Implantable medical devices—such as pacemakers, defibrillators, and drug delivery implants—require extreme reliability, biocompatibility, and long-term hermetic sealing. These devices are implanted inside the human body, where they must withstand bodily fluids, temperature changes, and mechanical stress for years. Any failure or leakage can have life-threatening consequences for patients. Traditional welding methods may introduce vibration that damages sensitive internal electronics (such as batteries and sensors), or produce welds that degrade over time, leading to device failure. DaokeDao laser welding is non-contact and vibration-free, protecting internal electronics during the assembly process. The low-thermal-impact process minimizes heat transfer to surrounding components, avoiding material degradation and ensuring biocompatibility. It provides long-term hermetic sealing (helium leak rate ≤1×10⁻⁹ mbar·L/s), preventing the intrusion of bodily fluids and protecting internal components from corrosion. The process uses biocompatible materials and avoids adhesives or solvents, meeting strict medical safety standards (such as ISO 10993 and FDA regulations). Our laser systems feature ultra-precise positioning accuracy and process control, ensuring consistent weld quality for implantable components. They help medical device manufacturers produce reliable, safe implants that improve patient outcomes.
