  • Patent number: 10070866
    Abstract: A method of creating an anastomosis includes steps of advancing a distal tip of a catheter device through a first blood vessel into a second blood vessel, while simultaneously advancing a proximal base of the device into the first vessel, contacting a wall of the first vessel with a distal blunt surface on the proximal base. A further step is to retract the distal tip so that a proximal blunt base of the distal tip contacts a wall of the second vessel, thereby capturing the two vessel walls between the blunt surfaces of the proximal base and the distal tip. A controlled pressure is applied between the two blunt surfaces to compress and stabilize the captured tissue and approximate the vessel walls. A clip is deployed through the captured tissue to hold the tissue in place during the anastomosis procedure. The anastomosis is created by applying cutting energy to the captured tissue.

  • Patent number: 9737364
    Abstract: A method of actuating a surgical device is described. A surgical tool is inserted into a body cavity of a patient through a natural orifice. A distal end of an actuation tool is inserted through a surgical access port in the body of the patient. The distal end of the actuation tool is positioned proximal to an external wall of the body cavity opposite the surgical tool. A magnetic coupling is established between the distal end of the actuation tool and the surgical tool. When the magnetic coupling is established, distal end of the actuation tool is located at the external wall of the body cavity and the surgical tool is located at the internal wall of the body cavity. The surgical tool is manipulated using the actuation tool through the magnetic coupling.
