The Angiojet is a very small device that dissolves potentially deadly blood clots in a patient's coronary arteries by delivering a high pressure jet of saline into the artery before the patient undergoes a balloon angioplasty (often with stenting).

By removing the blood clots from the coronary artery before angioplasty/stenting, the Angiojet can greatly reduce the risk of complications such as heart attack or even death.
