Riyaz Bashir was frustrated with the tools he had to treat blood clots in the lungs. So the Temple University Hospital cardiologist invented a new device to treat the nation’s third leading cardiovascular cause of death.invention. Bashir believes the device is a significant milestone in the treatment of pulmonary embolism, which occurs when a blood clot gets stuck in one of the arteries in the lung. Blood then can’t reach the oxygen it needs to carry to the heart, brain and the rest of the body.

The arteries in the lung are much larger, and so are the clots that get stuck in them.
