NuVasive has accomplished a definitive agreement to acquire Impulse Monitoring, an intra-operative monitoring (IOM) provider in the United States for $80m, comprised of $40m in cash and $40m in stock.

The acquisition will complement NuVasive’s existing nerve monitoring system, NeuroVision, which is designed for discreet and directional nerve avoidance and detection, making lateral access to the spine during the XLIF procedure safer and reproducible.

The acquisition is expected to close this month, subject to customary closing conditions and government approvals.

NuVasive anticipates that Impulse Monitoring will contribute more than $8m to Q4, 2011 revenue and is growing at an annual run rate approaching $40m.

NuVasive chairman and CEO Alex Lukianov said the transaction will further differentiate NuVasive’s surgical solutions and add value to hospitals, surgeons and patients by procedurally integrating products and services.

Impulse Monitoring CEO Gene Cattarina said together they will help expand their services to not only meet the needs of hospitals and surgeons, but also provide high quality patient care.
