Temporary cardiac pacing is often required for hospitalized cardiac patients, particularly for increasingly common transcatheter aortic valve replacement (TAVR) procedures. Startup Atacor Medical Inc. has raised a $25 million series B round to back its development of a novel extracardiac temporary pacing system. Intriguingly led by an undisclosed corporate partner, the financing is slated to get the company through a U.S. and European pivotal trial, as well as regulatory review in those regions. The San Clemente, Calif.-based startup also aims to continue developing interim and permanent iterations of its system.
