Summary of the Inventive Concept
The inventive concept integrates a dual-lumen catheter with distinct technologies, such as AI, IoT, blockchain, nanomaterials, MEMS sensors, and 3D printing, to create a more powerful system for ultrasound-guided tissue sampling, enabling real-time analysis, remote monitoring, and customized sampling devices.
Background and Problem Solved
The original patent, 'Dual Lumen Catheter,' addressed the limitations of current tools for ultrasound visualization and sampling of peripheral lung tumors. However, it did not leverage advancements in AI, IoT, blockchain, and other technologies to enhance the diagnostic and therapeutic capabilities of the catheter. The new inventive concept solves this problem by integrating these technologies to create a more comprehensive and effective system.
Detailed Description of the Inventive Concept
The inventive concept comprises a dual-lumen catheter, an artificial intelligence module, an IoT network, a blockchain-based data storage system, a nanomaterial-based coating, a MEMS sensor, and a 3D printing module. The AI module analyzes ultrasound images obtained through the catheter and stores the analysis results in the blockchain-based data storage system, ensuring secure and transparent data management. The IoT network enables remote monitoring and control of the catheter during the sampling procedure, while the nanomaterial-based coating enhances the catheter's biocompatibility. The MEMS sensor provides real-time feedback during the sampling procedure, and the 3D printing module creates customized sampling devices based on the identified optimal sampling locations.
Novelty and Inventive Step
The new claims introduce a synergistic combination of distinct technologies, which is not obvious from the original patent. The integration of AI, IoT, blockchain, nanomaterials, MEMS sensors, and 3D printing with the dual-lumen catheter provides a novel and non-obvious solution for ultrasound-guided tissue sampling.
Alternative Embodiments and Variations
Alternative embodiments of the inventive concept could include integrating the dual-lumen catheter with other technologies, such as robotic assistance, augmented reality, or advanced biomaterials. Variations could include adapting the system for different medical procedures or applications, such as cardiovascular or neurological interventions.
Potential Commercial Applications and Market
The inventive concept has significant commercial potential in the medical device industry, particularly in the fields of interventional pulmonology, oncology, and cardiology. The system's ability to provide real-time analysis, remote monitoring, and customized sampling devices could revolutionize the diagnostic and therapeutic landscape, offering improved patient outcomes and reduced healthcare costs.
