The final product is constructed of polyethylene terephthalate, a standard medical plastic, and weighs less than 5g. It can be sutured directly into place by a surgeon at relatively low cost. The results speak for themselves: Golesworthy was the first recipient of his own creation, and since then, 23 others have taken the plunge, with more on the waiting list. Golesworthy sees this as not just a victory for Marfan sufferers, but a message to the medical community: "They are all biologists and medics, and they need process engineers," he said. Golesworthy wants a greater collaboration amongst the medical community and engineers, who could see solutions the doctors and biologists can't. Hopefully the medical community is listening--he's his own proof, after all.
