Varian Medical Systems Inc is recalling Varian Real-Time Position Management System (RPM), A Respiratory Gating System; Version 1.7.3, All M due to Erroneously Resetting: RPM System version 1.7.3, software failure can occur that affects the gated radiotherapy treatment when phase-based gating is u. Based on FDA medical device recall database.
Summary derived from FDA notice
Reason for Recall
As stated by FDA
Erroneously Resetting: RPM System version 1.7.3, software failure can occur that affects the gated radiotherapy treatment when phase-based gating is used. RPM 1.7 erroneously resets the phase-based gating thresholds to system default during the treatment session, if the user accesses the Session options during the treatment session. This can lead to difference between the planned and delivered
Recommended Action
Per FDA guidance
Varian sent an Urgent Medical Device Correction letter on September 26, 2007, to all its direct consignees, informing them that the RPM version 1.7 may reset the phase thresholds if Sessions options are accessed during treatment. A Service Representative will be scheduling a visit to user site to perform the modification requested to address the problem, when a corrected software version is available.
