  • Patent number: 10814109
    Abstract: A method may include accessing an artery in communication with an ophthalmic artery of a subject, and advancing a microcatheter along the accessed artery so as to align a distal end of the microcatheter with an ostium of the ophthalmic artery, wherein the microcatheter includes a lumen having a guidewire positioned therein. In addition, the method includes proximally withdrawing the guidewire relative to the microcatheter so as to enable a distal portion of the microcatheter to assume a curved relaxed configuration, and cannulating the ostium with the distal portion of the microcatheter when the distal portion is in the curved relaxed configuration.

  • Patent number: 10773383
    Abstract: A method and a system stream robot tool center point position to external processors at high frequency. The method includes the steps of: reading robot joint encoder data using an Interrupt Service Routine in the robot controller; calculating tool center point position based on the encoder data; and sending the calculated position data to a network socket in a high priority task. The method achieves tool center point and/or joint position communication at fast and consistent time intervals, as compared to much longer times for prior art methods. A downstream device, such as a processor or controller for another machine, reads the communicated tool center point and/or joint position data and uses it to control the operations of its own device. High speed motion command streaming from outside processors can be used in a similar way to control the robot.

    Abstract: Interventional catheter assemblies that operate over a guide wire are disclosed. Specifically, an elongated flexible catheter is associated at its proximal end with a housing having a guide wire port where the guide wire exits the housing. The housing additionally incorporates a guide wire brake mounted within a slot positioned a distance from the guide wire port for engaging and releasing a guide wire. The slot is generally arranged at an angle to the path of the guide wire as it exits the guide wire port. When the guide wire is clamped in the angled slot, variable lengths of exposed guide wire accumulate in a substantially unrestrained condition when the flexible catheter is advanced and retracted relative to the guide wire, allowing movement of the distal end of the catheter over considerable distances without repositioning and re-clamping the proximal end of the guide wire.

  • Patent number: 9039603
    Abstract: A propulsion apparatus for an endoscope includes a propulsion assembly for mounting on a tip device of the endoscope, for propulsion in a body cavity. First and second wire devices are disposed to extend from the tip device in a proximal direction, having a coil winding, for rotating to drive the propulsion assembly. First and second motors are connected with proximal ends of respectively the first and second wire devices, for rotating the first and second wire devices. A timer is actuated if a speed difference between rotational speeds of the first and second motors becomes equal to or more than a reference speed value, for measuring an elapsed time. A break detector detects breakage of the first wire device if the elapsed time becomes equal to or longer than a predetermined time. A controller controls the first and second motors in response to an output of the break detector.

  • Patent number: 9017283
    Abstract: A catheter adapted for ablation, mapping, injection, and directional control by an external magnetic system has a catheter body, an intermediate section, and a tip section having a tip electrode configured with an omnidirectional distal end and a concentric needle port. The tip electrode houses a magnetic device and a position sensor arranged in an integrated configuration, wherein the configuration facilitates a path in the tip section for a component, including an injection needle, to extend through the tip section for extension and retraction with reduced stress and friction. The integrated configuration is an efficient use of space in the tip electrode that allows the tip section to carry both the position sensor for determining location and orientation of the tip section and the necessary volume of magnetic or magnetizable material to accomplish magnetic navigation.
