Patent number: 11969258Abstract: A surgical system includes at least one light emitter generating light at a first intensity and an array of light sensors including a least one row of light sensors, individual light sensors in the row of light sensors adapted to generate a signal including a non-pulsatile component. The system also includes a controller coupled to the array of light sensors, the controller including an analyzer to determine the magnitudes of the non-pulsatile components at the individual light sensors in the row of light sensors, to determine if the non-pulsatile component transitions from a higher magnitude to a lower magnitude and from a lower magnitude to a higher magnitude, and if so, to determine if the first intensity should be changed to a second intensity.Type: GrantFiled: July 17, 2020Date of Patent: April 30, 2024Assignee: Briteseed, LLCInventors: Amal Chaturvedi, Hariharan Subramanian, Jonathan Gunn, Mayank Vijayvergia, Shetha Shukair, Paul Le Rolland

Patent number: 11723600Abstract: A surgical system used to determine if a vessel is within a region proximate to a working end of a surgical instrument includes at least one light emitter configured to emit light of two different wavelengths. The system also includes at least one light sensor disposed opposite the at least one light emitter, the at least one light sensor configured to detect light at the two different wavelengths and to provide a signal having a pulsatile and a non-pulsatile component for each wavelength. The system further includes a controller coupled to the at least one light sensor and configured to determine and indicate if the vessel is a ureter within the region proximate to the working end of the surgical instrument based on a ratio and a symmetry of a dip in the non-pulsatile component.Type: GrantFiled: September 5, 2018Date of Patent: August 15, 2023Assignee: Briteseed, LLCInventors: Shetha Shukair, Amal Chaturvedi, Hariharan Subramanian
