Embodiment Construction

[0033] Certain illustrative embodiments will be described in order to provide an overall understanding of the systems, methods, and devices described herein. Although the embodiments and features described herein are described specifically for use with a percutaneous blood pump system, it should be understood that all components and other features outlined below may be combined with each other in any suitable manner and may be adapted and applied to other Types of heart treatments and heart assist devices, including heart assist devices implanted using surgical incisions, etc. Additionally, although the application of the pump element has been described herein with respect to a blood pump, it should be understood that the pump element can be applied to other pumps where any type of fluid flow sent distally can travel proximally and damage the electronics. part. For example, pumps used in sour or otherwise corrosive environments may require purge streams to prevent the ingress...

Abstract

Systems and methods are described herein relating to an intracardiac blood pump system comprising a pump, an elongate multi-lumen catheter, a compartment connected to the catheter, a first lumen, a conduit and a filter disposed within die conduit. At least one electronic element is located within the compartment. The conduit extends through an interface between the compartment and the catheter. The conduit is configured to allow gas to penetrate from a first end of the conduit through the first opening of the compartment to a second end of the conduit. The second end of the conduit is in fluid communication with a central lumen of the elongate multi-lumen catheter. The filter is configured to prevent egress of liquid from the multi-lumen catheter into the compartment after allowing flow of gas from the first end of the conduit through the second end of the conduit and into the multi-lumen catheter.

Description

[0001] References to related applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 700,683, filed July 19, 2018, entitled "SYSTEMS AND METHODS FOR REDUCING LEAKS FROM A CATHETER," and rights and interests. The entire content of the above application is incorporated herein by reference. Background technique [0003] An intracardiac heart pump assembly can be introduced surgically or percutaneously into the heart and used to transport blood from one location in the heart or circulatory system to another location in the heart or circulatory system. For example, when deployed in the heart, an intracardiac pump can pump blood from the left ventricle of the heart into the aorta, or from the right ventricle into the pulmonary artery. The intracardiac pump can be powered by a motor located outside the patient or by a motor located inside the patient. Some intracardiac blood pumping systems are able to run in parallel with the natural h...
