  • Patent number: 8020503
    Abstract: A system and method for assembling a prosthetic heart valve, including a procedure for sewing fabric around a heart valve support stent. The system includes a support stent handling component that works in conjunction with a sewing machine component. The sewing machine has a bobbin, and the system includes a non-contact sensor to monitor the passage of a needle thread loop over the bobbin. The sensor may be a monitoring laser, and a controlling processor receives information therefrom for 100% real-time inspection of each stitch. The occurrence of an unsuccessful stitch may prompt the processor to repeat the stitch at a slower speed. The automation of the fabric sewing procedure greatly enhances manufacturing throughput and reduces ergonomic strain on workers.
