Publication number: 20240016437Abstract: Systems and methods are disclosed for conducting spinal cord stimulation or other neurostimulation and sensing evoked compound action potential (ECAP) signals. The sensed signals may be processed to isolate ECAP features from noise and/or interfering signals. The isolated ECAP features may be used to control neurostimulation therapy for the patient, such as to quantify or measure lead migration and adjust a neurostimulation therapy for the patient to account for an impact of any detected lead migration, or other purposes (e.g., to guide an implant procedure).Type: ApplicationFiled: July 12, 2023Publication date: January 18, 2024Inventors: Mingming Zhang, Hyun-Joo Park, Erika Ross, Ameya Nanivadekar, Nishant Verma

Publication number: 20230381509Abstract: Real-time sensing of cerebrospinal fluid (CSF) clearance can be used to optimize electrode target engagement of the peripheral cranial nerves and detect associated changes within the connected nerve truck and brain. This CSF clearance data may be used in “open loop” systems to inform operator-controlled programming or sent directly to the stimulator itself to titrate programming “closed loop” on the device.Type: ApplicationFiled: May 25, 2023Publication date: November 30, 2023Inventors: Kip Ludwig, Nishant Verma, Justin Williams

Publication number: 20230381508Abstract: Administration of low frequency electrical stimulation of the cranial nerves delivered during sleep increases the presence and function of aquaporin-4 (AQP4) channels in the astrocytic endfeet surrounding descending arterioles in the brain. This underlying low frequency stimulation pattern is overlaid with temporally patterned ‘bursts’ of higher frequency stimulation to pulse the underlying artery to drive cerebrospinal fluid (CSF) penetration into the parenchyma. This also serves to create more movement in general within the parenchymal extracellular space to increase the probability of waste biomolecules to interact with sites for active transport out of the brain. During the period of sleep, these two layered patterns will be periodically replaced with multiple continuous periods of stimulation at gamma frequency to promote a more phagocytic phenotype in glial cells to help break down waste biomolecules and misfolded proteins for subsequent clearance.Type: ApplicationFiled: May 25, 2023Publication date: November 30, 2023Inventors: Kip Ludwig, Justin Williams, Kevin Cheng, Nishant Verma

Patent number: 11800968Abstract: Methods, endoscopic systems, and non-transitory, machine-readable storage media for adjusting an exposure of an endoscopic system are described. In an embodiment, the methods include emitting light with a light source into a proximal end of an endoscope light pipe; generating received light signals with a photodetector based on light received through the endoscope light pipe by the photodetector; displaying, with a display module, images based on the received light signals having a current image brightness; monitoring the received light signals for changes to the current image brightness; and adjusting a light source illuminance level, and in some embodiments a photodetector gain and exposure time, based on the current image brightness to maintain a target image brightness of the display module. In an embodiment, a brightness adjustment step size is less than a just-noticeable difference in brightness of an eye and is directly proportional to the current image brightness.Type: GrantFiled: November 28, 2022Date of Patent: October 31, 2023Assignee: Verily Life Sciences LLCInventors: Nishant Verma, Ryan L Robertson
