Medtronic plc has kicked off two clinical trials of its Evolut transcatheter aortic valve replacement (TAVR) system. One study will pit the self-expanding Evolut Pro and Pro+TAVR systems against Edwards Lifesciences Corp.’s balloon-expandable Sapien 3 and Sapien 3 Ultra transcatheter heart valves in small annulus patients.

Two teams of researchers have developed miniature models of the human heart that beat and function like the full-size organ. The team from Michigan State University (MSU) and Washington University in St. Louis developed a human heart organoid (hHO) that recapitulates embryonic heart development, providing an unmatched view into congenital heart defects. The organoid created by the researchers at the Medical University of South Carolina (MUSC) and Clemson University mimics the tissue dysfunction that occurs following a heart attack.

San Carlos, Calif.-based Galaxy Medical Inc., which has developed pulsed electric field (PEF) technology for the treatment of cardiac arrhythmias, revealed the first treatments in the ECLIPSE-AF study, which is evaluating the Centauri system. The trial will assess the safety and efficacy of the Centauri as the company looks forward to obtaining a CE mark.

Biosense Webster Inc. reported U.S. FDA approval of its Thermocool Smarttouch SF ablation catheter for the treatment of patients with persistent atrial fibrillation (persistent AF). This follows results of the prospective, multicenter Precept study, which showed the catheter to be safe and effective for 80% of patients over 15 months of ablation therapy with clinically meaningful improvement in quality of life.

PERTH, Australia – Astrazeneca plc is leasing 175 Sozo devices from Impedimed Ltd. and plans to put them in 20 countries to run phase II trials for a combination drug that looks at fluid imbalance in the human body in patients with heart failure (HF) and chronic kidney disease.

Medtronic plc’s winning streak continued this week with the announcement that the U.S. FDA had given its nod for new one-month of dual-antiplatelet therapy (DAPT) labeling with an expanded indication for high bleeding risk (HBR) patients implanted with the Resolute Onyx drug-eluting stent (DES). The approval is based on results from the Onyx ONE Clear Study that evaluated about 1,500 complex HBR patients on one-month DAPT treated with Resolute Onyx.

Alucent Biomedical Inc., which is developing a restorative therapy for peripheral artery disease (PAD), completed a $35 million series B financing led by a multinational strategic investor. The funds will be used to complete clinical studies of the Alucent Natural Vascular Scaffolding (AlucentNVS) vessel restoration system with photoactivated linking, the company’s first product.

Sentiar Inc. received U.S. FDA clearance for its holographic guidance system, known as Commandep, for use in cardiac ablation procedures. The system allows electrophysiologists (EPs) to visualize 3D electroanatomic models in real-time, using augmented reality (AR), to seamlessly navigate invasive procedures. “The Commandep is intended for use as a medical imaging system that allows the review, analysis, communication and media interchange of multidimensional digital images,” Berk Tas, Sentiar’s CEO, told BioWorld.
