CARDIOVERTER
DEFIBRILLATORS
Designed to continuously monitor patients’ heart rhythm
and detect irregular heartbeats, implantable cardioverter
defibrillators (ICDs) deliver electrical signals and controlled shocks
in order to restore a normal heart rhythm when necessary.
GALLANT™ ICD SOLUTIONS
Gallant™ single and dual chamber ICDs feature a 40 Joules (J) maximum shock, Bluetooth® connectivity, and improved algorithms to achieve fast and effective therapy optimization for your patients.1,2
Timing is everything when shocking a patient out of ventricular fibrillation (VF). Precision Shock Technology (PST) delivers the right energy within the right time for greater first-shock success.3-11 Any energy outside this response window is wasted.

GREATER FIRST-SHOCK SUCCESS3
Gallant™ ICD solutions harness smartphone connectivity with long-lasting therapy and features you can intuitively program to meet your patients’ changing needs.
- Reduce inappropriate therapy with features proven to increase detection capabilities and safety margins12,13
- Encourage greater patient engagement with app-based remote monitoring
- Deliver powerful, lasting therapy with a small, contoured design that is 1.5 Tesla (T) and 3T Magnetic Resonance (MR) Conditional*
1.5T AND 3T MAGNETIC RESONANCE IMAGING (MRI)-READY SOLUTIONS*
GREATER ENGAGEMENT
Gallant™ ICD solutions offer smartphone connectivity to encourage greater patient engagement.

ENABLES EARLIER INTERVENTION
by communicating clinically relevant events sooner
PAIRS WITH OUR SECURE myMERLINPULSE™ APP
to streamline communications with your patients, potentially reducing clinic burden and simplifying workflow
MAY SAVE YOU AND YOUR CLINIC TIME
by reducing unnecessary calls to the clinic
PATIENTS CAN USE THE myMERLINPULSE™ APP TO:
CHECK CONNECTIVITY STATUS
to ensure their device is being properly monitored
ACCESS DEVICE STATUS
to check battery status and device model
FIND SUPPORT RESOURCES
such as clinic information, technical support numbers and frequently asked questions (FAQs) site
SEND DATA MANUALLY
as instructed by a clinician
VIEW HISTORY
of scheduled data transmissions, connection issues and patient notifications
SECURED DATA AND INFORMATION
You don’t have to worry about the safety of patient information with Abbott. The myMerlinPulse™ app transmits device status and information to the Merlin.net™ Patient Care Network through a secure, encrypted connection.
Advanced security measures include:
- Encryption when data is at rest and in motion
- Code signed and authenticated in the device, the patient app and the programmer
- Two-way authentication of credentials, for device and user
