A New Heart Valve That Replaces Old Ones Without Open Surgery

This patent describes a prosthetic heart valve that can be inserted without major surgery, using an expandable support and special arms to hold it in place within the heart.

Granted 2026ActiveExpires 2043

Original patent title: “Prosthetic heart valve devices and associated systems and methods”

Plain-English explanation by SahiLast reviewed · September 28, 2026

This patent describes a prosthetic heart valve that can be inserted without major surgery, using an expandable support and special arms to hold it in place within the heart. Granted in 2026.

Coverage

What does this patent actually cover?

This technology describes a prosthetic heart valve designed for percutaneous replacement, meaning it's inserted through a small incision rather than open-heart surgery. The device includes an expandable support that fits between the natural valve's leaflets. Crucially, it features multiple asymmetrically arranged arms. These arms are designed to securely hold the native valve's leaflets between themselves and the outer surface of the expandable support. Some versions of these arms also have tip portions that engage the subannular surface of the native valve, providing extra stability.

The gap

What does this patent NOT cover?

  • Does not cover heart valve replacements requiring traditional open-heart surgery, as it specifically focuses on percutaneous methods.
  • Does not cover prosthetic valves that lack asymmetrically arranged arms for securing native valve leaflets.
  • Does not cover devices that do not engage the subannular surface of the native valve with tip portions, if that specific engagement is absent.
  • Does not cover prosthetic valves that are not expandable or do not use an expandable support structure.
  • Does not cover non-valve cardiac implants, such as stents for arteries or pacemakers.

These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.

What made this novel

The noveltynoveltyThe requirement that an invention be different from anything publicly known before its priority date.Read more → lies in the specific design for securing the new valve: using asymmetrically arranged arms that grip the native valve's leaflets and tip portions that engage the subannular surface. This combination provides a stable fit for a percutaneously delivered valve, which is a significant engineering challenge.

Why it matters

The bigger picture

Replacing a damaged heart valve is a critical medical procedure, and traditional open-heart surgery carries significant risks and recovery times. This patent focuses on less invasive, percutaneous methods, which can offer patients quicker recovery, fewer complications, and broader access to life-saving treatments. Such innovations are vital for improving patient outcomes and expanding the treatable population for heart valve diseases.

Market context

Who's building on this

Companies in this space

Major medical device companies like Edwards Lifesciences, Medtronic, and Abbott Laboratories are actively developing and refining transcatheter heart valve technologies. These companies continually innovate to improve valve durability, delivery systems, and patient outcomes for percutaneous heart valve replacement.

Market impact

The development of percutaneous heart valve replacement technologies has dramatically expanded treatment options for patients, particularly those considered high-risk for open-heart surgery. This has created a rapidly growing market segment within cardiovascular devices, driving significant investment in research and development and fostering competition among leading medical technology firms to offer less invasive solutions.

Claim 1 — Plain English

What this patent covers

This technology describes a prosthetic heart valve designed for percutaneous replacement, meaning it's inserted through a small incision rather than open-heart surgery. The device includes an expandable support that fits between the natural valve's leaflets. Crucially, it features multiple asymmetrically arranged arms. These arms are designed to securely hold the native valve's leaflets between themselves and the outer surface of the expandable support. Some versions of these arms also have tip portions that engage the subannular surface of the native valve, providing extra stability.

The clever bit

The novelty lies in the specific design for securing the new valve: using asymmetrically arranged arms that grip the native valve's leaflets and tip portions that engage the subannular surface. This combination provides a stable fit for a percutaneously delivered valve, which is a significant engineering challenge.

What it does not cover

  • Does not cover heart valve replacements requiring traditional open-heart surgery, as it specifically focuses on percutaneous methods.
  • Does not cover prosthetic valves that lack asymmetrically arranged arms for securing native valve leaflets.
  • Does not cover devices that do not engage the subannular surface of the native valve with tip portions, if that specific engagement is absent.
  • Does not cover prosthetic valves that are not expandable or do not use an expandable support structure.
  • Does not cover non-valve cardiac implants, such as stents for arteries or pacemakers.
