This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,365.

Summary of the Inventive Concept

A novel dual lumen catheter system designed for high-security, real-time tissue sampling and medicant delivery, as well as for use in disaster relief and extreme weather conditions.

Background and Problem Solved

The original dual lumen catheter patent has limitations in its range of motion and diagnostic capabilities, particularly in high-security environments and extreme weather conditions. The new inventive concept addresses these limitations by adapting the dual lumen catheter for specialized applications.

Detailed Description of the Inventive Concept

The new inventive concept comprises a dual lumen catheter system with a fully enclosed lumen for receiving a medical device and an open trough for receiving an imaging probe. The system is designed for high-security environments and includes a secure data transmission module for encrypting and transmitting ultrasound images and medical device data to a remote monitoring station. Additionally, the catheter is coated with a water-repellent material and includes a temperature-resistant material for withstanding extreme temperatures, making it suitable for use in disaster relief and extreme weather conditions.

Novelty and Inventive Step

The new claims introduce novel features such as secure data transmission, reinforced materials, and water-repellent coatings, which are not present in the original patent. These features provide a non-obvious solution to the problem of adapting the dual lumen catheter for high-security and extreme environment applications.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the material composition of the catheter, adjusting the dimensions of the lumens, or incorporating additional features such as sensors or actuators. Variations could also include adapting the system for use in other specialized environments, such as space exploration or search and rescue operations.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the medical device industry, particularly in the areas of high-security medical facilities, disaster relief, and extreme weather response. The system could also be marketed to government agencies, military organizations, and other entities that require secure and reliable medical solutions in challenging environments.
