Abstract
The invention is an apparatus and method to perform a surgical procedure within the beating heart. The instrument provides a seal to surround cardiac tissue, thereby defining a segregated surgical field within the body of the instrument. A suction device is preferred to remove blood and fluids from the surgical field so that a surgical procedure can be performed while the heart continues to beat. The instrument is particularly suitable for a procedure to repair defective or diseased cardiac valves, such as the mitral valve; a procedure which previously required that the heart be stopped so that the corrective surgical procedure could be performed.
