Abstract

Novel cerebral vasculature devices are disclosed, including thrombectomy removal devices that include a continuous braided structure, a proximal portion, a distal portion, and a first expandable portion located between the proximal portion and the distal portion. The braided structure includes a plurality of wires. The proximal portion and the distal portion include polymer imbedded at least partially into the braided structure. The device is useful for removing thrombus from a patient's vasculature.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to devices useful for removing objects such as thrombus / or other foreign bodies from a patient's vasculature. More particularly, the invention relates to devices useful for removing thrombus from a patient's cerebral vasculature.

[0003] 2. Description of Related Art

[0004] The use of a mechanical means to restore patency to obstructed vessels is well known. These devices fit into many categories ranging from hydraulic removal of thrombus, rotating cutting blades for calcified plaque, inflatable means for crushing or dragging thrombus, or a multiplicity of metal structures that either self-expand or can be expanded to dredge a vessel or remove a stone.

[0005] Examples of these devices date back to the ‘Fogarty Catheter’ described by Fogarty in U.S. Pat. Nos. 3,367,101; 3,435,826; and 4,403,612 describing in detail improvements to a balloon catheter for embolectomy purposes. While suitable for many...
