Patents by Inventor Ritwik Ummalaneni

Ritwik Ummalaneni has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190110843
    Abstract: Navigation of an instrument within a luminal network can include image-based branch detection and mapping. Image-based branch detection can include identifying within an image one or more openings associated with one or more branches of a luminal network. Image-based branch mapping can include mapping the detected one or more openings to corresponding branches of the luminal network. Mapping may include comparing features of the openings to features of a set of expected openings. A position state estimate for the instrument can be determined from the mapped openings, which can facilitate navigation of the luminal network.

  • Publication number: 20180368920
    Abstract: Certain aspects relate to systems and techniques for navigation-assisted medical devices. Some aspects relate to correlating features of depth information generated based on captured images of an anatomical luminal network with virtual features of depth information generated based on virtual images of a virtual representation of the anatomical luminal network in order to automatically determine aspects of a roll of a medical device within the luminal network.

  • Patent number: 10136959
    Abstract: An object sizing system sizes an object positioned within a patient. The object sizing system identifies a presence of the object. The object sizing system navigates an elongate body of an instrument to a position proximal to the object within the patient. An imaging sensor coupled to the elongate body captures one or more sequential images of the object. The instrument may be further moved around within the patient to capture additional images at different positions/orientations relative to the object. The object sizing system also acquires robot data and/or EM data associated with the positions and orientations of the elongate body. The object sizing system analyzes the captured images based on the acquired robot data to estimate a size of the object.

  • Publication number: 20180279852
    Abstract: Certain aspects relate to systems and techniques for luminal network navigation. Some aspects relate to incorporating respiratory frequency and/or magnitude into a navigation system to implement patient safety measures. Some aspects relate to identifying, and compensating for, motion caused by patient respiration in order to provide a more accurate identification of the position of an instrument within a luminal network.

  • Publication number: 20180214011
    Abstract: A surgical robotic system automatically calibrates tubular and flexible surgical tools such as endoscopes. By compensating for unideal behavior of a surgical instrument, the surgical robotic system can accurately model motions of the surgical instrument and navigate the surgical instrument while performing a surgical procedure on a patient. During calibration, the surgical robotic system moves the surgical instrument to a target position and receives data describing an actual position and/or orientation of the surgical instrument. The surgical robotic system determines gain values based at least on the discrepancy between the target position and the actual position. The surgical instrument can include tubular components referred to as a sheath and leader. An instrument device manipulator of the surgical robotic system actuates pull wires coupled to the sheath and/or the leader, which causes the surgical instrument to articulate.
