  • Publication number: 20210196320
    Abstract: In some embodiments, a method includes a shaft having a side catheter guide attached thereto via a guide coupler into an inferior vena cava and a superior vena cava such that the guide coupler is disposed in a right atrium, and applying a distal force to a proximal portion of the side catheter guide such that a distal end of the side catheter guide deflects laterally about the guide coupler towards a septum. The method further includes extending a side catheter that is disposed within the side catheter guide distally from the side catheter guide towards and into contact with the septum. The method further includes, with the side catheter in contact with the septum, extending a septum penetrator that is slidably disposed within the side catheter distally from the side catheter such that the septum penetrator pierces the septum.

  • Publication number: 20210169486
    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: 10179029
    Abstract: A method of performing denervation with a cooled microwave denervation catheter assembly includes advancing a catheter body over a guide wire in a body lumen of a patient to a treatment location adjacent targeted nerves, with the guide wire being located in an interior lumen of the catheter body, inflating the balloon with cooling fluid to contact a wall of the body lumen of the patient, removing the guide wire from the interior lumen of the catheter body, and inserting a microwave antenna catheter into the interior lumen of the catheter body, so that denervation treatment may be performed by simultaneously circulating cooling fluid in the balloon and supplying power to the microwave antenna, to cause the targeted nerves to be heated to a temperature sufficient to cause thermal damage while the wall of the body lumen is maintained at a temperature where thermal damage does not occur.
