  • Patent number: 12343255
    Abstract: The disclosure relates to heart have prostheses with the reduced need of pacemaker implantation and improved means for positioning the replacement heart valve. In one aspect of the present disclosure, the stent scaffold of the valve prosthesis includes axially extending locators. The locators may be positioned within the cusp of the native aortic valve. Placement of the locators within the cusps may prevent further proximal movement of the stent scaffold into the left ventricle. By adjusting the location of the proximal end of the locators with respect to the proximal end of the stent scaffold, infra-annular placement of the stent scaffold in the aortic annulus may be assured. In another aspect, means for visualizing the positioning of replacement heart valves at an implant site inside an individual's body is disclosed.

  • Publication number: 20240325176
    Abstract: A vascular prosthesis (e.g., stent), and packaging and delivery system to selectively deliver a vascular prosthesis are described. In some embodiments, the vascular prosthesis utilizes a low porosity and high porosity section, and the packaging and delivery system allows the prosthesis to be delivered such that the position of the low porosity and high porosity sections of the prosthesis can vary.

  • Publication number: 20240315712
    Abstract: Aspiration thrombectomy devices and methods wherein an aspiration cycle includes a positive displacement segment to facilitate clot removal, a pump cartridge to facilitate tube management and an aspiration device for providing a vacuum surge. Disclosed herein is an aspiration thrombectomy system which relies on air or inert gas, rather than liquid, to provide both static and dynamic suction level profiles for safely and efficiently retrieving and removing from the body a thrombus. In one example embodiment, two or more pressure sources may be configured to apply two or more suction levels to an aspiration catheter. Valves may connect conduits between the pressure sources and the aspiration catheter, with the valves being selectively opened or closed to control which pressure level is applied to the catheter.

  • Publication number: 20230329888
    Abstract: A stent, a stent delivery system, and a method of delivering a stent are described that allow the porosity of the stent to be changed dynamically during a delivery procedure. Unlike prior stents and procedures that are configured to deploy with a predetermined porosity, the physician can create a region of high stent porosity over certain vessel features, a low stent porosity over other vessel features, and can create these porosity changes with at least one stent or stent layer.

  • Publication number: 20230252631
    Abstract: A neural network apparatus receives, as input from a user device, digital imaging information and the clinical information for an aneurysm patient and generates, using a neural network trained for aneurysm outcome prediction, the digital imaging information, and the clinical information, an outcome prediction for at least one intrasaccular implant device for implant in an aneurysm sac identified in the digital imaging information and having a highest predicted likelihood of complete occlusion of the aneurysm sac from a set of potential treatment devices. The apparatus is further configured to output, for display on a device, an identification of the at least one intrasaccular implant device and the outcome prediction for each of the at least one intrasaccular implant device.
