R&D/Clinical Medicine R&D engineer R&D engineer of neurovascular interventional medical devices. ● Veterinary Engineer：Drawing up the entire Neurotech preclinical animal experimental program.and finished two programs animal study. Completing biological evaluation in animal model, verifying catheter compatibility and product validity. Assisting doctor to complete the experiment and pathologic evaluation. ● Liquid embolic material： The material we developing is for the treatment of intracranial aneurysms. I have been solved: a) developing under DSA. b) Physical property test such as pushability in catheter, stickiness, diffusibility, adherence.....with DFMEA and go through clinical needs. c) Biological testing cytotoxicity, hemolysis and toxicokinetics , especially neurotoxicity(OCED 426) established a variety of testing methods. ● Embolectomy：Improve mold design material and soldering tip head. Enhance their ability to take thrombus, making the stent less harmful to the artery. Testing retracement and wire’s tip plasticity ● In charge of Microbiology Lab Established microbiological testing center, including initial equipment purchase, PQ validation about Air-conditioning system, SOP and related documents in accordance with the GMP.
