Abstract
Apparatus and method for detecting the presence of friable atheromatous deposits in or near the aortic arch of a patient. Fluid aspirated from the aorta in the region of the inner curvature of the transverse arch and the descending aorta through a cannula attached to a handle is drawn by suction through a filter in the handle, and any particulate is trapped for determining the presence of atherosclerotic plaque. A manually operated valve in the handle controls the suction and an elastomeric check valve prevents fluid backflow.
