A gene therapy based on an enhanced lipid nanoparticle (LNP) loaded with vascular endothelial growth factor (VEGF) mRNA could be developed for the treatment of preeclampsia, according to a study in mice in which it alleviated maternal hypertension until the end of gestation and improved fetal health. Preeclampsia is a disease that affects 3% to 5% of pregnant women, who suffer from hypertension and proteinuria, elevated levels of protein in the urine, during pregnancy.

Heartbeam Inc. received U.S. FDA 510(K) clearance for its portable, non-invasive electrocardiogram system that enables on-the-go recording of heart signals. The cable-free, credit card-sized device uses five electrodes to capture signals from three directions and can be used whenever a patient feels symptoms, overcoming the challenge of identifying intermittent arrhythmias, which are often not experienced during scheduled appointments, without requiring patients to wear a device continuously.

Lanua Medical Ltd. raised €6 million (US$6.3 million) in seed funding for its Encore device, which is designed to enhance embolization procedures. The funds will be used to accelerate the development of the technology as well as expand operations into the U.S. The funding round was co-led by Elkstone and Atlantic Bridge, with participation from Enterprise Ireland and Furthr VC.

Capstan Medical Inc. closed an oversubscribed series C fundraising round that brought in $110 million for the structural heart-focused company. Capstan aims to combine valve implants, advanced catheter technology and a robotic platform to facilitate expanded minimally invasive treatment options for patients with heart valve disease.

Stereotaxis Inc. and Chinese partner Shanghai Microport EP Medtech Co. Ltd. gained the National Medical Products Administration’s approval of its Magbot magnetic navigation ablation catheter Dec. 9 for use with Stereotaxis’ robotic ablation system to treat drug-resistant cardiac arrhythmias in China.

Administrators at the U.S. Medicare program have proposed to cover the Cardiomems remote monitoring device for heart failure, but cardiologists are averse to several of the conditions spelled out in the draft coverage memo, including what they see as a somewhat futile demand for a comparator arm in the proposed coverage study.

At its investor day conference, Edwards Lifesciences Corp. prognosticated that an expanded indication in transcatheter aortic valve replacement and rapid growth in its newer mitral and tricuspid heart valve technologies will accelerate total company sales in 2026 and beyond.

The force is with Field Medical Inc. as it celebrates the U.S. FDA’s decisions to grant breakthrough device designation (BDD) to its Fieldforce ablation system and to accept it into the agency’s Total Product Life Cycle Advisory Program pilot. Field Medical designed the Fieldforce pulsed field ablation catheter specifically to treat ventricular tachycardia. The BDD applies to its use in monomorphic scar-related VT.

Meril Life Sciences Pvt Ltd. recently launched its next generation transcatheter heart valve (THV), the Myval Octapro THV, which it says allows for better operator control for precise positioning and improved predictability in implantation. The new valve comes however, as the company battles with Edwards Lifesciences Corp. in a European court over patent infringement of its technology.

Although there is a clear clinical need for transcatheter mitral valve replacement technologies, a number of challenges must be overcome before they can safely be used to treat patients with mitral regurgitation. Nevertheless, two new devices could enter the European market next year, Edwards Lifesciences Corp.’s Sapien M3 and Highlife Medical SAS’s Highlife TMVR device.
