From the outside, Salina Gonzales looks pretty much like any other shopper — but it's what's going on inside her body that is so remarkable.
A revolutionary electric pump, sewn to Gonzales' heart, keeps blood flowing through her body. The pump spins at 10,000 rotations a minute, and the device has kept her alive, ever since her heart grew dangerously weak more than a year ago.
"It was very difficult. I couldn't walk two steps without being severely short of breath," Gonzales said.
