PROSTHETIC VALVES WITH EVERTING ANCHORS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18664760 titled 'PROSTHETIC VALVES WITH EVERTING ANCHORS

Simplified Explanation:

This patent application describes a prosthetic valve with anchor arms that can engage surrounding tissue to secure the valve within a native heart valve.

• The prosthetic valve includes an expandable valve frame and leaflets supported within it.
• Elongate anchor arms extend from the valve frame's outlet end, with anchoring protrusions like barbs for tissue engagement.
• During delivery, the anchor arms face inwardly, but upon release, they evert to engage surrounding tissue outwardly.

Key Features and Innovation:

• Expandable valve frame with leaflets for heart valve replacement.
• Elongate anchor arms with anchoring protrusions for tissue engagement.
• Eversion mechanism for the anchor arms to secure the prosthetic valve within a native heart valve.

Potential Applications:

• Minimally invasive heart valve replacement procedures.
• Treatment of heart valve diseases and conditions.
• Improving patient outcomes and quality of life.

Problems Solved:

• Secure attachment of prosthetic valves within native heart valves.
• Enhanced stability and functionality of prosthetic heart valves.
• Facilitation of minimally invasive heart valve replacement procedures.

Benefits:

• Improved treatment options for heart valve diseases.
• Reduced risks of complications during heart valve replacement surgeries.
• Enhanced patient recovery and quality of life post-procedure.

Commercial Applications:

Title: Innovative Prosthetic Valve Technology for Heart Valve Replacement

Potential commercial uses include:

• Medical device companies specializing in heart valve technologies.
• Hospitals and healthcare facilities offering advanced cardiac care services.
• Research institutions focusing on cardiovascular innovations.

Questions about Prosthetic Valve Technology:

1. How does the eversion mechanism of the anchor arms contribute to the secure attachment of the prosthetic valve?

  - The eversion mechanism allows the anchor arms to engage surrounding tissue outwardly, ensuring a stable and secure fit within the native heart valve.

2. What are the potential long-term benefits of using this innovative prosthetic valve technology for patients with heart valve diseases?

  - The long-term benefits may include improved heart function, reduced risks of complications, and enhanced quality of life for patients undergoing heart valve replacement procedures.

Original Abstract Submitted

A prosthetic valve includes an expandable valve frame and leaflets supported therein. A plurality of elongate anchor arms extends from an outlet end portion of the valve frame. Each elongate anchor arm includes anchoring protrusions, such as barbs, for engaging surrounding tissue. During delivery to the treatment site, the anchoring protrusions face inwardly. When released from the delivery catheter, the anchoring arms evert such that the anchoring protrusions reverse orientation and face outwardly. In this position, the protrusions can engage surrounding tissue and thereby secure the prosthetic valve within a native heart valve.
