Title: Mary Johnson: Innovator in Prosthetic Heart Valve Technology
Introduction
Mary Johnson is a prominent inventor based in Saint Paul, MN (US), known for her significant contributions to the field of cardiology. With a total of five patents to her name, she has made remarkable advancements in the design and assembly of prosthetic heart valves. Her innovative approaches have the potential to improve patient outcomes and enhance the quality of life for those with heart conditions.
Latest Patents
Among her latest patents is a method of assembling a prosthetic heart valve that includes a collapsible and expandable stent. This stent features an annulus section and an aortic section, with the annulus section having a first diameter in a relaxed condition and a second diameter that is less than the first in a collapsed condition. A constraint is applied to the stent to maintain the annulus section at a predetermined diameter between the two states. By applying a cuff and/or a plurality of leaflets to the stent in this constrained condition, less material is utilized, allowing the resultant prosthetic valve to be collapsed to a smaller diameter for easier introduction into a patient.
Another notable patent by Johnson is similar in nature, focusing on the assembly of a prosthetic heart valve using the same innovative stent design. This method also emphasizes the importance of reducing material usage while ensuring the valve can be effectively collapsed for patient introduction.
