Abstract
Selective endovascular hypothermia has been used to provide cooling-induced cerebral neuroprotection, but current catheters do not support thermally-insulated transfer of cold infusate, which results in an increased exit temperature, causes hemodilution, and limits its cooling efficiency. Herein, air-sprayed fibroin/silica-based coatings combined with chemical vapor deposited parylene-C capping film was prepared on catheter. This coating features in dual-sized-hollow-microparticle incorporated structures with low thermal conductivity. The infusate exit temperature is tunable by adjusting the coating thickness and infusion rate. No peeling or cracking was observed on the coatings under bending and rotational scenarios in the vascular models. Its efficiency was verified in a swine model, and the outlet temperature of coated catheter (75 μm thickness) was 1.8-2.0 °C lower than that of the uncoated one. This pioneering work on catheter thermal insulation coatings may facilitate the clinical translation of selective endovascular hypothermia for neuroprotection in patients with acute ischemic stroke.
