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.

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.

Abstract: A medical device is disclosed and may have a spiral shape structure that can function as a stent, such as a flow diversion stent to treat aneurysms. The medical device may have a spiral shape structure that can function as an occlusive device, for instance to occlude aneurysms. The medical device may include a shape setting structure to selectively adjust the shape of the medical device.

Abstract: Devices and methods for treatment of a patient's vasculature are described. Embodiments may include a permeable implant having a radially constrained state configured for delivery within a catheter lumen, an expanded state, and a plurality of elongate filaments that are woven together. The permeable implant may include a stiffer proximal portion that is configured to sit at the neck of an aneurysm. The stiffer proximal portion may include coils, stiffening elements, or reinforcement elements disposed about or associated with the filaments or woven together with the filaments.

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.

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.
