St. Jude Medical devices are unique because beyond having all the features that are useful in treating the typical patient, they have the extra features to help treat patients who are more challenging:
-
High output (36 J delivered/42 J stored energy) provides unsurpassed energy for defibrillation
-
DeFT Response™ technology - Many drugs have been shown to raise defibrillation thresholds to potentially unsafe levels.1 Our unique DeFT Response technology tools provide more clinically proven, non-invasive options for managing high DFTs.
-
SenseAbility™ technology – The SenseAbility feature with decay delay and threshold start, provides the flexibility to fine-tune sensing to individual patient needs and help eliminate oversensing of T waves, far-field R waves, fractionated QRS complexes, and other extraneous signals
-
Vibratory patient notifier – Exclusive vibratory patient notifier allows even patients with hearing problems to be alerted to a low battery, lead-related issues and more
-
DC Fibber™ induction – Our exclusive DC Fibber VF induction has a documented 95.5% success rate for inducing fibrillation on the first induction as compared with a 72.7% success rate for Shock-on-T2
-
AF Suppression™ algorithm (Atlas II+ HF only) – Our proprietary AF Suppression algorithm is clinically proven to suppress episodes of paroxysmal and persistent AF. Studies show a 25% decrease in symptomatic AF burden.3
- QuickOpt™ timing cycle optimization – IEGM-based AV/PV optimization allows optimized timing without the need for echo-guided optimization. QuickOpt timing provides quick and effective optimization for more patients at the push of a button.
-
V-V timing optimization – V-V timing optimization can help improve patient outcomes. Because not all patients respond to simultaneous biventricular pacing, programmable timing of right and left ventricular outputs helps to ensure appropriate therapy and may reduce the number of non-responders.4
Faster and easier follow-ups mean that clinics can use their time more efficiently. Three changes in our new generation products speed follow-up times:
-
Telemetry speed that is up to 5x faster than previous products, making the transfer of data to the programmer faster
-
Merlin™ Patient Care System has a faster processor, which means that data gets processed faster and prints faster
-
Software has been redesigned to a more intuitive format (including terminology and consolidation of screens)
Patients will have the comfort of knowing that their device is functioning properly with the unique SJM® patient notifier. New to the II family ICD line, the SJM patient notifier uses vibration to notify the patient of critical system changes like low battery and lead fractures. The intent is to help patients with hearing difficulties get the critical notification and to avoid false alarms due to confusion with environmental noises.
