulator, comprising a pulse generator module, and a stimulus-receiver module which is used in conjunction with an external stimulator. Control circuitry ensures selective operation of one of the modules of the implanted stimulator, at a time. Further, the external stimulator comprises a telemetry module for remotely activating (or de-activating) programs over the internet, to arrive at the optimal program for each patient. Once the optimal “dose” is titrated using the external stimulator, the implanted pulse generator can then be programmed to similar parameters. The external stimulator in conjunction with the implanted stimulus-receiver can override the implanted pulse generator module, to provide extra dose of therapy, and also to conserve the implanted battery. The external stimulator is networked to other computers. Using the networking, a physician situated remotely can monitor and program the devices, as well as, automatically generate invoicing. In one embodiment, the external stimulator also comprises GPS circuitry for locating patient.
