Imricor announces new developments in MR compatible ablation products


imricorImricor is developing a magnetic resonance (MR) compatible injection catheter and has announced a joint development agreement with MiRTLE Medical to integrate MiRTLE’s MR compatible 12-lead ECG system with Imricor’s Advantage-MR EP Recorder/Stimulator System. This integration, along with Imricor’s MR compatible catheters, will enable cardiac ablations for ventricular tachycardia and atrial fibrillation under real-time magnetic resonance imaging (MRI) guidance.

Imricor Medical Systems recently announced its contract for up to US$2.4 million from the National Heart, Lung, and Blood Institute of the National Institutes of Health (NIH) to develop an MR compatible injection catheter for MRI-guided procedures. The ten month contract which has a two-year option period will support the continued advancement of real-time MRI guided interventions for the treatment of cardiac arrhythmias.

Fast-track funding for the MR compatible injection catheter is awarded in two phases. The final objective of the contract is to deliver clinical grade catheters and support an IDE submission for a US feasibility study. The addition of an injection catheter to Imricor’s existing MR-compatible devices, which include the Vision-MR RF Ablation Catheter and Advantage-MR EP Recorder/Stimulator System, will expand the available treatment options for MRI-guided cardiac interventions.

The use of MRI to guide cardiac ablations offers physicians significant advantages over traditional x-ray-guided procedures. Unlike x-ray imaging, MRI allows physicians to visualise soft tissue structures during the procedure. This allows physicians to modify the therapy protocol to address each patient’s unique cardiac structure and substrate and provides valuable intraprocedural lesion visualisation. Ablations guided by real-time MRI allows physicians to assess lesion formation to identify inadequate or incomplete ablation lines. These advantages have the potential to reduce the rate of arrhythmia recurrence following ablation and provide safer and faster procedures in an environment that is free of ionising radiation.

Earlier this year, Imricor also announced a partnership with Siemens Healthineers to develop an integrated system that combines real-time MRI scans with 3D-guided cardiac ablation.
