His work focuses on enhancing the delivery of therapeutic agents via suture materials.

Latest Patents

Chunlei Zhu holds a patent for "Surgical suture materials with porous sheaths for drug delivery." This invention discloses surgical suture materials designed to facilitate the sustained delivery of releasable components. The suture materials are processed to create a layer of pores extending inward from the outer surface. Specifically, the sutures are swollen in a calcium-ion containing solution and then freeze-dried to create pores that can be filled with a releasable component for delivery to tissue. One embodiment features a suture with an outer sheath that defines a lumen, through which elongated filaments extend. This design allows for efficient loading of a releasable component into the lumen, ensuring sustained delivery while maintaining mechanical integrity due to coordination bonds formed between calcium ions and polymer chains.
