FDA Device

e.cam Gamma Camera, an emission computed tomography system. It is intended to detect or image the distribution of radionuclides in the body or organ, using the following techniques: planar imaging, whole body imaging, tomographic imaging for isotopes with energies up to 588keV.

Hazard

Potential failure mode related to the radial brake, where the detector was able to drift, led to a re-design of the brake redundancy circuit. The redesigned Brake Redundancy Circuit will force even a defective brake to engage in the unpowered state by applying a reverse charge to the brake and ensuring the brake has demagnetized.

What You Should Do

Remedy

The firm, Siemens, sent out an undated "CUSTOMER SAFETY ADVISORY NOTICE" on 04 April 2015 to its consignees informing them of the e.com system safety update. The notice described the product, problem and actions to be taken. The notice stated the following: In order for an injury to occur, the following series of events must be present; 1. The detector configuration angle must be 180 degrees. 2. The detector with the failed brake circuit must be above the patient. 3. The detector with the faulty brake circuit must be under power (in motion). 4. System power must cycle within a very short time period, preventing the brake circuit from charging. The customers were instructed to continue to use their e.com system and to ensure the safety advisory is placed in the systems instructions for use and to observe patients while system is in use. If they experience difficulty or failure while performing the daily touch pad test, they are advised to discontinue use and contact their local representative. If unintended movement is detected they are advised to remove the patient and discontinue using the system and contact their local service representative.
