AN INNOVATIVE SOLUTION DESIGNED TO PROVIDE
A MORE GENTLE WAY TO RESTORE NORMAL HEART RHYTHM

Cardialen is developing low-energy implantable defibrillation therapy designed to more gently restore the heart to a normal rhythm.

The innovative therapy is called unpinning termination (UPT) therapy and it's designed to deliver a sequence of low-energy electrical pulses timed to disrupt the ongoing arrhythmic cardiac cycle.

Existing high-energy defibrillators can cause negative side-effects for the patient, including tissue damage and scarring. And while attempts to treat AF with current implantable defibrillators has been successful, the painful shocks are nearly intolerable for most patients.1 Recent studies indicate high-energy VF therapies may lead to increased mortality compared to patients receiving fewer shocks or a low-energy therapy.2,3 UPT therapy is being developed to treat fibrillations while reducing these negative effects.

Early human feasibility study data suggests that it may successfully treat heart rhythm disorders with substantially lower-energy therapy than is needed by existing defibrillators.4,5

Clinical Testing:

Ultimately, Cardialen's UPT therapy is designed to provide a more gentle, low-energy alternative to restoring normal heart rhythm to those affected by tachyarrhythmias.
