A Packaged Solution to the Problems of Testing Arrhythmia Control Devices at Implant

A composite implantable arrhythmia control device (ACD) implements the functions of a bradycardia pacemaker, an antitachycardia pacemaker, a cardioverter, and a defibrillator in an integrated fashion. Given this broad spectrum of functionality, the implant testing for these devices can become a formidable endeavor requiring a large ensemble of expensive, complex support equipment, and a significant amount of time. However, if this procedure is not carried out correctly, the device might later fail to defibrillate. This article presents a unique packaging system for an ACD that allows the device to be used while it is still in its sterile package. The device may then be used during implant testing as the defibrillation test unit. This collapses the amount of support equipment that is required to just the ACD, its programmer, and an optional switch box. By providing additional support specifically for implant testing through the ACD programmer, implant testing may be reduced to a quick, easy-to-manage procedure. Since the device used during implant testing is the same device that will be implanted, this packaging system offers the further advantage that the physician can be confident that, once implanted, the ACD will function correctly.
