Abstract
Apparatus and methods for aspirating emboli from a vascular filter or stent within a patient's circulatory system are provided. A filter sac of the vascular filter permits blood flow and captures emboli from the flow. The aspiration device removes emboli from within or proximal to the vascular filter or stent to reduce the risk to the ischemia during retrieval of the vascular filter and during a treatment procedure. Retrieval of the vascular filter may be accomplished using either the aspiration catheter or a separate retrieval catheter.
