Intracardiac Pressure Sensor Clip for Adjustable Interatrial Shunting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing percutaneous interatrial shunt devices have a fixed diameter that fails to account for a patient's changing physiology, often leading to a diminishing clinical effect over time, and lack the ability to adjust sizing based on individual patient conditions, complicating future procedures and limiting therapeutic efficacy.
Innovation Solution
Intracardiac pressure monitoring devices with a clip structure and pressure sensors are implanted in the septal wall to measure left and right atrial pressures, allowing for adjustable shunt sizing and dynamic adaptation to patient conditions, incorporating a clip structure with pressure sensors to anchor the device and transmit pressure measurements for real-time adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed diameter shunt device is implanted, then the device structure is simple and easy to implant, but it fails to account for changing patient physiology and provides diminishing clinical effect over time
Solution Approach 1:
The shunt device incorporates an adjustable diameter capability, transitioning from a fixed static structure to a dynamic one that can be modified post-implantation. The shunt diameter can be adjusted based on patient response and changing physiological conditions, allowing the device to adapt over time without requiring complete removal and reimplantation.
Solution Approach 2:
The invention enables changing the key parameter of shunt diameter after implantation. By providing mechanisms to adjust the diameter parameter in response to patient physiology changes, the device maintains therapeutic efficacy throughout the treatment period rather than experiencing diminishing effects.
2Adaptability or versatility
If a single size shunt device is used, then manufacturing and inventory are simplified, but it cannot be optimized for individual patient conditions
Solution Approach 1:
The shunt device is designed to perform multiple functions: it can be implanted in a standard procedure and then adjusted to different diameters to suit various patient conditions. This universal design allows a single device type to serve multiple patient needs rather than requiring different device models.
Solution Approach 2:
The adjustable diameter mechanism enables the device to be customized for individual patient conditions after implantation, providing optimization based on patient response without complicating the manufacturing process through multiple fixed-size models.
3Reliability
If the shunt diameter is increased to improve decompression效果, then left atrial pressure reduction is enhanced, but the risk of complications and thrombus formation increases
Solution Approach 1:
The shunt diameter can be dynamically adjusted based on patient response and complication risks. If thrombus formation or other complications arise, the diameter can be reduced to mitigate these harmful effects while maintaining adequate decompression. This dynamic adjustment capability allows optimization of the therapeutic window.
Solution Approach 2:
The system incorporates monitoring of patient response and complication development, allowing feedback-driven adjustment of shunt diameter. This enables real-time optimization of the balance between therapeutic efficacy and complication prevention, reducing thrombus risk when indicated while maintaining effective decompression.
