Device evaluation summary: the powercross dilatation catheter was received for evaluation.The powercross was received with the balloon chamber in a pre-inflation profile, (e.G.Tightly wrapped and winged).Sanguine residue was noted on the exterior of the balloon chamber.The returned state of the dilatation catheter was consistent with the initial reported event.The inner guide wire lumen within the balloon chamber was visually examined.No proximal marker band was noted in the proximal area of the balloon chamber.Visual examination confirmed the initial reported event.The distal marker band was present.The balloon chamber of the powercross was rinsed with water to remove the sanguine residue from the exterior of the balloon to aid visual inspection.The overall length of the dilatation catheter was examined.Several minor kinks were noted in the catheter.The kinks are located approximately 55.0cm, 105.7cm, 136.5cm and 139.5cm distal of the distal tip of the y-manifold strain relief.The kinks may have formed during the procedure, (e.G.During insertion or removal from the patient), or post-procedure given how the device was packaged for return.A 20cc water filled syringe was attached to the proximal hub luer lock on the y-manifold.The inner guide wire lumen was flushed: a clear steady stream of fluid was observed exiting the distal tip of the dilatation catheter.A 0.018¿ guide wire was able to be loaded through the distal tip of the dilatation catheter with ease.A 10cc water filled syringe was attached to the inflation lumen luer lock on the y-manifold.A vacuum could be pulled and maintained; indicated no leak in the inflatio n lumen.The balloon chamber was inflated: no leaks were noted.The inner guide wire lumen within the balloon chamber was visually examined: no proximal marker band was noted.A vacuum was pulled and the balloon chamber deflated with ease.
