Abstract
An atherectomy device including a handle configured to be manipulated by a user. The device further includes a catheter comprising an outer sheath and a drive shaft carried within and rotatable relative to the outer sheath. A cutter assembly is coupled to and extends distally relative to the outer sheath. The cutter assembly includes a housing coupled to and extending distally from the outer sheath. A proximal cutting element is rotatably carried by the housing, and the proximal cutting element is coupled to and extends distally from the drive shaft. The proximal cutting element includes a cutting stem having at least one cutting feature and at least one cutting blade coupled to the cutting stem. A distal cutting element is carried by the cutting stem and is rotatable with the proximal cutting element relative to the housing. The distal cutting element includes at least one cutting blade.
