CRIMPING DEVICES AND METHODS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18607271 titled 'CRIMPING DEVICES AND METHODS
Simplified Explanation: The patent application describes devices and methods for crimping a prosthetic heart valve onto a delivery device. Valves are crimped over an inflatable balloon between proximal and distal shoulders mounted on a shaft inside the balloon.
- Crimping methods involve multiple compression steps with the valve in different axial positions relative to the crimping jaws at each step.
- The valve may extend partially outside the crimping jaws during certain steps, applying crimping force only to the part inside the jaws.
- Exemplary crimping devices have two or more sets of jaws closing down to different inner diameters, compressing different parts of the valve to different outer diameters simultaneously.
Key Features and Innovation: - Crimping prosthetic heart valves onto delivery devices - Multiple compression steps with axial positioning - Partial extension of valve outside crimping jaws - Different inner diameters for simultaneous compression
Potential Applications: This technology can be used in the medical field for minimally invasive heart valve replacement procedures.
Problems Solved: - Facilitates secure attachment of prosthetic heart valves - Enables precise crimping process for accurate placement
Benefits: - Improved accuracy in valve crimping - Enhanced safety during heart valve replacement procedures
Commercial Applications: Title: Innovative Prosthetic Heart Valve Crimping Technology This technology can be utilized by medical device manufacturers and healthcare providers for advanced heart valve replacement surgeries, potentially improving patient outcomes and reducing procedural risks.
Prior Art: Prior art related to this technology may include patents or research papers on minimally invasive heart valve replacement procedures and devices.
Frequently Updated Research: Researchers may be exploring further advancements in prosthetic heart valve crimping techniques to enhance efficiency and effectiveness in heart valve replacement surgeries.
Questions about Prosthetic Heart Valve Crimping: 1. How does this technology improve the accuracy of heart valve replacement procedures? 2. What are the potential implications of using this innovative crimping method in the medical field?
Original Abstract Submitted
Devices and methods for crimping a prosthetic heart valve onto a delivery device are described. In some embodiments, valves are crimped over an inflatable balloon and between proximal and distal shoulders mounted on a shaft inside the balloon. Crimping methods can include multiple compression steps with the valve located in different axial positions relative to the crimping jaws at each different step. In some methods, the valve may extend partially outside of the crimping jaws during certain crimping steps, such that the crimping force is only applied to the part of the valve that is inside the jaws. Exemplary crimping devices can include two or more adjacent sets of jaws that close down to different inner diameters, such that different parts of a valve get compressed to different outer diameters at the same time during a single crimping step.
