Fine medical wire helps to change lives with deep brain stimulation
EXERA® fine medical wire from Sandvik is specifically developed to transmit, sense or stimulate signals within the body. Conditions such as Parkinson’s, epilepsy, essential tremors and obsessive-compulsive disorder (OCD) can be significantly improved with a neurostimulator.
Similar to a pacemaker, the amount of stimulation is controlled by a device situated under the skin, usually located in the upper chest. Medical wire connects this device to electrodes that are implanted in the brain, acting as the stimulator. When it comes to stimulation therapy, medical wire plays an important role in providing electrical energy to precise parts of the body, such as the brain, spine or wherever natural signals have been disrupted.
Much like any medical device that is implanted internally, fine medical wire for stimulation therapy must be lubricious and malleable enough to be precisely directed in the body so that the right area is targeted for stimulation.
There are typically multiple wires used in a very small space for the stimulation
“There are typically multiple wires used in a very small space for the stimulation”, explains Gary Davies, manager at Sandvik Materials Technology’s business unit for medical wire manufacturing. “These wires usually have a dielectric coating, so they don’t short to each other and disrupt the signal or electrical energy that is being sent to the nerve to correct the problem. This has to be done in a precise and reliable way as we don’t want to introduce stimulation that will not have the desired effect.”
