Publication number: 20230121855Abstract: A virtual or augmented reality system is disclosed which is capable of both (i) evaluating prospective implantable neurostimulator patient candidates, and (ii) determining optimal stimulation settings for already-implanted neurostimulation patients. Physiological sensors are included with the system to provide objective measurements relevant to a patient's symptoms, such as pain in a Spinal Cord Stimulation (SCS) system. Such objective measurements are determined during the presentation of various virtual or augmented environments, and can be useful to determining which patients are suitable candidates to consider for implantation. Stimulation settings for already-implanted patients may be adjusted while presenting a virtual or augmented environment to the patient, with objective measurements being determined for each stimulation setting. Such objective measurements can then be used to determine optimal stimulation settings for the patient.Type: ApplicationFiled: December 20, 2022Publication date: April 20, 2023Inventors: Elizabeth M. Annoni, Bryan A. Clark, Dennis Zottola, Kyle H. Srivastava, Jonathan B. Shute

Publication number: 20220080154Abstract: A navigation-assisting flexible elongate member, a navigation-assisting system, and a navigation-assisting method for use in navigating within a body to a treatment site. A navigation-assisting sensor, such as an optic fiber, an inductive sensor, a piezoelectric sensor, or a camera, is provided within the wall of the flexible elongate member, so as not to occupy space within a working channel defined by and through the flexible elongate member. When the distal end of the flexible elongate encounters an obstacle/another object (e.g., body tissue or a lumen wall), the navigation-assisting sensor generates a signal indicative of such encounter. Such signal is converted into information (such as by a control unit) usable to navigate the flexible elongate member away from the obstacle and on course to the treatment site.Type: ApplicationFiled: September 13, 2021Publication date: March 17, 2022Inventors: Kyle H.

Publication number: 20200372409Abstract: A system and method for compensating for electromagnetic (EM) distortion fields caused by one or more distortion objects is provided. A system and method for compensating for electromagnetic (EM) distortion fields caused by one or more distortion objects is provided. For example, an EM compensation device receives a plurality of EM field calibration measurements. The EM compensation device trains a machine learning dataset to compensate for the EM distortion fields from the one or more distortion objects using the plurality of EM field calibration measurements and/or an EM field model. The EM compensation device receives one or more EM field procedure measurements from a medical device performing a medical procedure. The EM compensation device predicts a spatial location of the medical device based on the EM field procedure measurement and the machine learning dataset.Type: ApplicationFiled: May 21, 2020Publication date: November 26, 2020Inventors: Kyle H.

Publication number: 20200279643Abstract: Embodiments of the present disclosure relate to systems and methods for determining the size of a medical device to implant in a patient using deep learning techniques. In at least one embodiment, a method comprises receiving a plurality of images, each of the plurality of images including a representation of a portion of a patient's anatomy in which the medical device is to be implanted. The method further comprises extracting a centerline of the representation of the patient's anatomy from the plurality of images and extracting planes orthogonal to the centerline. In addition, the method comprises identifying, using a segmentation model that segments the extracted planes, an implantation site. And, the method comprises determining, using a medical device size classification model that classifies the implantation site, a size of the medical device to be implanted at the implantation site.Type: ApplicationFiled: July 17, 2019Publication date: September 3, 2020Inventors: Kyle H.
