In December of 1995 FDA approved the Res-Q ACD. This was Intermedics’ first implantable defibrillator. The abdominal-implant device was a relatively late-comer, and large for the time (230 g), but it did offer the highest energy output (40 Joules). Another unique feature of the ResQ device was that it provided a connectorized sterile package which allowed complete pre-implant testing, thereby reducing the need for additional equipment.
