Recalls

18 recalls · FDA

    • Terminated Z-0977-2020 FDA Class II initiated 4 Jan 2019

    The wire guide may be incorrectly loaded into the wire guide holder, leading to the stiff tip of the wire guide being introduced into the patient instead of the flexible tip.

    • Terminated Z-0852-2011 FDA Unclassified (pre-2012) initiated 18 Oct 2010

    The firm received a customer complaint that a box labeled as Universa Firm Stents but the box actually contained Universa Soft Stents. The inner product label is correct but the outer box is wrong.

    • Terminated Z-0980-2009 FDA Unclassified (pre-2012) initiated 10 Nov 2008

    "Soft" stents were placed in "firm" stent outer boxes. The soft stent is only to be left in the patient for 6 months, but the firm stent can be left in the patient for 12 months, so this error could result in the stent being left in the patient for longer than indicated for the device.
