Abstract: The invention describes catheter systems and methods for accessing the brain during endovascular/neurointervention procedures in the treatment of ischemic stroke. More specifically, a multi-axial catheter system and kit is described that improves the process of accessing a carotid artery particularly in patients having a tortuous aortic arch and thereafter improves the process of gaining access to the brain to enable the insertion of aspiration and/or the deployment clot retrieval devices. In addition, methods of utilizing these systems are described.

Abstract: The invention describes catheter systems and methods for accessing the brain during endovascular/neurointervention procedures in the treatment of ischemic stroke. More specifically, catheter systems are described that enable quicker and improved access to cerebral vessels as well as improved processes of accessing and aspirating blood clots from the cerebral vessels of a patient with acute ischemic stroke due to medium or large vessel occlusion.

Abstract: Systems and methods for collecting medical data in a pre-hospital setting are described. Modular study devices (MSDs) are comprehensive, customizable toolkits that provide tools/equipment to enable data collection and particularly the tools/equipment to conduct a particular medical study in the pre-hospital setting. Specifically, the equipment and processes allow for standardized data collection and facilitate operating procedures alongside routine clinical care, thereby streamlining study workflow and pre-hospital treatment steps by emergency medical services (EMS) personnel such as paramedics. In addition, systems and methods are described enabling the efficient design of MSDs that may be configured into medical transport vehicles to meet parameters of those vehicles such as volume and/or weight restrictions whilst enabling a customized or unique study protocol to be conducted in the pre-hospital setting.

Abstract: The invention describes catheter systems and methods for accessing the brain during endovascular/neurointervention procedures in the treatment of ischemic stroke. More specifically, a catheter system having a deployable redirection device (RD) is described that improves the process of accessing a clot in a patient with acute ischemic stroke due to large vessel occlusion.

Abstract: The invention relates to systems and methods to assist physicians in decision making for stroke patients. In particular the systems and methods can be used to assist physicians to decide on whether a patient with an acute ischemic stroke has a large vessel occlusion (LVO) and should be transferred from a community hospital to a larger hospital to undergo an endovascular thrombectomy procedure.

Abstract: Systems and methods for accessing small arteries for conveying catheters to target vessels such as brain vessels are described including systems enabling a catheter to be introduced directly through a vessel opening without an external sheath wherein a distal tip of the catheter is protected by a protective cover. Methods of introducing catheters into vessels and kits are also described.

Abstract: A distal entry point (DEP) to brain aspiration (D2BA) catheter for use in an endovascular procedure for gaining access to cervical and cerebral arteries in a brain of a patient and aspirating one or more intracranial clots from the cerebral arteries, comprising a soft distal tip region having a distal length sufficient to extend from a level 1 or level 2 arterial segment of a cerebral artery or equivalent to an upper neck arterial vessel, a stiffness enabling movement through the level 1 or level 2 arterial segment of the cerebral artery, and an outside diameter (OD) of 6F-10F, a proximal region having a stiffness greater than the stiffness of the soft distal tip region, the proximal region having a length sufficient to extend to outside the patient through the DEP.

Abstract: Methods and apparatus for retrieving a blood clot are disclosed. The apparatus comprises an expandable wire frame for deployment using a push wire within a microcatheter. When deployed in the vicinity of a blood clot, the wire frame is configured to expand and trap the blood clot allowing the blood clot to be removed. The expandable wire frame is connected to the push wire at distal and proximal ends. One or more expansion stops define a minimum distance between the distal and proximal ends of the expandable wire frame and a point of maximum extension of the expandable wire frame. This may help the user to control the configuration of the apparatus as it is being used within the vascular system.

Abstract: The invention relates to systems and methods to improve perfusion flow and pressure during endovascular intervention. In particular, the invention relates to catheters that enable both antegrade and retrograde flow through the catheter during a recanalization procedure and specifically at the step in a procedure where a clot is being withdrawn. Additionally, the invention provides systems for supplying fluids and fluid compositions to improve nutrition to ischemic brain.

Abstract: The invention relates to systems and methods for diagnosing strokes. In particular, systems and methods for acquiring timely patient status information are described that enable a physician to make diagnostic and treatment decisions relating to strokes. The systems and methods enable the efficient and quantitative assessment of arterial collaterals within the brain for aiding these decisions in the case of ischemic strokes.

Abstract: Systems and methods for preparing and completing surgical and medical procedures. In particular, kits are provided for improving preparation and completion time for a medical or surgical procedure in which the kit includes modularized compartments containing sterilized medical or surgical equipment and wherein the medical or surgical equipment is organized and/or ordered within the kit to generally correspond to the sequence of steps of the medical or surgical procedure. The kit is particularly applicable to recanalization procedures for stroke patients as well as revascularization procedures for acute myocardial infarction patients where a kit enables faster preparation and completion of these procedures.
