Patent number: 11596791Abstract: A peripheral nerve stimulator can be used to stimulate a peripheral nerve to treat essential tremor, Parkinsonian tremor, and other forms of tremor. The stimulator can have electrodes that are placed circumferentially around the patient's wrist or arm. Specific nerves in the wrist or arm can be targeted by appropriate spacing of the electrodes. Positioning the electrodes on generally opposing sides of the target nerve can result in improved stimulation of the nerve. The stimulation pattern may alternate between the nerves. Improved stimulation algorithms can incorporate tremor feedback, external data, predictive adaptation, and long-term monitoring data.Type: GrantFiled: February 1, 2021Date of Patent: March 7, 2023Assignee: Cala Health, Inc.Inventors: Serena HanYing Wong, Kathryn H.

Patent number: 11331480Abstract: In some embodiments, systems and methods can include a wearable device with an electrically conductive skin interface that excites the underlying nerves from a transcutaneous surface stimulator. The device may be sized for a range of user sizes with stimulation electrodes positioned to target the appropriate nerves, such as the saphenous and/or tibial nerves. The stimulation could include burst stimulation, and involve receiving an input relating to autonomic nervous system activity of the patient, and modifying at least one brain or spinal cord autonomic feedback loop relating to bladder function based on the input to balance parasympathetic and sympathetic nervous system activity of the patient.Type: GrantFiled: April 2, 2018Date of Patent: May 17, 2022Assignee: Cala Health, Inc.Inventors: Samuel Richard Hamner, Serena HanYing Wong, Kathryn H.

Patent number: 10814130Abstract: Disclosed herein are systems, devices, and methods for peripheral nerve stimulation, particularly for treating tremor. The nerve stimulation may be accomplished by a wearable nerve stimulation device, such as a band configured to be worn on the wrist or other body part. The device can accomplish targeted nerve stimulation using circumferentially spaced electrodes. In some embodiments, the device may use only the same number of electrodes as the number of nerves that are to be stimulated. A biphasic charge-balanced waveform may be used to selectively stimulate a nerve near one of the activated electrodes but not to stimulate the nerve near the other activated electrode. The device may use dry electrodes for long-term, repeated use. The dry electrodes may include a conductive base layer and a polymeric, plastic or rubber skin contact layer comprising a conductive filler. The filler may be a powder, fiber, conductive coating, etc.Type: GrantFiled: January 7, 2019Date of Patent: October 27, 2020Assignee: Cala Health, Inc.Inventors: Serena HanYing Wong, Gregory T.
