Event Description

It was reported that a patient underwent an ablation procedure with a lasso® nav eco variable catheter for which biosense webster¿s product analysis lab has identified electrode damage with sharp edges.It was initially reported by the customer that during the procedure, the product showed no malfunction, however, after the successful procedure, the physician checked the lasso® nav eco variable catheter and noticed a light kinking between the electrode.There were no patient consequences.On 7/5/2019, additional information was received from the customer indicating the customer did not observe any sharp rings, no exposed wires, no difficulty inserting or removing the catheter and the sheath used was an abbott agilis 11.5 french.The customer¿s reported issue was assessed as not reportable since the potential that it could cause or contribute to a death or serious injury, or other significant adverse event, is remote.On 8/20/2019, the complaint product was returned to biosense webster inc.¿s (bwi) product analysis lab (pal) for evaluation.Initial visual inspection found the tip of loop is slightly bent.This was not considered to be mdr reportable.On 9/10/2019, during a second visual inspection, the tip was found slightly bent.Ring 1 was found damaged and sharp-edges can be observed as well as the polyurethane (pu) was detached.These findings were reviewed and assessed the damaged and sharp edges as mdr reportable malfunction.This event was originally considered non-reportable, however, bwi became aware of a reportable malfunction through visual analysis on 9/10/2019 and has reassessed this complaint as reportable.
