The NerveBridge SX-11 is a biodegradable electroactive conduit system developed by Zheng-Dao Bioelectric for repairing severed or severely damaged peripheral nerves in patients with traumatic limb injuries or augmentation-related nerve shear. The conduit itself is a 2–40cm tube constructed from a piezoelectric silk-fibroin matrix seeded with Schwann cell analogs — lab-grown support cells that guide regenerating axons across the gap site. A micro-embedded electrode array along the conduit's inner surface delivers pulsed low-frequency electrical stimulation autonomously, drawing power from the body's own bioelectric field through Zheng-Dao's proprietary ambient harvest circuitry, eliminating the need for external power sources or battery replacement.

The SX-11 represents the third major revision of Zheng-Dao's nerve conduit line, incorporating lessons from the SX-9's widely reported fibrotic encapsulation failures. The silk-fibroin matrix degrades cleanly over 8–12 months as the regenerating nerve matures, leaving no permanent foreign body. Critically, the SX-11 includes a wireless telemetry node that broadcasts nerve conduction velocity data to the attending physician's interface, allowing real-time monitoring of regeneration progress without invasive follow-up procedures. It is available in 23 standardized diameter configurations to match nerve gauges from fine digital branches to major peripheral trunks like the ulnar and sciatic.

The SX-11 occupies a peculiar market niche: it is primarily prescribed by Zheng-Dao-affiliated clinics as a prerequisite procedure before installing their higher-margin neural augmentation hardware, ensuring nerve pathways are intact and optimized for implant integration. Critics within the medical community note that this creates a financial incentive to recommend NerveBridge procedures even in cases where natural regeneration might suffice, effectively making the conduit a gatekeeping product for augmentation access.
