Ambulatory lung assist device with implanted blood pump and oxygenator
First Claim
1. A portable lung assist system, comprising:
- an implantable blood pump having a pump outlet and a pump inlet configured for communication with a circulatory system of a patient at an inlet location; and
an external and portable blood oxygenator having a blood inlet releasably connectable to the pump outlet and a blood outlet releasably connectable to the circulatory system of the patient at a return location; and
a bypass conduit connectable to the blood pump, wherein the oxygenator and the bypass conduit are in continuous fluid communication with the blood pump when the blood inlet is connected to the pump outlet.

Abstract
The present disclosure provides a system for oxygenating blood. The system may include an implantable blood pump that may draw a supply of blood from the circulatory system of a mammalian subject, such as a human being. The blood pump may provide the supply of blood to an adaptor, where the supply of blood may be supplied to either or both of a first branch or second branch. The first branch may lead to an external blood oxygenator. The oxygenator may oxygenate the blood, and the blood may be returned to the circulatory system of the mammalian subject. The second branch may bypass the oxygenator and may connect to the circulatory system of the mammalian subject. In this regard, while the blood is supplied to the second branch, the oxygenator may be disconnected and blood may be prevented from entering the first branch.

19. A method of providing respiratory assistance to a patient, comprising:
-
directing blood from a system inlet at an inlet location within a circulatory system of the patient through an implantable blood pump, out of the patient, through a portable oxygenator and back to the circulatory system; disconnecting the portable oxygenator; and directing blood through the blood pump, through a blood bypass, and back to the circulatory system when the oxygenator is disconnected and when the oxygenator is reconnected. - View Dependent Claims (20)
