The returned catheter was measured from the hub using a ruler and measured ~135cm which is longer than the catheter mfg.Length (~132cm).The tip was visibly missing from the catheter with an unwound coil protruding from the distal end.The device was observed to have significant flattening of the catheter and elongation starting at ~20 cm from the distal end, however, there was no visible impact to the catheter coil spacing.Using a microscope, no visible liner was present, which denotes that the failure was within the ts 1 section or distal tip.Based on the reported complaint event intake that the detached hippo segment remained within the zoom rdl catheter, the compatibility between the devices had remained for some portion at the distal end of the rdl catheter when removal of the device had commenced.The physical evidence of the returned hippo catheter, with visual deformations, is consistent with the hippo catheter becoming stuck due to a kink in the rdl catheter that prevented the hippo catheter distal tip from passing through that kinked point.Lbs 00807 072 aspiration system ifu rev.D was reviewed.In the warning section: never advance or withdraw an intravascular device against resistance until the cause of the resistance is determined by fluoroscopy.Movement of the device against resistance could dislodge a clot, perforate a vessel wall, or damage the device.Torqueing the catheter excessively while kinked may damage the device, resulting in separation of the catheter shaft.Withdraw the entire device (the device, microcatheter, and guidewire) if the device is severely kinked.
