Valve Delivery Catheter Pressure Sensing for Real-Time Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring atrial pressures during heart valve procedures are invasive and require separate catheterization, limiting the ability to assess the efficacy of valve implants or repairs without relying heavily on imaging techniques.
Innovation Solution
A delivery system integrated with a pressure sensor within a catheter or pusher rod is used to measure atrial pressures during transcatheter valve repair or replacement procedures, eliminating the need for additional catheterization and providing more accurate pressure measurements by reducing noise and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate catheterization is used to measure atrial pressures, then pressure measurements can be obtained, but the procedure becomes more invasive and complex
Solution Approach 1:
The patent combines the pressure measurement function with the existing valve repair delivery system by integrating a pressure sensor into the delivery catheter. This merging eliminates the need for a separate pressure measurement catheter, reducing procedural complexity while maintaining measurement capability. The pressure sensor is positioned within the delivery system to measure atrial pressures during valve repair procedures.
Solution Approach 2:
The delivery system is designed to perform multiple functions: delivering the valve repair device and simultaneously measuring atrial pressures. By making the delivery system multi-functional, the patent eliminates the need for additional separate catheterization procedures, thereby reducing invasiveness and complexity while providing comprehensive monitoring during the procedure.
2Ease of operation
If imaging techniques are used to assess valve therapy efficacy, then non-invasive assessment is possible, but measurement accuracy is reduced
Solution Approach 1:
The patent replaces reliance on imaging techniques with direct mechanical pressure sensing. Instead of using imaging modalities to indirectly assess valve function, the system uses a pressure sensor to directly measure atrial pressures, providing more accurate quantitative data about valve therapy efficacy while maintaining ease of operation during the procedure.
3Measurement precision
If additional catheterization is performed for pressure measurement, then accurate pressure data is obtained, but patient trauma increases
Solution Approach 1:
By merging the pressure measurement function into the existing delivery catheter, the patent eliminates the need for additional catheterization procedures. This reduces the number of needle punctures and catheter insertions required, thereby minimizing patient trauma while maintaining the ability to obtain accurate pressure measurements during valve repair.

AI summary
Catheterization methods and apparatuses allow sensing of pressures inside the heart and for removing air from catheters. A delivery system can use the same components that are used to deliver a valve repair or replacement device to measure the pressure in the atrium or other heart chamber. A pressure sensor can be included in one of the catheters of the delivery system or pressure can be sensed through the same port that is used to flush a catheter. The delivery system can be inserted into the heart, delivering the valve repair or replacement device to the native valve, such as the mitral valve, the tricuspid valve, the aortic valve, or the pulmonary valve.
