Abstract
A rotational atherectomy device for abrading a stenotic lesion from a vessel of a patient comprises a flexible drive shaft which extends towards a distal end of the device, a distal fluid inflatable support element located at a distal end of the drive shaft and an abrasive element mounted to the drive shaft proximal to and spaced away from the distal fluid inflatable support element. Both the abrasive element and the distal fluid inflatable support element are rotatable together with the drive shaft and the drive shaft comprises a torque transmitting coil which defines a long lumen of the drive shaft.
