Enhanced Pressure Sensing Guidewires with Integrated Sensor Arrays

The present inventive concept pertains to advanced pressure sensing guidewires with integrated sensor arrays, enabling real-time pressure profiling and improved navigation through blood vessels.

The original patent, 'Pressure sensing guidewires,' has limitations in providing accurate and reliable pressure measurements, particularly in complex blood vessel geometries. The new inventive concept addresses these limitations by integrating multiple pressure sensors and temperature sensors, enabling more accurate and reliable pressure profiling.

The enhanced pressure sensing guidewire system comprises an elongated shaft with an integrated sensor array, including at least two pressure sensors spaced apart by a predetermined distance. The control unit receives pressure data from the sensor array and generates a pressure profile along the shaft. The guidewire's position can be adjusted within a blood vessel based on the generated pressure profile. Additionally, the system can include a temperature sensor to measure temperature fluctuations within the blood vessel and adjust the pressure sensing data accordingly. The flexible shaft is designed to navigate through tortuous blood vessels while maintaining accurate pressure sensing.

The new inventive concept's integrated sensor array and control unit provide a novel and non-obvious solution to the limitations of the original patent, enabling real-time pressure profiling and improved navigation through blood vessels.

Alternative embodiments of the inventive concept could include guidewires with varying sensor array configurations, different types of sensors, or alternative control unit algorithms. Additionally, the system could be adapted for use in other medical applications, such as cardiac catheterization or neurovascular interventions.

The enhanced pressure sensing guidewire system has significant commercial potential in the medical device industry, particularly in the fields of interventional cardiology and neurovascular medicine. The system's ability to provide real-time pressure profiling and improved navigation through blood vessels could lead to improved patient outcomes and reduced procedure times.
