Abstract
An improved arterial catheter device for capturing emboli within the aorta and other arteries is described. The system typically includes an elongated catheter member bearing a filtration apparatus disposed at its the distal region, comprising a filter membrane and a mechanism for deploying and collapsing the filter. For reliable deployment, the deployment mechanism comprises at least one pair of struts, one being a compression strut and the other a tension strut. In use, the catheter is positioned so that the filter membrane is down stream from the possible embolic source and upstream from any vital organs of concern. When deployed the filter membrane will capture emboli from the blood stream, and upon filter removal will extract the emboli from the patient.
