Constructed from superior polyimide, the microcatheter showcases exceptional durability and chemical resistance, qualifying it for use in diverse, demanding environments. Its design features a dramatically reduced inner volume, significantly cutting down on fluid waste and enhancing the precision of fluid delivery—essential for procedures that require exact fluid dosages. The incorporation of a 4-way stopcock not only ensures seamless compatibility with industrial-standard syringes but also offers advanced control over fluid direction, eliminating the need for additional adapters and simplifying the procedural setup, thus facilitating a more efficient and effective workflow.
