Implication

Preclinical evaluation demonstrates biocompatibility and low hemolysis of the DeltaStream rotary blood pump in animal models, suggesting versatility for extracorporeal circulation.

Key Points

To develop and evaluate the hydraulic, hematologic, thermal, and durability performance of the compact DeltaStream extracorporeal rotary blood pump.
Engineered an impeller design with washout holes and an embedded electric motor capable of continuous and pulsatile flow modes.
Conducted in vitro durability tests with blood substitutes to evaluate seal lifetime and assessed potential motor-induced thermal risks.
Evaluated biocompatibility, hemolysis, and thrombogenicity in animal models using the pump standalone and in simplified bypass system configurations.
In vitro evaluations confirmed adequate flow and pressure generation for cardiopulmonary bypass without thermal blood damage from the embedded motor.
Polymeric pump seals achieved operational lifespans of up to 28 days during continuous durability testing in blood substitutes.
Animal trials demonstrated high biocompatibility, low hemolysis, and marked nonthrombogenicity across single-device and simplified bypass system setups.
