摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Methods for the diagnosis and treatment of nonstenotic carotid plaques and symptomatic nonstenotic carotid disease (SyNC) are described. In particular, methods of evaluating the presence of unstable plaque/thrombus and methods of treatment that include deploying plaque stabilizers (PSs) into the cerebral vasculature are described. The invention further describes plaque stabilizers, uses of plaque stabilizers and plaque stabilizer kits.

摘要： The invention relates to the treatment of aneurysms, and more particularly to intravascular devices and methods for the occlusion of an aneurysm. The device includes a first portion having an expandable and compressible mesh having dimensions for insertion into and expansion against the wall of an aneurysm and a second disk portion having a flexible, collapsible mesh operatively connected to an outer surface of the first portion and having dimensions for covering an outside of the neck opening. The combination of the first portion and second disk portion have a combined resilient flexibility to effectively bias the second disk portion against the neck opening in a substantially flat manner when the first portion is engaged within the aneurysm.

摘要： The invention generally relates to co-axial stent and catheter systems and medical procedures utilizing these systems. The co-axial stent system is characterized by two-coaxial stents, including an outer resorbable stent and an inner metal stent used to effect deployment of the resorbable stent. The stents may use for treatment of unstable plaque and/or thrombus at the carotid bifurcation and particularly those that are not causing any significant stenosis. The stents may also be used for treatment of cerebral aneurysms. The invention further describes related, equipment, uses and kits for the treatment of unstable plaque and/or thrombus and/or aneurysms.

摘要： The invention describes systems and methods for retrieving blood clots (thrombi) from patients undergoing endovascular/neurointervention procedures following ischemic stroke. More specifically, a preloaded catheter and clot retrieval system (PCS) effective in positioning a clot retrieval system (CRS) or stent adjacent a clot and ensnaring and removing the clot are described as well as methods of utilizing these devices.

摘要： 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.
