VENTRICULAR ASSIST DEVICE WITH DISTAL THRUST BEARING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18652956 titled 'VENTRICULAR ASSIST DEVICE WITH DISTAL THRUST BEARING

Simplified Explanation: The patent application describes a ventricular assist device with an impeller that pumps blood, a frame around the impeller, and a distal thrust bearing to prevent axial motion of the shaft in response to pressure variations. The frame and connecting struts are formed as a single integral body.

The invention is a ventricular assist device with an impeller that pumps blood.
A frame surrounds the impeller to provide structural support.
A distal thrust bearing prevents axial motion of the shaft in response to pressure changes.
Connecting struts link the thrust bearing to the frame, forming a single integral body.
The design ensures stable operation of the device during blood pumping.

Potential Applications: 1. Medical devices for heart failure patients. 2. Cardiac surgery equipment. 3. Research and development in cardiovascular medicine.

Problems Solved: 1. Prevents axial motion of the shaft during blood pumping. 2. Ensures stable operation of the ventricular assist device. 3. Improves efficiency and reliability of blood circulation support systems.

Benefits: 1. Enhanced safety and stability during blood pumping. 2. Increased longevity and durability of the device. 3. Improved performance in supporting heart function.

Commercial Applications: The ventricular assist device can be used in hospitals, cardiac care centers, and research institutions for patients with heart failure. It has the potential to improve outcomes in cardiac surgery and critical care settings.

Prior Art: Prior art related to ventricular assist devices and blood pump technologies can be found in medical journals, patent databases, and academic research papers.

Frequently Updated Research: Ongoing research in cardiovascular medicine, medical device engineering, and biomechanics may provide further insights into the design and optimization of ventricular assist devices.

Questions about Ventricular Assist Devices: 1. How does the design of the ventricular assist device contribute to its stability and efficiency? 2. What are the potential challenges in implementing this technology in clinical settings?

Original Abstract Submitted

Apparatus and methods are described including a ventricular assist device that includes an axial shaft and an impeller disposed on the axial shaft, the impeller being configured to pump blood. A frame is disposed around the impeller. A distal thrust bearing is disposed within the frame, the distal end of the axial shaft being configured to engage with the distal thrust bearing such as to prevent the axial shaft from undergoing axial motion in response to variations in the pressure gradient against which the impeller pumps blood. A plurality of connecting struts extend radially inwardly from the frame to the distal thrust bearing and couple the thrust bearing to the frame. The frame and the connecting struts are formed as a single integral body. Other applications are also described.
