Advanced Medical Cable Assemblies for Neuromodulation


Novara Technologies, a pioneering manufacturer of medical cable assemblies, has recently partnered with a leading customer in the field of Neuromonitoring and Neuromodulation to design and manufacture an innovative cable assembly solution for precise and reliable neural signal monitoring.

What is Neuromodulation?

A transformative technology that directly influences nerves, holds immense potential in the field of healthcare. With its broad therapeutic scope and continuous advancements in biotechnology, neuromodulation is emerging as a major growth industry with the potential to revolutionize the treatment of various diseases and symptoms.

The Role of Medical Cable Assemblies in Neuromodulation

Medical cable assemblies play a vital role in enabling effective neuromodulation therapies. These specialized cable assemblies are designed to facilitate the precise and reliable transmission of electrical signals to the target areas. They serve as the crucial link between the neuromodulation devices and the nerves, ensuring accurate and controlled stimulation or modulation.

Specific Advantages of Medical Cable Assemblies in Neuromodulation

  1. Precise Signal Delivery: Our cable assemblies are engineered to deliver electrical signals with exceptional precision, allowing for targeted neuromodulation. The design of these assemblies minimizes signal loss and interference, ensuring optimal signal integrity for effective treatment outcomes.
  2. Biocompatibility and Safety: Given the potential for direct interaction with nerves and tissues, biocompatibility is of the utmost importance. These cable assemblies are carefully manufactured using biocompatible materials that are safe for use within the human body. These materials undergo rigorous ISO10993 testing to ensure that they do not cause irritation, toxicity or adverse reactions and certified for use in medical device applications.
  3. Customization for Targeted Treatments: Medical cable assemblies can be customized to meet the specific needs of different neuromodulation therapies. Whether it’s deep brain stimulation (DBS), spinal cord stimulation (SCS) or peripheral nerve stimulation (PNS), cable assemblies can be tailored to accommodate the unique requirements of each treatment approach.
  4. Reliability and Durability: Neuromodulation therapies often involve long-term implantation of devices, making reliability and durability crucial factors. Our cable assemblies are designed to withstand the challenges of long-term use, ensuring consistent performance and reducing the need for frequent replacements or maintenance.

Case Study: Medical Cable Assembly in a Neuromonitoring Application

Let’s explore a specific application of a medical cable assembly used for IntraOperative Neurophysiological Monitoring (IONM) during brain tumor and epilepsy surgeries. In these procedures, a single-use medical device incorporates a specialized cable assembly as an essential component. This cable assembly assists in the continuous recording of the brain’s spontaneous electrical activity (ECoG) and somatosensory evoked potentials (SEPs). It also plays a crucial role in brain stimulation, aimed at eliciting motor evoked potentials (MEPs).

The customer had specific requirements that needed to be met to ensure optimal performance and patient safety.

Requirement 1: Ultra-flexibility and Small Diameter

Given the proximity of the cable assembly to the brain, it was crucial for it to have a small diameter and be ultra-flexible. This requirement aimed to minimize the risk of trauma during the surgical procedure and ensure patient comfort throughout the monitoring session. The medical cable assembly was designed with specially selected materials and construction techniques to achieve the desired flexibility whilst maintaining the necessary electrical integrity.

Requirement 2: Soldering of Extra Fine Wires to a PCB

The customer also required the capability to solder extra fine wires to a printed circuit board (PCB) that would be attached to their electrodes. This requirement was essential for establishing reliable electrical connections between the electrodes and the cable assembly. The medical cable assembly was designed with specific connectors and soldering techniques to ensure secure and durable connections between the fine wires and the bespoke PCB.

Requirement 3: Biocompatibility and Low Bioburden

Due to the proximity of the medical cable assembly to the brain and the extended duration of IONM monitoring, biocompatibility and low bioburden were of utmost importance. The materials used in the construction of the cable assembly were carefully selected to be biocompatible, ensuring compatibility with the patient’s body and minimizing the risk of adverse reactions. Moreover, the cable assembly was manufactured in a controlled, cleanroom environment to minimize bioburden and maintain the highest level of cleanliness.

By addressing these specific requirements, the medical cable assembly provided an optimal solution for the customer’s IONM application. It’s ultra-flexibility and small diameter reduced the risk of trauma and improved patient comfort. The soldering of extra fine wires to the PCB ensured secure and reliable electrical connections. Furthermore, the cable assembly’s biocompatibility and low bioburden guaranteed patient safety and minimized the potential for complications during the monitoring process.

This case study highlights the significance of customized medical cable assemblies in meeting the unique needs of neuromonitoring applications such as EEG. By collaborating with customers and understanding their specific requirements, Novara Technologies can develop tailored solutions that enhance the effectiveness and safety of these critical procedures.

Choosing the Right Medical Cable Assembly Manufacturer

Selecting the right cable assembly manufacturer and considering key factors is crucial when it comes to ensuring the quality and safety of medical cable assemblies. Here are the important considerations to keep in mind:

  1. Quality Certification: You should look for a cable assembly manufacturer that holds relevant quality certifications, such as ISO 13485. This certification ensures that the manufacturer is adhering to strict quality management systems specific to the medical device industry. It demonstrates our commitment to maintaining high standards and meeting regulatory requirements.
  2. Cleanroom Manufacturing: Choose a cable assembly manufacturer with a cleanroom facility suitable for all the necessary manufacturing processes involved in the production of medical cable assemblies. A cleanroom environment helps minimize bioburden, contaminants, and particulate matter during assembly, which is crucial for maintaining the cleanliness and integrity of the cables.
  3. Choice of Materials: The materials used in medical cable assemblies must be carefully selected to ensure biocompatibility, safety, and reliability. It is important to work with a manufacturer that uses materials that are specifically designed and are certified for medical use. These materials should be non-toxic and non-irritating to prevent any adverse reactions when in contact with the patient’s body.
  4. Experience and Expertise: Consider the manufacturer’s experience and expertise in producing medical cable assemblies for medical device applications. Look for a manufacturer with a track record of delivering high-quality products in this specialized field. Their knowledge and understanding of the specific requirements and challenges associated with these applications can contribute to the successful development and production of reliable cable assemblies.
