Neurostimulation

Electronic medical devices require a high level of research and engineering expertise to develop new devices and techniques for electronic device manufacturing. In addition, neurological treatment devices used in neurological treatments must meet superior biocompatibility and quality standards. Quasar’s specialty in micro-assembly and our extensive experience with designing new and improved products, as well as mass-producing them via novel techniques is unmatched.

Applications for Neurostimulation

  • Chronic pain
  • Paralysis
  • Neural prosthetics
  • Neurological disorders such as Alzheimer’s disease, Parkinson’s, epilepsy, and sleep apnea 

Electronics are now the norm in medical devices including pacemakers, battery-operated mechanical pumps, etc. Breakthrough innovations have paved the way for the use of micro-electronic devices capable of providing life-saving treatment for many who suffer from irreversible chronic conditions. Neurostimulation (NS) involves both invasive and minimally invasive methods of providing electrical stimulation to target locations around the brain and spinal cord.

Pain-sensing can be redirected using electrical impulses that impede the pain signal as it travels to the brain, thus misleading the brain into not sensing the pain caused by various chronic disease conditions.

Other neurological conditions such as depression, epilepsy, Parkinson’s, and Alzheimer’s are the result of misfiring neurons and malfunctioning neurological tissues. Interventional therapy using neurostimulation systems are increasingly used to alleviate symptoms that are otherwise unresponsive to other treatments.

Non-invasive techniques include:

Transcranial electrical stimulation: This uses either transcranial direct current stimulation (tDCS) or transcranial current stimulation (tACS) through a device that can be worn outside or subcutaneously, i.e., under the skin in the abdomen or any other location. The device is made from biomedical grade materials, contains a battery, and has one or more insulated leads that deliver the electrical stimulation to the desired location, such as the epidural space near the spine or brain. Placing the leads in precise locations is critical, especially when employing tDCS devices.

Transcranial magnetic stimulation (TMS): These wearable devices deliver high-intensity magnetic pulses that produce neuromodulatory effects on the brain. Magnetic coils are used to generate magnetic pulses. By varying the frequency of the pulses, the level of excitability in the brain can be modulated. Conditions such as chronic pain, mobility-related conditions, epilepsy, and stroke can be treated with such devices.

Low intensity focused ultrasound: This delivers ultrasound to the brain to treat movement disorders. While the device has received the CE mark, FDA approval is still pending.

In order to manufacture electrodes to be implanted subcutaneously within a patient’s body, it is essential to employ biomedical grade materials in the construction of the neurostimulation system. Quasar offers the biocompatibility and other testing expertise necessary for developing improved materials for use as neurostimulator components, including the body of the device to be implanted subcutaneously, lead sheaths, leads, electrodes, and magnetic coils.

One of Quasar’s many strengths is its research and design capabilities for new process development (NPD) to introduce improved devices with superior materials and specifications. Quasar draws up designs for manufacture (DFM), depicted via a clear process flow diagram (PFD), so you can effectively evaluate the assembly stages and critical points, as well as the testing processes employed. Our expert evaluators work to eliminate waste, remove barriers to production, and ensure highly streamlined production, testing, and packaging processes. Quasar’s extensive experience and research capabilities make new product introduction (NPI) possible. Our full turnkey (FTK) solutions ensure cost-efficiency, faster time to market, and that comprehensive compliance regulations are met and maintained to the highest standards.
