Abstract
A removable vascular filter system for capture and retrieval of emboli while allowing continuous perfusion of blood during a cardiopulmonary bypass procedure, comprising a porous filter membrane with variable diameter holes, and a filter membrane support structure. The system may minimize the incidence of stroke, myocardial infarction or other clinical complications that may be associated with cardiopulmonary bypass procedures.
