| Outline of Final Research Achievements |
The research goal was pediatric/partial assist pumps without hemolysis or thrombosis at low flow, whose blood contacting surfaces were made of polymer. Partial assist pumps, KAP5-KAP8, were manufactured and evaluated. KAP6 improved the stall at low flow. KAP7 improved hemolytic property and can be used clinically up to 9000 rpm (100mmHg). Animal experiments for KAP6 and KAP7 clarified that the antithrombogenicity is not complete even at ACT>200s. Pediatric pumps, KPAP1-KPAP4, 130g in weight, 8ml in priming volume, and 27mm in outer diameter, were manufactured and evaluated. Though KPAP4 attained the necessary pump performance and hemolytic property, the antithrombogenicity was found to be incomplete.
