Medtronic

(MDT) - Get Report

has acquired Image-Guided Neurologics, a maker of products used during brain surgery.

Image-Guided's product line will strengthen Medtronic's "leadership position in deep brain stimulation (DBS) by offering instruments that simplify the procedure for surgeons and improve patient comfort during surgery," Medtronic said in a press release Tuesday.

The financial terms weren't disclosed.

When Medtronic's Activa neurostimulation system is being implanted, a metal frame is used to guide leads connecting the device to specific areas of the brain, limiting a patient's ability to move for several hours. The Image-Guided NexFrame is a more comfortable frame, is less stressful on the neck and allows the patient to move and change positions during surgery, Medtronic said.

According to the company, more than 30,000 patients have received Activa therapy to date, and Medtronic is exploring deep-brain stimulation to treat neurological disorders such as epilepsy, obsessive-compulsive disorder and depression.

Medtronic shares slipped 53 cents to $55.90 in recent trading.
