Publication number: 20240165410Abstract: Arousal of a patient is enhanced and wakefulness modulated by neurostimulation. Bioelectrical activity of the nervous system of the patient is monitored and characteristics of the monitored bioelectrical activity associated with a state of reduced arousal and/or wakefulness are detected. In response to such characteristics, stimulation signals selected to arouse the patient are generated and supplied to stimulation transducers to stimulate a neural network of a patient associated with arousal.Type: ApplicationFiled: March 28, 2022Publication date: May 23, 2024Inventors: Alkistis Stavropoulou DELI, Timothy DENISON, Alexander Laurence GREEN

Publication number: 20220143415Abstract: An emulation apparatus emulates an electrophysiological signal derived from a target area of a human or animal nervous system under the influence of a stimulation signal applied to the human or animal body. A prior signal generator generates a prior signal representing an electrophysiological signal in the absence of stimulation. A test signal representing a stimulation signal is received and used by a modelling unit to derive a modulation signal representing the degree of modulation of the electrophysiological signal, in accordance with a model of the temporal evolution of the modulation of the electrophysiological signal caused by the stimulation signal. A modulation unit modulates the prior signal in accordance with the modulation signal to output an emulation signal representing an electrophysiological signal derived under the influence of the stimulation signal. The emulation apparatus has wide use in neuroscience research, bioengineering and clinical applications.Type: ApplicationFiled: February 13, 2020Publication date: May 12, 2022Inventors: Jean DEBARROS, Peter BROWN, Huiling TAN, Timothy DENISON

Publication number: 20220032065Abstract: Devices and methods provide for the sensing of physiological signals by providing a stimulation waveform that includes a stimulation pulse followed by an active recharge pulse to clear the charge in capacitors within the stimulation path. The active recharge pulse is followed by a period of passive recharge and then a period of no recharge. Non-neurological sources of artifacts within the sensed physiological signal may be handled by providing a brief period of passive recharge followed by a lengthy period of no recharge, which is made possible by the use of the active recharge pulse prior to the passive recharge. The period of no recharge removes any low impedance path to ground from the stimulation electrodes, which allows an amplifier of the sensing circuit to provide common mode rejection of non-neurological signals, such as cardiac signals, present at the sensing electrodes.Type: ApplicationFiled: October 14, 2021Publication date: February 3, 2022Inventors: Scott Stanslaski, Robert Devine, Timothy Denison, Vincent Roczniak, Todd Smith, Thomas Adamski

Patent number: 9042995Abstract: Implantable devices and related systems utilize power management features in conjunction with a recharge circuit that includes a coil and capacitance. The reactance such as the capacitance and/or inductance may be variable such that in the event of an overcharge condition, the reactance may be varied to change the resonant frequency of the circuit of the coil from the recharge frequency to another frequency to reduce the power being received. Other power management features may additionally or alternatively be employed. For instance, the device may send an uplink telemetry signal to an external device to request that recharge power be decreased. The device may switch additional resistance into the circuit of the coil to reduce the Q of the circuit. As another example, the device may clamp the circuit of the coil to ground.Type: GrantFiled: February 3, 2010Date of Patent: May 26, 2015Assignee: MEDTRONIC, INC.Inventors: David A. Dinsmoor, Joel A.
