Manufacturer Reason
for Recall
An issue exists with a specific subset of Sigma series pacemakers that may fail due to separation of interconnect wires from the hybrid circuit. This failure mechanism may present clinically as loss of rate response, premature battery depletion, intermittent or total loss of telemetry, or not output. There have been no reported patient injuries or deaths due to this issue.
