Atherectomy devices were developed as a mechanism of physically removing plaque from the lesion itself. The first two devices invented were the directional atherectomy device and the transluminal extraction catheter (TEC). In the early 1980’s David Auth investigated the use of a rotational device as a mechanical alternative in debulking atherosclerotic plaque. 11. Ahn S.S., Auth D., Marcus D.R., Moore W.S.

Link This rotational atherectomy system, known as Rotablator® was commercialised by Heart Technology, received FDA approval in 1990 for use in peripheral arteries, and in 1993 for coronary arteries. It was subsequently acquired by Boston Scientific (Natick, MA, USA) in 1996, who continue to market and support the product worldwide.

Principles of rotational atherectomy

The Rotablator rotational atherectomy system was developed according to two principles. Firstly, the device preferentially ablates hard calcific atherosclerotic plaque...
