Publication number: 20210393160Abstract: An image display system is provided comprised of a virtual window system that creates a visual coherency between the patient's anatomical images and the actual patient by aligning the image on the display to the patient and then presenting the image to the user in a way that feels as if the user is looking directly into the patient through the display. The image shown within the image display system is dependent upon the position of the image display apparatus and the position of the user so that the display orientation of the image may be biased slightly toward the user to improve ergonomics and usability.Type: ApplicationFiled: May 28, 2021Publication date: December 23, 2021Inventors: Daniel WALLACE, Gregory STAHLER, Aaron GROGAN

Publication number: 20120116253Abstract: A robotic catheter manipulator includes a guide catheter including proximal and distal ends and lumen extending there through. A flexible bellows is secured at one end to the proximal end of the guide catheter and at the other end to a seal configured to receive a working catheter. In a loaded state, the working catheter is fixed relative to the seal. A ditherer is operatively connected to the seal for dithering the working catheter relative to the guide catheter when placed therein. The robotic catheter manipulator includes at least one force sensor for measuring the force applied to the working catheter by the ditherer. Force measurements may be translated into an estimated force that is experienced at the distal end of the working catheter which may then be displayed to the physician via a monitor or display.Type: ApplicationFiled: January 9, 2012Publication date: May 10, 2012Applicant: HANSEN MEDICAL, INC.Inventors: Daniel T.

Publication number: 20120022405Abstract: A method for estimating the force on a distal end of a working catheter includes positioning a portion of a robotically controlled guide catheter and working catheter into a body lumen wherein a distal end of the working catheter projects distally from a distal end of the guide catheter. The working catheter and guide catheter are dithered with respect to one another using a dithering device operatively connected to a proximal portion of the working catheter. The coupling may occur directly to the working catheter or via a seal such as a Touhy seal. The force experienced by the working catheter at a proximal region is measured through at least one dithering cycle. The force at the distal end of the working catheter is then estimated based on the measured force at the proximal region. The estimated force may be displayed to a physician on, for example, a monitor.Type: ApplicationFiled: October 3, 2011Publication date: January 26, 2012Applicant: HANSEN MEDICAL, INC.Inventors: Daniel T.
