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: 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: The present disclosure relates to medical devices including occlusion devices, clot retrieval systems, and stents. More particularly, the medical devices described herein measure characteristics for intravascular treatment sites. The medical devices may include pressure sensors and/or length sensors that may be used to determine the effectiveness of the medical devices during or after treatment. These sensors may be particularly helpful when used on an occlusion device or a clot removal device.

Abstract: A distal aspiration catheter comprises catheter body having a central lumen and at least one luminal channel. An aspiration source is configured to attach to a proximal end/luer hub of the central lumen. Each luminal channel includes one mandrel and a distal portion of the mandrel extends into a distal portion in the central lumen. When the aspiration source is activated, a clot/emboli lodged in a blood vessel is partially ingested into the distal portion of the central lumen. The distal portion of the mandrel can move into the partially ingested clot to induce clot fatigue. The fatigued clot can be removed completely by a single pass of the distal aspiration catheter.
