  • Patent number: 11131536
    Abstract: This disclosure relates to localization and tracking of an object. As one example, measurement data can be stored in memory to represent measured electrical signals at each of a plurality of known measurement locations in a given coordinate system in response to an applied signal at an unknown location in the given coordinate system. A dipole model cost function has parameters representing a dipole location and moment corresponding to the applied signal. A boundary condition can be imposed on the dipole model cost function. The unknown location in the given coordinate system, corresponding to the dipole location, can then be determined based on the stored measurement data and the dipole model cost function with the boundary condition imposed thereon.

  • Publication number: 20190269368
    Abstract: A system for ablating tissue includes an ablation catheter for insertion into the body of a patient and a robotic controller for moving the catheter within the body. The robotic controller advances the catheter until the catheter contacts the tissue surface, maintains contact between the catheter and the tissue surface, and moves the catheter along a predetermined path to create a substantially continuous lesion of ablated tissue. A display device may be used to present a graphical representation of an area of tissue to be ablated. A user interface permits selection of a plurality of treatment points on the graphical representation. The interface is preferably coupled to the controller and catheter such that the controller may cause the catheter to automatically ablate tissue at and between the plurality of treatment points in response to the received user input.

  • Patent number: 8206383
    Abstract: A system that interfaces with a workstation endocardial mapping system allows for the rapid and successful ablation of cardiac tissue. The system allows a physician to see a representation of the physical location of a catheter in a representation of an anatomic model of the patient's heart. The workstation is the primary interface with the physician. A servo catheter having pull wires and pull rings for guidance and a servo catheter control system are interfaced with the workstation. Servo catheter control software may run on the workstation. The servo catheter is coupled to an RF generator. The physician locates a site for ablation therapy and confirms the location of the catheter. Once the catheter is located at the desired ablation site, the physician activates the RF generator to deliver the therapy.

  • Patent number: 8084078
    Abstract: A multi-spectral imaging process, comprising: selecting colors for presentation in a target visualization regime; determining correspondence of said colors in the target visualization regime to colors in a source visualization regime; and fabricating a product in the source visualization regime having a coloration that produces a predetermined visual presentation of the object in the target visualization regime. Such process can be utilized to fabricate articles having coloration including a blaze orange coloration in a source visualization regime involving a human observer and a camouflage pattern in a target visualization regime involving an animal observer.
