Abstract

A burr (100) for rotational ablation atherectomy devices having micro-engineered cutting features. The burr includes a plurality of stacked cutting disks (120) that are attached to a back support element (110). The back support element is rotationally coupled to a drive shaft (22) of the atherectomy device. The stacked cutting disks include a keyed center hole, and a plurality of outwardly-oriented cutting teeth. The cutting disks (120) are varying outer diameter and are arranged to produce the desired burr shape. In one embodiment, a center mandrel (130) having a body portion slidably engages the keyed center holes of the stack of cutting disks, and connects to the back portion (110), thereby locking the cutting disks in place. In one disclosed embodiment, spacing disks are inserted between pairs of adjacent cutting disks (120). The spacing disks have a diameter less than the diameter of the adjacent cutting disks, thereby cooperatively with the adjacent cutting disks forming a circumferential channel in the burr. It is empasized that this abstract is intended to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of meaning of the claims pursuant to 37 C.F. R. 1 72 (b).
