SQ-RX Model 1010 Pulse Generator – used with Boston Scientific S-ICDs

Hazard alert – potential battery issue

8 November 2018

Consumers and health professionals are advised that Boston Scientific, in consultation with the TGA, has issued a hazard alert regarding its SQ-RX Model 1010 Pulse Generator, which is used in certain first-generation Subcutaneous Implantable Cardioverter Defibrillator (S-ICD) systems.

S-ICDs are implantable medical devices that use small electrical impulses to treat abnormal heart rhythms.

It has been identified that there is potential for a shortened replacement interval after a Charge Time (CT)/Battery Depleted (BD) alert or after the battery status reaches Elective Replacement Indicator (ERI). Latent battery malfunctions can lead to accelerated battery depletion and the need to replace it sooner than expected.

Please note, the SQ-RX Model 1010 Pulse Generator is no longer manufactured or implanted. Additionally, this issue does not affect Boston Scientific’s Emblem MRI or Emblem S-ICD devices, as they use different pulse generators and are supported by the Latitude Remote Patient Management System.
