Approval Order Statement 
Approval for two corrective fixes to address a hardware issued that can leave the crt-d and icd systems listed above in a post-sense refractory state. For devices that are already implanted and/or already manufactured, changes will be made to the programmer software. During a patient follow-up visit, the programmer will interrogate the device and download firmware ram code to correct the anomalous condition if it occurs. For new devices, a modification has been made to the sio2 chip hardware to check the sense refractory state every two seconds and end it if appropriate.
