  • Publication number: 20170143942
    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.

  • Publication number: 20170035594
    Abstract: The present disclosure provides a support device for a gastrointestinal implant. The support device may include a lumen configured to extend through a submucosal tunnel and a mouth located at a proximal end of the lumen and in fluid communication with the lumen. The mouth may be configured to face proximally within a gastrointestinal tract to receive GI contents, and the mouth may be configured to direct the GI contents into the lumen. The support device may further include a support structure, where the lumen extends through the support structure, and where the support structure is configured to apply an outward radial force on an inner wall of the gastrointestinal tract. An artificial tunnel may extend distally from the support structure, may form at least a portion of the lumen, and may be configured to extend through the submucosal tunnel.
