The 5f pro-picc was returned for evaluation in three pieces: the picc hub/extension assembly with approximately 2.5 cm of lumen attached and two additional pieces of lumen, one 11.3 cm in length and the other 17 cm long.The guidewire was not returned.The hub of the picc appears to be cut beginning approximately 1 cm proximal to the tip of the hub, extending to the end of the hub and down the lumen to the 0 cm mark.When the device was turned over another cut could be seen just below the 0 cm mark to the 1 cm mark.Just below that cut another cut can be seen going across the lumen with a tear from that cut to the tip of the lumen.The longer of the lumen pieces has smooth ends but the shorter of the returned lumens has one smooth end and one jagged end.The condition of the returned device suggests extreme force was applied to the guidewire when withdrawing it from the catheter.A supplier corrective action request was issued to the contract manufacturer.The contract manufacturer conducted an investigation and evaluation of the returned device.The sample was received on 3 sectioned parts; however, the involved guide wire was not returned.The sectioned catheter shows a rupture from the end of the molded hub to the lumen, the rupture is approximately 1.30" long.The catheter lumen sections were functionally inspected using a 0.018" guidewire on both lumen sides.The guidewire passed freely without any resistance.The catheter hub was visually inspected and no kinks, holes, gaps, or surface voids on the molded hub or junctions with lumen and extensions and no flash was found.The catheter hub was cross sectioned; no internal voids and no extensions insertion or lumen insertion issues were found.Prior to preforming the hub cross section, a 0.018" guidewire was used on both molded hub sides, and it passed freely without any resistance.No defects related to the extrusion lumen process or molding hub process were found.A review of the manufacture records for the lot number reported revealed the device was manufactured and inspected according to specification with no non-conformances or abnormalities.The manufacture process includes a 100% guidewire test in which a.018" guidewire is inserted from the tip of both lumens.The guidewire test is performed after the mold hub operation.If the molded catheter has an occlusion or guidewire resistance transition for any lumen, the guidewire operation is able to detect it.The circumstances that led to this complaint condition cannot be determined but is not likely manufacture related.The instructions for use (ifu) includes the following cautions and warnings: do not advance the guidewire or catheter if unusual resistance is encountered.Do not insert or withdraw the guidewire forcibly from any component.The wire may break or unravel.If the guidewire becomes damaged, the introducer needle or sheath/dilator and guidewire must be removed together.Caution: guidewire is hydrophilic.Hydrate prior to use.
