Abstract: A valve insertion device for traversing a wire guide through a valve within an intraluminal passage. A wire guide is positioned near the outflow of a valve within an intraluminal passage. Alongside the wire guide, a pressure sensor is positioned to detect the pressure of the fluid in the intraluminal passage. As the valve opens, the fluid pressure at the outflow of the valve increases. This information is sent from the pressure sensor to a control system. From this information, the control system can determine when the valve will open and can actuate an advancement system to move the wire guide to traverse the open valve. After traversing the valve, various catheters and sheaths may be advanced over the wire guide through the valve.

Abstract: A left atrial appendage shunt for reducing blood clot formation in a left atrial appendage includes a first artificially created opening through a wall of the left atrial appendage and a second artificially created opening through a wall of a target cardiovascular structure. A circulation conduit fluidly connects an interior of the left atrial appendage and an interior of the target cardiovascular structure, and has a first end opening at the first artificially created opening and a second end opening at the second artificially created opening.
