Indications
The Merlin™ PCS Model 3650 programmer is indicated for use for patients with
bradyarrhythmias, tachyarrhythmias or heart failure undergoing implantation, lead revision,
explant or device follow-up of a cardiac monitor, pacemaker, implantable cardioverter defibrillator,
or cardiac resynchronization therapy system.
Intended Use
The St. Jude Medical Merlin™ PCS Model 3650 is a portable, dedicated system designed to
interrogate, program, display data from, and test St. Jude Medical implantable devices during
implant and follow up. At time of implant, it is intended to assess the pacing and sensing
performance of the lead after it is connected to the pulse generator.
The Telemetry Wand Model 3630 is intended to provide inductive communication between the
programmer and the pulse generator during a programming session.
The Merlin PCS ECG function when using the ECG cable Models 3617, 3626 and EX3001 is
intended to display the patient electrocardiogram and used to support activities related to
implanting, programming, and monitoring St. Jude Medical implantable pulse generators.
The Merlin Antenna Model 3638 is a dedicated radio antenna accessory intended to enable
wireless radio frequency (RF) communication between the Merlin PCS and St. Jude Medical
implantable pulse generators with RF communication capability during a programming session.
The Merlin PSA Model EX3100 and the PSA Patient Cable Model 3150 are pacing analyzer
systems intended for use with the Merlin PCS to evaluate implanted leads for integrity, and for
pacing and sensing performance during surgical procedures related to the implanted system.
The Magnet Model 3630M is intended to support inductive communication with specific pulse
generators or to enable device-specific magnet settings, such as high voltage therapy inhibition or
asynchronous mode activation, when placed over an implanted pulse generator.
Contraindications
There are no contraindications to the use of the St. Jude Medical Merlin™ PCS Model 3650 to
interrogate, program, display data from, and test implantable devices during implant and follow
