My mom has had 2 massive heart attacks. Doctor Robert Baldwin did a Double Mirtiral Valve Replacement. She has been in the hospital at SouthWest Memorial Hospital in Houston Texas for the past month. She recalls a show of yours talking about a special instrument used to locate veins. Being that her veins in her arms and hands have all been used for multipile reasons, she would like to know if this instrument could be used to assist her.

Thank you,
