A neurostimulation system and method of blocking a neural axon. Time-varying electrical energy is conveyed to a blocking site on the neural axon for an initial phase. The conveyed electrical energy has an amplitude and frequency during the initial phase sufficient to block action potentials from propagating along the neural axon from a location proximal to the blocking site to a location distal to the blocking site. The time-varying electrical energy is conveyed to the blocking site on the neural axon for a subsequent phase contiguous with the initial phase. The conveyed electrical energy has a decreased amplitude and a frequency during the subsequent phase sufficient to maintain blocking of the action potentials along the neural axon from the location proximal to the blocking site to the location distal to the blocking site.

Implantable medical leads and implantable lead extensions include a shield. The implantable medical lead is coupled to the implantable lead extension. Stimulation electrodes of the implantable medical lead contact stimulation connectors within a housing of the implantable extension to establish a conductive pathway for stimulation signals from filars of the implantable extension to filars of the implantable medical lead. Continuity is established between the shield of the implantable medical lead and the implantable extension by providing a radio frequency conductive pathway within the housing. The radio frequency conductive pathway extends from a shield of the implantable extension to a shield connector that contacts a shield electrode of the implantable medical lead. The radio frequency conductive pathway may have various forms such as a jumper wire or an extension of the shield within the implantable extension.

Tissue ablation with irreversible electroporation

Номер: US20120071874A1
Автор: Boris Rubinsky, Rafael Davalos
Принадлежит: UNIVERSITY OF CALIFORNIA

A new method for the ablation of undesirable tissue such as cells of a cancerous or non-cancerous tumor is disclosed. It involves the placement of electrodes into or near the vicinity of the undesirable tissue through the application of electrical pulses causing irreversible electroporation of the cells throughout the entire area of the undesirable tissue. The electric pulses irreversibly permeate the cell membranes, thereby invoking cell death. The irreversibly permeabilized cells are left in situ and are removed by the body immune system. The amount of tissue ablation achievable through the use of irreversible electroporation without inducing thermal damage is considerable.

Sample and hold circuitry for monitoring electrodes and other voltages in an implantable neurostimulator is disclosed. The sample and hold circuitry in one embodiment contains multiplexers to selected appropriate voltages and to pass them to two storage capacitors during two different measurement phases. The capacitors are in a later stage serially connected to add the two voltages stored on the capacitors, and voltages present at the top and bottom of the serial connection are then input to a differential amplifier to compute their difference. The sample and hold circuitry is particularly useful in calculating the resistance between two electrodes, and is further particularly useful when resistance is measured using a biphasic pulse. The sample and hold circuitry is flexible, and can be used to measure other voltages of interest during biphasic or monophasic pulsing.

Hearing Aid Microactuator

Номер: US20120190914A1
Автор: Armand P. Neukermans, S. George Lesinski
Принадлежит: OTOKINETICS Inc

A fenestration piercing the otic capsule bone of the cochlea receives a therapeutic appliance, such as a microactuator, plug, micropump for drug or therapeutic agent delivery, electrode, and the like. Several different ways of achieving a ‘water tight’ seal between the otic capsule bone and the therapeutic appliance are provided. The therapeutic appliance may be implanted with or without a sheath or sleeve lining the wall of the fenestration formed using specialized surgical burrs. The burrs permit safely fenestrating the otic capsule bone adjacent to the scala tympani of the cochlea without damaging the basilar membrane or organ of corti. This approach may also be adopted for safely fenestrating other areas of the inner ear such as the scala vestibuli, bony labyrinth of semicircular canals, or walls of the vestibule, or the oval or round windows thereof.

A treatment for Parkinson's Disease uses a stimulus electrode implanted in a subthalamic nucleus with a chemosensor implanted in a globus pallidus pars interna (GPi) of the subject. A level of a neurochemical is sensed with the chemosensor, and compared to a desired level. When the level of the neurochemical is less than desired, an electrical stimulation is provided to the stimulus electrode. In alternative embodiments, the neurochemical sensed is glutamate or dopamine. An alternative system uses a chemosensor implanted in the striatum instead of the GPi. An alternative system for treating benign essential tremor uses a stimulus electrode implanted in the thalamus with feedback taken from a chemosensor in the striatum.
