Patent number: 11839360Abstract: The present disclosure relates generally to fluorescent imaging devices, systems, and methods for an endoscopic procedure, and in particular, indocyanine green (ICG) fluorescence. In some embodiments, a device for fluorescent imaging during an endoscopic procedure may include an attachment connectable to a distal end of an endoscope. The attachment may include a first filter alignable with a light source of the endoscope, and a second filter alignable with an imaging device of the endoscope. The first filter may be positionable such that in a first position the first filter is aligned with the light source, and in a second position the first filter is out of alignment with the light source. The second filter may be positionable such that in a first position the second filter is aligned with the imaging device, and in a second position the second filter is out of alignment with the imaging device.Type: GrantFiled: January 4, 2019Date of Patent: December 12, 2023Assignees: Boston Scientific Scimed, Inc., The Johns Hopkins UniversityInventors: Sritam P. Rout, Marc Chelala, Maria F. Torres, Kyle R. Cowdrick, Amir Hossein Soltanianzadeh, David M. Gullotti, Pankaj J. Pasricha, Nicholas J. Durr, Ryan V. Wales

Patent number: 11229418Abstract: An aspect of the present disclosure is to provide a device or needle placement system including a needle having a proximal end and a distal end, and an ultrasound transducer element attached to the distal end of the needle. The system also includes a needle constraining assembly configured to receive and constrain the needle to only rotational degrees of freedom within a range of angular motion. The system further includes a needle sensor system incorporated into the constraining assembly to sense an angular orientation of the needle with the range of angular motion. The system also includes an ultrasound data processor configured to communicate with the transducer element to receive ultrasound detection signals and communicate with the needle sensor system to receive needle angular orientation signals. Based on the ultrasound detection and the needle angular orientation signals, the ultrasound data processor can calculate synthetic aperture ultrasound images.Type: GrantFiled: May 2, 2017Date of Patent: January 25, 2022Assignee: The Johns Hopkins UniversityInventors: Nisu Patel, Ernest Scalabrin, Karun Kannan, Kush Gupta, Larissa Chan, Mateo Paredes, Melissa Lin, Shayan Roychoudhury, Suraj Shah, Abhay Moghekar, Emad M.

Publication number: 20220019861Abstract: A device may receive a coherent energy illuminated image, of a particular object, that includes laser speckle. The device may process, using a laser speckle reduction model, the coherent energy illuminated image to generate a laser speckle-reduced image. The device may provide the laser speckle-reduced image as output to permit diagnostics based on the laser speckle-reduced image.Type: ApplicationFiled: October 22, 2019Publication date: January 20, 2022Applicant: The Johns Hopkins UniversityInventors: Nicholas J. DURR, Taylor L. BOBROW, Faisal MAHMOOD
