  • Patent number: 8409234
    Abstract: Robotic instrument systems, apparatus, and methods for controllably rotating a tool or adapter coupled to a distal portion of a medical instrument such as a catheter. An interface, which may be integral with the medical instrument or a component of a separate rotatable apparatus or adapter, is operably coupled, e.g. fixedly coupled, to the distal end of the instrument. A tool, such as a rotatable portion of a collar or tool base, or a working instrument operably coupled thereto, is rotatable relative to the interface. The interface and collar have guide channels. A control element extends through the medical instrument and respective guide channels such that the tool or collar is controllably rotatable about the instrument axis by axial movement of the control element relative to the instrument.

  • Patent number: 8391957
    Abstract: A robotic instrument system having an elongate sheath instrument and an elongate catheter instrument positioned within a working lumen of the sheath instrument is controlled by selectively operating an instrument driver coupled to the catheter instrument to place a control element extending through the catheter instrument in tension, and thereby articulate at least a distal end portion the catheter instrument, while automatically compensating for a torsional force exerted on the sheath instrument in a first direction due to articulation of the distal end portion of the catheter, by urging the sheath instrument to twist in a second direction opposite of the first direction.

  • Patent number: 8285364
    Abstract: An automated medical system comprises a first instrument assembly including a first ultrasound transducer having a first transducer field of view that transmits and receives ultrasound signals in imaging planes disposed circumferentially about a guide instrument, and a second instrument assembly including a second ultrasound transducer having a second transducer field of view coupled to one of a second flexible guide instrument and a working instrument. A computing system is operatively coupled to the respective first and second transducers and configured to determine a relative spatial orientation of the respective first and second transducers based at least in part on detecting a signal transmitted by one of the first and second transducers and received by the other of the first and second transducers, the received signal having an amplitude indicating the receiving one of the transducers is in the field of view of the transmitting one of the transducers.

  • Patent number: 8270694
    Abstract: A variety of embodiments relate to systems, methods, circuits and devices are implemented to perform location-based correlations. One such embodiment relates to a circuit-implemented method for use with an actual probe within an anatomical structure. For a virtual probe at a virtual location within a model of the anatomical structure, virtual image data captured by the virtual probe is generated. The virtual image data is assessed through a probabilistic comparison of the virtual image data to actual image data captured by the actual probe at an actual location. Based upon the assessment, a correlation is updated between the actual location of the actual probe and a sensed location of the actual probe to provide synchronicity between the sensed location and actual location. For maintaining the synchronicity between a subsequently sensed location and subsequent actual location, the assessment is used to select a new virtual location for the virtual probe.

  • Patent number: 8190238
    Abstract: A method for performing an interventional procedure using a robotically controlled guide instrument coupled to an instrument drive assembly, includes manipulating a user interface of a master controller to actuate the drive assembly and thereby position a distal portion of the guide instrument at an interventional procedure site in a patient's body; and providing on a first display a graphically rendered image of the distal portion of the guide instrument overlaying an image of the interventional procedure site, wherein manipulation of the user interface causes a corresponding movement of the instrument model relative to the image in the first display.
