Implantable Prosthetic Valves

Brief Description

The invention pertains to a prosthetic valve featuring a saddle-shaped annulus that synchronously transforms between concave and convex configurations, facilitating seamless opening and closure synchronized with cardiac cycles. Comprising leaflets and support elements, the valve mimics natural heart valve function, enabling effective blood flow regulation and offering versatile deployment options for cardiac and vascular applications.

Suggested uses

The prosthetic valve described in the patent is suggested for use as a replacement for dysfunctional heart valves or similar organs, such as venous valves. It can be deployed in various positions within the heart, including the mitral and aortic positions, as well as in right-sided heart valves like the pulmonary and tricuspid valves. Additionally, it offers potential applications in vascular surgeries and other body channels where a functional valve is required for proper flow regulation.

Features/Benefits

·Saddle-Shaped Annulus:

The valve incorporates a saddle-shaped annulus, allowing for synchronized transformation between concave and convex configurations in response to pressure changes.

The valve includes leaflets made of various materials such as synthetic material, biological tissue, or pericardial tissue, ensuring effective sealing and flow regulation.

Technology Description

The prosthetic valve technology described in the patent innovatively utilizes a saddle-shaped annulus, mimicking the function of natural heart valves. This annulus undergoes synchronized transformation between concave and convex configurations in response to pressure changes within the cardiac chambers. This transformation enables seamless opening and closure of the valve, synchronized with the cardiac cycle, ensuring efficient blood flow regulation. The valve comprises leaflets and support elements extending from the annulus, which maintain proper positioning and function of the valve components. Leaflets can be made of synthetic materials, biological tissues, or pericardial tissue sourced from various animals, enhancing biocompatibility and durability. Support elements aid in preventing leaflet prolapse and contribute to the valve's stability during operation. The valve components are constructed from super-elastic or elastic materials, including shape memory materials like nickel titanium alloys, ensuring resilience and longevity. Versatile deployment methods, including minimally invasive approaches, offer flexibility in surgical procedures, expanding the valve's applicability across different patient populations and surgical scenarios. Additionally, the valve can be loaded with bioactive agents, enhancing therapeutic potential for targeted treatment delivery. Overall, this technology represents a significant advancement in prosthetic valve design, addressing key challenges in cardiac surgery and improving patient outcomes.
