VoluMetrix

VoluMetrix is a private Nashville-based medical device company developing non-invasive patient monitoring technologies based on proprietary venous waveform analysis. Its core platform, NIVA (Non-Invasive Venous waveform Analysis), is designed to estimate hemodynamic status and congestion using a wrist-worn sensor and signal-analysis software. The company’s lead product, NIVA|HF, is an investigational device for heart failure monitoring that has received FDA Breakthrough Device designation. VoluMetrix appears focused on translating its waveform platform from hospital to home monitoring for patients with heart failure and related fluid-management needs. The business sits at the intersection of medical devices, remote monitoring, and digital health rather than traditional therapeutics.
