During preparation for a thrombectomy, the physician placed a non-penumbra bleedback control valve on the proximal end of a penumbra system ace 68 reperfusion catheter (ace 68) and attempted to advance a penumbra system 3max reperfusion catheter (3maxc) through the ace68; however, the 3maxc broke where its shaft tapers from 4.7 to 3.8f.The 3maxc broke prior to use and therefore, was not used in the procedure.The procedure was completed using a new 3maxc, the same non-penumbra bleedback control valve and the same ace68.
