Abstract: An embolic protection device may include an inflatable embolic balloon with one or more embolic capture elements located at or around its outer surface. The balloon may be inflatable so as to move the one or more embolic capture elements near or against the wall of a vessel. Emboli, and particularly emboli that are relatively more diffuse, softer, more friable, contain more inflammatory cells, and/or may lack fibrous caps, are captured or stopped by the one or more embolic capture elements as blood passes through the one or more embolic capture elements.

Abstract: The present invention discloses an aneurysm treatment device comprising a stent portion and an aneurysm filling portion expanding from an outer side of the stent portion. The device provides a novel approach to treating aneurysms by combining the structural support of a stent with an expandable filling portion to effectively address the needs of patients with aneurysms. The unique design of the device allows for precise placement and expansion within the aneurysm, providing stability and support while promoting healing and recovery. The device offers a versatile and minimally invasive solution for the treatment of aneurysms, improving patient outcomes and reducing the risks associated with traditional treatment methods.

Abstract: An implantable embolic device having a stretch-resistant member passing therethrough that also serves as a tether for connecting the device to a delivery system. The stretch-resistant member is attached at a proximal and distal end of the device and extends proximally to the delivery device. The proximal attachment point serves to isolate a distal, stretch resisting segment of the member from axial tension placed on a proximal, connecting section of the member. Thus, the portion of the stretch-resistant member being used to connect the embolic device to a delivery device may be placed under tension without placing tension or distorting the implant.

Abstract: A multi-cavity aspiration device for more efficiently aspirating multiple obstructions, clots, thrombi, emboli, or the like in a single aspiration stroke. The multi-cavity aspiration device may include a tubular member having an inner circumference. One or more cavities may be formed or cut into the inner circumference of the tubular member so as to increase surface area without affecting structural integrity. The one or more cavities may be positioned radially about the inner circumference of the lumen. The one or more cavities may be tapered proximally and terminate at a point. The one or more cavities may be exposed to the internal lumen of the tubular member.

Abstract: A device may include an elongated catheter body having a proximal portion and a distal portion, wherein the distal portion forms a memorized shape when unconstrained; the memorized shape comprising a plurality of curves positioned to orient the distal portion within a right subclavian artery or brachiocephalic artery and also into a left common carotid artery.

Abstract: A device for treatment of a vascular defect within a patient’s vasculature includes a self-expanding permeable shell having a proximal end, a distal end, and a longitudinal axis, the shell comprising a plurality of elongate resilient filaments having a braided structure, wherein the filaments are secured at at least one of the proximal end or the distal end of the permeable shell, wherein the permeable shell has a radially constrained elongated state configured for delivery within a microcatheter and has an expanded state with an axially shortened configuration relative to the radially constrained state, the permeable shell having a plurality of openings formed between the braided filaments, wherein the permeable shell in its expanded state comprises a plurality of circumferentially-arrayed lobes.

Abstract: A detachment system for an implant is described having a first detachment mechanism and a second detachment mechanism. Either or both of the first or second detachment system may be activated by the user depending on certain conditions or if one of the detachment mechanism fails.

Abstract: Catheters are described that have improved flow characteristics that may be particularly helpful when delivering embolic agents within a blood vessel. One catheter includes a fluid flow modifier that is configured to create laminar fluid flow out of a distal end of the catheter to help reduce turbulence and achieve predictable fluid movement. Another catheter includes scavenging ports that are configured to suction in embolic agents that have refluxed proximally back from a distal end of the catheter.

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: An obstruction removal device is described, having one or more engaging members which can engage portions of the clot. The one or more engaging members have a collapsed, delivery state, and an expanded, deployed state.

Abstract: Described herein is a braided stent having have a plurality of different segments that can reduce or eliminate foreshortening and allow the proximal end of the stent to more reliably open when deployed in a curved vessel. The segments can be connected together by interlocking loops positioned at the end of each segment and can be formed of one or more radially progressing wave patterns.

Abstract: Lubricious coatings for medical devices and their uses are described.

Abstract: A stent with varying porosity is described. The stent can be comprised of multiple stents attached together. A braided stent may have selected regions of increased thickness. The stent may be comprised of wires that are welded together at their ends in order to minimize vessel trauma. The stent may comprise a helically wound radiopaque wire wound through the stent.

Abstract: Described herein is a liquid embolic delivery device designed to minimize excess embolic solvent buildup therein. The liquid embolic delivery device generally comprises an outer catheter, an inner catheter that is longitudinally moveable within the outer catheter. The inner catheter is used for an initial embolic solvent flush and to deliver liquid embolic, while the outer catheter is used to remove excess solvent.

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.
