Abstract:
A system and method for providing a volume of activation (VOA) of a stimulation electrode leadwire may include a processor that calculates a VOA for each of a plurality of sets of parameter settings of the leadwire, stores in a database each of the calculated VOAs in association with the respective set of parameter settings for which it was calculated, performs a curve fitting on threshold values determined for a plurality of waveforms to obtain an equation, obtains a set of parameter settings of the leadwire for a stimulation, and determines a VOA for the obtained set of parameter settings based on the stored VOAs, for example, using the equation.
Abstract:
A burr hole assembly for use in neurosurgery. In one aspect, the burr hole assembly comprises a burr hole portion and one or more sensors, such as EEG sensors, temperature sensors, intracranial pressure sensors, or motion sensors. In certain embodiments, an input/output unit, which may include a multiplexer, provides a coupling between the sensors and a brain stimulation system which operates in cooperation with the burr hole assembly. In another aspect, the burr hole assembly comprises a burr hole portion and a rotation mechanism which operates in cooperation with an electrode lead. In certain embodiments, the burr hole assembly includes a control system for controlling the rotation mechanism. Also disclosed are systems comprising a burr hole assembly and various components of a brain stimulation system, such as pulse generators, electrode leads, lead extension, or external control systems.
Abstract:
The invention may provide an antenna device including a communication interface to couple the antenna device to an external device and a package housing with an adhesive surface. A planar antenna pattern may be fabricated on a substrate within the package housing, wherein the antenna pattern is configured to transmit an ultra-wideband signal and to receive a reflection of the transmitted signal.
Abstract:
Methods of neuromodulation in a live mammalian subject, such as a human patient The method comprises applying an electrical signal to a target site in the nervous system, such as the brain, where the electrical signal comprises a series of pulses. The pulses includes a waveform shape that is more energy-efficient as compared to a corresponding rectangular waveform. Non-limiting examples of such energy-efficient waveforms include linear increasing, linear decreasing, exponential increasing, exponential decreasing, and Gaussian waveforms. Also described are apparatuses for neuromodulation and software for operating such apparatuses.

Abstract:
A therapy tracking system and method may include a processor that obtains physiological information regarding a patient and a time period during which a deep brain stimulation (DBS) therapy is conducted. The information may be organized into a plurality of sessions. The processor may arrange in a display device a separate representation of the information for each of at least a subset of the sessions, such that the sessions are presented in order of time.
Abstract:
Electrode devices having directional electrodes for use in deep brain stimulation or other uses. In one aspect, an electrode assembly comprises an elongate lead and a lead guide that are engageable with each other in a coaxial relationship. When the elongate lead and the lead guide are engaged with each other, the two components are rotationally fixed in relation to each other, hi another aspect, an elongate lead comprises a radiologically-visible feature for indicating the orientation of the elongate lead. In yet another aspect, an electrode system is capable of determining the position and/or orientation of an electrode positioned within a body. In other aspects, methods for electrically stimulating a target site in the body are disclosed.
Abstract:
A fluid delivery system (26) for an automated processor (A) delivers washing, microbial decontaminant, and rinse fluids to spray nozzles (102, 104, 106, 108, 110) in a chamber (12) for sequentially spraying the fluids over a lumened device (B), such as a n endoscope. The fluid delivery system also delivers the fluids to connection ports (150, 152, 154) which connect with internal passages (187) of the device for delivering the fluids thereto. Leaking connectors (184) connect the automated processor connection ports with inlet ports (196) of the device and allow a portion of the washing, decontaminant, and rinsing solutions to leak from each inlet port. The endoscope is supported on a rack which is agitated by an activation system (330). A computer control system (80) controls cleaning, decontamination, rinsing, and drying stages of a cycle, which are all carried out within the chamber, obviating the need for human contact with the device during processing. A door locking and latching mechanism (90) ensures that the door remains locked during the washing, decontamination, and rinse cycle to avoid accidental injury to an operator from strong chemicals used in the system.
