DELIVERY TUBE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18635275 titled 'DELIVERY TUBE

The patent application describes a left-ventricular assist device with an impeller for the subject's left ventricle and a delivery tube passing through the subject's aorta.

• The delivery tube has varying flexural rigidity along its length, with different portions designed to traverse different parts of the cardiovascular system.
• The first portion of the delivery tube, passing through the aortic valve, has lower flexural rigidity compared to the second portion, which traverses the aortic arch, and the third portion, which traverses the descending aorta.

Potential Applications:

• This technology can be used in patients with heart failure or other cardiac conditions to provide mechanical circulatory support.
• It can assist in maintaining adequate blood flow and reducing the workload on the heart.

Problems Solved:

• Provides a minimally invasive method for delivering mechanical circulatory support to the left ventricle.
• Offers a more flexible and adaptable delivery system for navigating the complex anatomy of the cardiovascular system.

Benefits:

• Improved patient outcomes by providing effective circulatory support.
• Reduced risk of complications associated with traditional open-heart surgery.

Commercial Applications:

• Medical device companies can develop and market this technology for use in hospitals and cardiac care centers.
• Potential for collaboration with healthcare providers to integrate this device into existing treatment protocols.

Questions about Left-Ventricular Assist Device: 1. How does the varying flexural rigidity of the delivery tube improve the effectiveness of the left-ventricular assist device? 2. What are the potential long-term benefits of using this device for patients with heart failure?

Original Abstract Submitted

Apparatus and methods are provided, including a left-ventricular assist device that includes an impeller configured for insertion into a subject's left ventricle. A delivery tube passes through the subject's aorta, from outside the subject into the left ventricle. The delivery tube includes an outer layer that varies along a length of the delivery tube such that a flexural rigidity of the delivery tube at a first portion of the delivery tube, which is configured to traverse the aortic valve, is less than the flexural rigidity at a second portion, which is configured to traverse at least a portion of the aortic arch, and the flexural rigidity at the second portion is less than the flexural rigidity at a third portion, which is configured to traverse the descending aorta. Other applications are also described.
