Recall of EMBLEM™ S-ICD Subcutaneous Electrode (Model 3501) with potential risk of electrode body fracture

A Dear Healthcare Professional Letter has been issued by Boston Scientific Asia Pacific Pte Ltd to update healthcare professionals of the recall of EMBLEM^™ S-ICD Subcutaneous Electrode (Model 3501), as a follow-up to an earlier notification in December 2020 about the potential risk of electrode body fracture distal to the proximal sense ring with this device. Since then, there has been no change in the potential for life-threatening harm and no patient deaths related to this issue. The root cause to this body fracture is associated with the adhesive backfilled notch at a location distal to the proximal sense ring. To address the issue, the enhanced version of the electrode has been designed to move the connection of the sense conductor, notch, and adhesive to a centered location entirely under the sense ring. Healthcare professionals are advised to return the remaining inventory of the affected/original electrodes to Boston Scientific once the enhanced version is available. Please refer to the letter for details.
