Combined Blood Pump and Oxygenator System for Cardiopulmonary Bypass
Summary
USPTO published patent application US20260097160A1 for a combined blood pump-oxygenator system designed for cardiopulmonary bypass procedures. The system includes a recirculation loop allowing blood to pass through the oxygenator multiple times for enhanced gas exchange. The application was filed December 10, 2025, by ten listed inventors.
What changed
USPTO published patent application US20260097160A1 for a blood pump-oxygenator system designed for cardiopulmonary bypass. The system features a recirculation loop between blood flow inlet and outlet, with a valve controlling blood flow through the loop, allowing blood to pass through the oxygenator multiple times for repeated O2 and CO2 exchange.
For medical device manufacturers and healthcare providers, this patent application signals potential future intellectual property considerations for cardiopulmonary bypass technology. Entities developing similar extracorporeal circulation systems should review their designs to assess potential infringement risks once the patent grants.

Abstract
A blood pump-oxygenator system comprises a blood pump, oxygenator, blood flow inlet, and blood flow outlet forming a circuit operable as a cardiopulmonary bypass system for extracorporeal processing of the patient's blood, wherein the first blood pump conveys blood through the circuit from the patient into the blood flow inlet, through the oxygenator and out of the blood flow outlet back into the patient. The system further comprises a recirculation loop between the blood flow inlet and blood flow outlet that accommodates the first blood pump and oxygenator, wherein the first blood pump circulates at least part of the blood in the circuit through the recirculation loop such that blood passes through the oxygenator multiple times and is repeatedly subject to exchange of O2 and CO2 within the oxygenator. A valve between the recirculation loop and blood flow outlet controls an amount of blood flowing through the recirculation loop.
