Injection moldable feedstock including diamond particles for abrasive applications

An atherectomy burr, comprising:

• a burr body adapted to be coupled to a driveshaft that is rotated in a patient's vessel to remove an occlusion, the burr body being made of diamond particles that are combined with a binding material that holds the diamond particles in a solid form.

An atherectomy buff comprising:

• a burr body adapted to be coupled to a driveshaft that is rotated in a patient's blood vessel, the burr body being made of diamond particles and a binding means for forming the diamond particles into a solid, the burr body having an abrasive outer surface that removes the deposits in a vessel when rotated by the driveshaft.

An atherectomy burr for removing deposits from a vessel, including:

• a burr body having an abrasive outer surface, the burr body being coupled to a drive shaft and rotated in a vessel to remove deposits:
• the burr body having a thermally conductive composite for removing heat from the site at which deposits are removed from the vessel.
