  • Patent number: 10695065
    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: 10667817
    Abstract: A system for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.

  • Patent number: 10092286
    Abstract: A suturing end effector includes a first jaw member, a second jaw member, and a helical needle. The first and second jaw members are moveable relative to one another between open and closed configurations. Each of the first and second jaw members defines a first row of wells that define a helical path when the first and second jaw members are in the closed configuration. The helical needle is rotatable through the helical path between retracted and extended positions. The helical needle is configured to draw a suture through tissue between the first and second jaw members when the helical needle is rotatably advanced through the helical path and configured to be independently moveable relative to the suture when retracted from the advanced position to the retracted position.

  • 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.
