An atherectomy device is disclosed herein. The atherectomy device includes a first drive shaft, a second drive shaft, a handle assembly, and a cutting member. The first drive shaft extends distally from the handle assembly and includes the cutting member mounted on a distal end region of the first drive shaft. The second drive shaft extends distally from the handle assembly to a distal end of the second drive shaft such that both the first and the second drive shafts are rotatable relative to the handle assembly, and the first drive shaft is rotatable independent of the second drive shaft.
