  • Patent number: 11998440
    Abstract: A stent-graft prosthesis includes a graft material having a tubular construction, a frame coupled to the graft material, and a port or opening disposed between a proximal end and a distal end of the graft material. The port or opening is open during deployment of the stent-graft prosthesis to enable blood flow from a graft lumen within the graft material to exit the graft lumen, and the port or opening is blocked upon full deployment of the stent-graft prosthesis to prevent blood flow from within the graft lumen from exiting the graft lumen through the port or opening.

  • Publication number: 20240033027
    Abstract: An in-situ fenestration device for locating a fenestration site and for forming a fenestration. The in-situ fenestration device includes first and second magnetic locators configured to magnetically mate in a mated position within a vasculature of a patient at the fenestration site. The in-situ fenestration device also includes first and second heating elements configured to heat the first and second magnetic locators to form the fenestration at the fenestration site.

  • Publication number: 20240033472
    Abstract: An in-situ fenestration device including a fenestration catheter extending along a longitudinal axis and a proximal tip extending from the fenestration catheter. The fenestration catheter includes a first articulating element and a second articulating element. The first articulating element is articulable about the longitudinal axis from a delivery state to a deployment state. The second articulating element articulable about the longitudinal axis from the delivery state to the deployment state. The first articulating element and the second articulating element in the deployment state are configured to form a fenestration in a graft material at a fenestration site of a stent graft.

  • Publication number: 20240016632
    Abstract: The present disclosure provides a method including positioning a first guidewire within a primary guidewire lumen of a multi-lumen tapered tip. A second guidewire is positioned within a secondary guidewire lumen and a shared guidewire lumen of the multi-lumen tapered tip, the second guidewire preventing the first guidewire from entering the shared guidewire lumen. A delivery system including the multi-lumen tapered tip is advanced over the second guidewire. By advancing the delivery system over a single guidewire, any possibility of entanglement of multiple guidewires during advancement of the delivery system is eliminated. The method further includes a guidewire exchange including releasing the second guidewire from the shared guidewire lumen, advancing the first guidewire through and out of the shared guidewire lumen, and advancing the delivery system over the first guidewire to a deployment location.

  • Publication number: 20230157762
    Abstract: Disclosed herein are techniques for implementing an intelligent assistance (“IA”) or extended intelligence (“EI”) ecosystem for soft tissue luminal applications. In various embodiments, a computing system analyzes first layer input data (indicating movement, position, and/or relative distance for a person(s) and object(s) in a room) and second layer input data. The second layer input data includes sensor and/or imaging data of a patient. Based on the analysis, the computing system generates one or more recommendations for guiding a medical professional in navigating a surgical device(s) with respect to one or more soft tissue luminal portions of the patient. The recommendation(s) include at least one mapped guide toward, in, and/or around the one or more soft tissue luminal portions. The mapped guide can include data corresponding to at least three dimensions, e.g., a 3D image/video. The computing system can present the recommendation(s) as image-based output, using a user experience device.
