The hospital reported that during an endoscopic vein harvesting procedure when using vasoview hemopro 2 device to harvest the saphenous vein.After the dissection process was completed, the harvester began to use the hemopro 2 to ligate branches.During this time, it was noticed that the bisector was not sliding easily through the hemopro 2 cannula.The black coating only peeled back.It was therefore removed and inspected.It was immediately noticed that the black plastic coating near the jaws of the device had torn and peeled back.No pieces of the device were lost.No piece detached into the harvesting tunnel.However, it was felt that the product was no longer safe to use and it was therefore removed from the surgical field.There was a very slight procedural delay.Just the time it took to open up a new hemopro 2 kit and hand off the defective kit.Less than 3 minutes.The case was finished with no other complications.No injuries occurred due to the defect.
