Distal embolic protection devices with a variable thickness microguidewire and methods for their use

摘要: A distal embolic protection device for dedicated use in cerebral arterial blood vessels is described. The comprises a variable-thickness micro-guidewire and collapsible filtering mounted on the microguidewire over two mobile attachment points so that its collapsed configuration, thickness of at this region less than or equal to 0.017 inch (0.432 mm) be able pass through existing conventional microcatheters. allow rotatory longitudinal mobility while stable thereby decreasing risk trauma fragile vessels. Preferably, an expansion assembly, e.g., plurality struts attached filter membrane are folded position which self expand desired dimensions within Also described methods using devices invention.
