HEART VALVE PINCH DEVICES AND DELIVERY SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18522236 titled 'HEART VALVE PINCH DEVICES AND DELIVERY SYSTEMS
Simplified Explanation
The patent application describes pinch devices and access systems used to secure a prosthetic heart valve to a heart valve annulus and treat valvular insufficiency. Here are the key points:
- Pinch devices are separate expandable elements that can be deployed to the annulus before the prosthetic heart valve is advanced and deployed.
- The pinch device and prosthetic heart valve work together to clamp/pinch the heart valve leaflets, securing the prosthetic valve in place.
- A combined delivery system allows for both the pinch device and prosthetic heart valve to be delivered through a single access point, aiding in accurate deployment.
- The pinch device can have a flexible, expandable annular frame for optimal placement.
- The pinch device can be mounted near the distal end of an access sheath, with a catheter passing through the same access sheath to deliver the prosthetic heart valve.

- Potential Applications
This technology can be used in minimally invasive heart valve replacement procedures, improving accuracy and effectiveness.
- Problems Solved
This innovation addresses the challenge of securely attaching a prosthetic heart valve to the heart valve annulus, ensuring proper function and reducing the risk of complications.
- Benefits
The use of pinch devices and access systems can lead to more precise deployment of prosthetic heart valves, potentially improving patient outcomes and reducing the need for additional interventions.
- Potential Commercial Applications
This technology has the potential for commercial use in the medical device industry for heart valve replacement procedures, catering to a growing market of patients in need of such interventions.
- Possible Prior Art
Prior art may include existing devices or methods for securing prosthetic heart valves, but the specific combination of pinch devices and access systems as described in this patent application may be novel.

Original Abstract Submitted
Pinch devices and access systems that can be used to secure a prosthetic heart valve to a heart valve annulus and to treat valvular insufficiency. A pinch device can be a separate expandable element from the prosthetic heart valve that is first advanced to the annulus and deployed, after which an expandable prosthetic heart valve can be advanced to within the annulus and deployed. The two elements can clamp/pinch the heart valve leaflets to hold the prosthetic heart valve in place. The pinch device can have a flexible, expandable annular frame. A combined delivery system can deliver the pinch device and prosthetic heart valve with just a single access point and aid more accurate coaxial deployment. The pinch device can be mounted near distal end of an access sheath, and a catheter for delivering the prosthetic heart valve can be passed through a lumen of the same access sheath.
