  • Patent number: 11590319
    Abstract: For robotically operating a catheter, a medical catheter is controlled by rotation of the catheter as well as steering in one or more planes of a distal end of the catheter. To robotically rotate the catheter, a handle is rotated. The steering is performed separately using one or more knobs on the handle. The rotation of the handle complicates the robotic control of the knob. A mechanical decoupling is used so that rotation of the handle maintains the position of the knob relative to the handle. Gearing or transmission is used to avoid independent control of the knob and handle rotation. In an alternative or additional approach, the handle may be robotically controlled while also guiding the catheter shaft spaced away from the handle, allowing fine-tuned control of the catheter at the access point to the patient.

  • Patent number: 11589858
    Abstract: A method is disclosed. The method includes providing a plurality of blades, movably connecting the plurality of blades to an outer member via a plurality of arm members, disposing the plurality of blades in a human or animal body, and moving the plurality of blades from a first position outward to a second position when the plurality of blades are disposed in the human or animal body. The plurality of blades are disposed further from each other in the second position than the first position. Moving the plurality of blades outward from the first position to the second position includes moving the plurality of arm members. Moving the plurality of blades includes maintaining equidistance between the plurality of blades as the plurality of blades move from the first position to the second position.

  • Patent number: 11583243
    Abstract: A system for deploying needles in tissue includes a controller and a visual display. A treatment probe has both a needle and tines deployable from the needle which may be advanced into the tissue. The treatment probe also has adjustable stops which control the deployed positions of both the needle and the tines. The adjustable stops are coupled to the controller so that the virtual treatment and safety boundaries resulting from the treatment can be presented on the visual display prior to actual deployment of the system.

  • Patent number: 11576720
    Abstract: A method for use with an intra-body probe, a distal end of which includes an ablation electrode and a temperature sensor, is described. While (i) the ablation electrode is driving an ablating current into tissue of a subject, and (ii) fluid is passed from the distal end of the intra-body probe at a fluid-flow rate, a processor receives a temperature sensed by the temperature sensor. The processor estimates a temperature of the tissue, based at least on the sensed temperature and at least one parameter selected from the group consisting of: the fluid-flow rate, and a parameter of the ablating current. The processor generates an output in response to the estimated temperature. Other embodiments are also described.

  • Patent number: 11571212
    Abstract: A surgical stapling system comprising an end effector, a firing member, a motor, and a control system is disclosed. The end effector comprises an elongate channel, a staple cartridge, and an anvil. The staple cartridge comprises staples removably stored therein. The elongate channel and the anvil are configurable in a closed configuration to capture tissue therebetween. The anvil comprises an impedance sensor configured to sense an impedance of the tissue. The firing member is moveable between a starting position and an ending position. The staples are deployable from the staple cartridge based on the firing member moving toward the ending position. The motor is configured to drive the firing member toward the ending position. The control system comprises a multiplexer configured to control the impedance sensor. The control system is configured to interrogate the impedance sensor to determine the impedance and control the motor based on the determined impedance.

  • Patent number: 11564738
    Abstract: A method for ablating a patient, consisting of ascertaining a CHA2DS2-VASc score for the patient and inserting a probe into the patient, so as to contact a pulmonary vein of the patient. The method further includes applying energy via the probe so as to ablate the pulmonary vein until pulmonary vein isolation (PVI) is achieved. When PVI is achieved and the CHA2DS2-VASc score is less than a preset value, ablation of the pulmonary vein is ceased. When PVI is achieved and the CHA2DS2-VASc score is greater than or equal to the preset value, energy is applied to perform a further ablation.
