AI Technical Summary

Benefits of technology

This solution reduces the risk of air emboli, shortens priming times, simplifies the extracorporeal circuit, and minimizes the need for blood transfusions by effectively removing air and reducing hemodilution, thereby enhancing surgical safety and efficiency.

Problems solved by technology

In some cases, some amount of the air inside of the oxygenator may be difficult to remove during the priming procedure.

Embodiment Construction

[0024]This document describes devices used during surgical procedures for treatment of heart conditions. For example, this document describes extracorporeal heat exchange and oxygenation devices that can be used for on-pump open-heart surgery to facilitate surgical procedures such as coronary artery bypass grafting. Some extracorporeal heat exchange and oxygenation devices described herein can include an integrated air removal structure.

[0025]Referring to FIG. 1, a patient 10 can receive medical treatment while using an exemplary extracorporeal blood flow circuit 100. In this illustrative example, the patient 10 is undergoing a heart bypass procedure using the extracorporeal blood flow circuit 100. The circuit 100 is connected to the patient 10 at the patient's heart 12. Blood from the patient 10 is extracted from the patient 10 at the patient's heart 12; the blood is circulated through the circuit 100; and the blood is then returned to the patient's heart 12.

[0026]The example extra...

Abstract

Extracorporeal blood flow circuit devices can be used during medical procedures such as on-pump open-heart surgery. For example, extracorporeal heat exchange and oxygenation devices can be used to facilitate surgical procedures such as coronary artery bypass grafting. In some embodiments, such an oxygenation device can include an integrated air removal structure. In particular embodiments, the air removal structure can comprise one or more porous hollow fibers.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 62 / 572,754, filed Oct. 16, 2017. The disclosure of the prior application is considered part of (and is incorporated by reference in) the disclosure of this application.BACKGROUND1. Technical Field[0002]This document relates to devices used during surgical procedures for treatment of heart conditions. For example, this document relates to extracorporeal heat exchange and oxygenation devices that can be used for on-pump open-heart surgery to facilitate surgical procedures such as coronary artery bypass grafting. Some extracorporeal heat exchange and oxygenation devices described in this document include an integrated air removal structure.2. Background Information[0003]Hollow fiber oxygenators are utilized within the extracorporeal circuit to meet a patient's gas exchange needs during cardiopulmonary bypass surgery. Blood from the patient is either gravity drained,...
