Latest Patents

Kajii's latest patents include a method for the manufacture of a nerve regeneration-inducing tube. This method emphasizes the creation of a tube with excellent pressure resistance, shape recovery properties, anti-kink properties, film exfoliation resistance, resistance to invasion of outer tissues, and leakage resistance. The tubular body is constructed by weaving together fibers made from biodegradable polymer. The outer surface of this tubular body is coated multiple times with a collagen solution, which is crucial for its functionality. The viscosity of the collagen solution applied to the outer surface ranges from 2 to 800 cps, with subsequent applications having a higher viscosity.

Another notable patent is the nerve regeneration-inducing tube itself, which is designed to promote cell growth and withstand pressure. This tube features a collagen solution applied to the outer surface of a tubular body woven with ultrafine fibers made from biodegradable and bioabsorbable polymer. The inner area of the tubular body is filled with collagen, and the degradation speed of the tube is adjusted to suit the connection of nerve gaps exceeding 40 mm. This innovative design includes collagen coated on the outer surface of a tubular body woven with fiber bundles, enhancing its effectiveness in nerve regeneration.
