  • Patent number: 11426192
    Abstract: A capturing unit provided on a distal end of a second tube can be deformed into a contracted state and an expanded state, in which the capturing unit is deployed to form a capturing chamber. The capturing chamber has an opening area decreased as it goes from a distal end opening of the capturing chamber toward a proximal end opening of the capturing chamber. A third tube rotatable relative to the second tube and a cutting unit provided on a distal end of the third tube for cutting a foreign substance are arranged in a second lumen. In the expanded state of the capturing unit, the cutting unit is arranged more toward the proximal end opening of the capturing chamber than the distal end opening.

  • Patent number: 11382650
    Abstract: A method for capturing an object in a cavity in a patient is described. The method includes advancing a ureteroscope into the cavity containing the object. A basket is advanced through a working channel of the ureteroscope. The basket is opened within the cavity and is positioned so as to enclose the object. Then, two actions are performed simultaneously. The basket is collapsed while simultaneously the basket tool is advanced forward so that the object remains within the basket, ideally near the center of the basket, as the basket closes around the object. Once the object is captured, the basket is retracted to remove the object out of the cavity. Further, this process may be automated by having the method carried out by robotic arms acting in tandem, with one or more robotic arms advancing the basket tool or ureteroscope, and another robotic arm collapsing the basket.

The thrombus filter assumes a second position when the thrombus intercepting net is retrieved into the sheath, where the umbrella surface converges towards the center of the intercepting port, and the open end of the umbrella surface is constricted to prevent the thrombus from escaping.

  • Patent number: 10653859
    Abstract: Disclosed herein is a delivery catheter for implanting a leadless biostimulator. The delivery catheter includes a shaft and a tubular body having a lumen and an atraumatic end. The atraumatic end includes at least one of a braided, woven or mesh construction configured to facilitate the atraumatic end changing diameter. When a distal portion of the shaft is coupled to a proximal region of the leadless biostimulator, at least one of distally displacing the tubular body relative to the shaft or proximally displacing the shaft relative to the tubular body causes the leadless biostimulator to be received in the volume of the atraumatic end and the atraumatic end to encompass the leadless biostimulator. Conversely, at least one of proximally displacing the tubular body relative to the shaft or distally displacing the shaft relative to the tubular body causes the leadless biostimulator to exit the volume of the atraumatic end.
