Abstract
A method of capturing and macerating particles in a blood vessel is provided. A vascular filter device is implanted in the blood vessel at a treatment site. The vascular filter device comprises a filter body and an agitation member disposed within the filter body. Movement of the agitation member acts on particles trapped within the filter body for enhancing the dissolution of the particles, thereby reducing the likelihood of filter occlusion and improving the flow of blood through the vessel. The vascular filter device is preferably collapsible for percutaneous delivery to a treatment site. The agitation member is preferably rotatably coupled to the filter body. A power source is provided for moving the agitation member. In various examples, the power source may take the form of an energy storage device, a drive catheter, or a magnetic field.
