The Sunnyvale, CA based company has introduced the TCAR procedure which is intended to reduce the risk embolic debris entering the brain during interventional procedures related to the carotid artery. With the TCAR procedure, a small incision is made just above the collar bone to expose the common carotid artery. A soft, flexible sheath is placed directly into the carotid artery and connected to a system that will reverse the flow of blood away from the brain to protect against fragments of plaque that may come loose during the procedure. The blood is filtered and returned through a second sheath placed in the femoral vein in the patient’s thigh.
The company's prospectus says that more than 4,600 TCAR procedures were performed in 2018. At the end of 2018, more than 7,550 TCAR procedures had been performed globally. The company believes that there are more than 4.3 million people in the US alone with carotid artery disease.
