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: 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 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 distal aspiration catheter comprises a catheter body having a central lumen, at least one distal opening and a distal tip positioned distally to the at least one distal opening. An aspiration source is configured to attach to a proximal end/luer hub of the central lumen. When the aspiration source is activated, a clot/emboli lodged in a blood vessel is partially ingested into the at least one distal opening of the catheter body by the application of a static aspiration force. The aspiration source may activate a cyclic aspiration force with a forward pressure flow to induce clot fatigue into the partially ingested clot. The fatigued clot can be collected inside the distal tip of the catheter and be removed completely by a single pass of the distal aspiration catheter.
