AI Technical Summary

⚠Technical Problem

The implantation process of electrode leads in implantable medical devices is cumbersome due to the need for repeated actuation of electromechanical fasteners for establishing and maintaining electrical connections, which can lead to wear and tear, and complicates the verification of proper electrode placement.

⚗Method used

Incorporation of spring-loaded contact elements on the lead connector and/or connector socket to facilitate a temporary electrical connection without the need for electromechanical fasteners during implantation, allowing for easy connection and disconnection until a suitable implantation site is verified, followed by permanent fixation using electromechanical fasteners.

🎯Benefits of technology

Simplifies the implantation process by reducing the risk of connector wear and tear and facilitating efficient verification of electrode placement, ensuring reliable electrical connections without compromising mechanical stability.
