Adagio Medical receives CE mark for iCLAS ablation system

Adagio Medical has received CE mark approval for its ultra-low temperature intelligent Continuous Lesion Ablation System (iCLAS) for the endocardial treatment of paroxysmal (PAF) and persistent (PsAF) atrial fibrillation and atrial flutter.

“More than half of all atrial fibrillation (AF) patients are diagnosed with PsAF. There is a strong demand to treat this patient group with endocardial, continuous, transmural lesion sets with results similar to what has been shown with the surgical Maze procedure. Using a single iCLAS catheter, the procedure can be completed in less than one hour,” says Olav Bergheim, CEO of Adagio Medical.

The 8.5Fr iCLAS catheter combines ablation and diagnostic capabilities, thereby requiring only a single transseptal puncture Adagio Medical said in a press release. The iCLAS procedure can be done utilising an anatomical approach which eliminates the need for electromagnetic mapping. The ability to exchange stylets, without removing the catheter, allows for unlimited shapes and sizes of both the ablation and diagnostic sections of the catheter.

“The multicentre European CryoCure II clinical study has shown that we can perform pulmonary vein isolation (PVI) in combination with other ablations in both atria (e.g. posterior wall box and cavo tricuspid isthmus isolation), even in the most difficult to treat PsAF patients. The uniquely versatile delivery system enables the ablation procedure to be performed with a single catheter. Ablations beyond PVI only add a few minutes to the total procedure time,” said Tom De Potter, associate director, Cardiovascular Center OLV Hospital (Aalst, Belgium). “Similar to what was presented at the 2019 Heart Rhythm Society meeting, the CryoCure II data continues to show PsAF outcomes with 85% freedom from atrial arrythmias at 12 months.”

Adagio Medical is preparing for a limited European commercial launch of the iCLAS in early summer of this year. “With this CE mark approval, we are excited to offer this novel treatment to the large PsAF patient population,” commented Michael Heuer, general manager, Europe.

Adagio Medical is conducting a prospective, single-arm, controlled IDE study in 20 centres in the USA, Western Europe, and Canada. The study is designed to demonstrate the safety and efficacy of iCLAS for the treatment of PsAF.
