A Spray Device for Damaged Heart

Mechanical engineer, Dr Suwan Jajasinghe at UCL, has developed a spray device that can deliver viable heart cells to a damaged heart.  To control the movement of the cells through the spray needle, 10 000 volts of electricity are applied.  According to the British Heart Foundation, the hope is that this device could find application in conditions that destroy heart tissue such as myocardial infarction (heart attack).  The next major milestone for this device would be clinical trials.
