Abstract
The invention relates generally to methods and systems for capturing, filtering, or retrieving obstructions or other particulates from a patient's vasculature. In one aspect, a device for retrieving an obstruction from a patient is provided that includes an outer delivery shaft and an expandable basket movable between a collapsed configuration and an expanded configuration. The basket is configured to be in the collapsed configuration during delivery and in the expanded configuration during engagement and retrieval of the obstruction. A proximal end of the basket is configured to be centrally and pivotally coupled to the outer delivery shaft. The proximal end and/or a distal end of the basket is movable relative to each other such that a proximal portion of the expandable basket is invertible toward a distal portion of the basket to form a proximally oriented cavity in the expanded configuration to engage and retrieve the obstruction.
