Medical device maker NuVasive Inc. said Wednesday it expects to report 2011 revenue of about $540 million, which falls at the top end of its previously issued guidance for last year.
The San Diego company had forecast revenue of between $538 million and $540 million. Analysts surveyed by FactSet expect, on average, $538.7 million in revenue.
NuVasive said results included about $8.5 million from its acquisition of Impulse Monitoring Inc., which closed Oct. 7.
Impulse Monitoring provides neurophysiologists to assist spine surgeons in nerve monitoring. NuVasive has said the $80-million acquisition will help increase the penetration of its NeuroVision system, which identifies nerves during spinal fusion surgeries.
NuVasive develops surgical products for spine procedures. It will announce complete results for its fourth quarter and the full year, as well as 2012 guidance, on Feb. 22 after the market closes.
Company shares climbed 3.7 percent, or 45 cents, to $12.75 in morning trading Wednesday while the Nasdaq exchange fell slightly.
