Recalls

8 recalls · FDA

    • Terminated Z-2848-2020 FDA Class II initiated 14 Jul 2020

    Hardware error- Hot Plugging feature could cause an electrical malfunction on the main control D80 (below revision 04 installed) of the generator which is part of the main unit (c-arm) and cause permanent loss of imaging functionality.

    • Terminated Z-0782-2020 FDA Class II initiated 25 Nov 2019

    During a routine inspection of a system, a crack on the C-arm holder was discovered. In the event the C-arm holder has a crack, the stability of the C-arm may be compromised and could lead to deformations of the C-arm. In very unlikely cases, an extreme impact to the C-arm such as heavy collision with a wall or table, may lead to a detachment of the C-arm and could potentially result in injury to patients and staff.

    • Terminated Z-1953-2019 FDA Class II initiated 20 Jun 2019

    DAP chamber may be missing an insulating foil

    • Terminated Z-1298-2019 FDA Class II initiated 18 Mar 2019

    Continuous operation at very high tube output may result in increased wear of the radiation emitting components. This may occur when tube voltages of 125 kV are used for a long period, e.g. 30 minutes or more of continuous use. As a result, risk of premature failure of the Monoblock and loss of imaging X-rays.
