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. 11,857,736.

Summary of the Inventive Concept

An improved modular medical device catheter system with advanced adapter designs, enhancing securement, flexibility, and ease of use during medical procedures.

Background and Problem Solved

The original modular medical device catheter system had limitations in terms of securement, flexibility, and ease of use. The new inventive concept addresses these limitations by introducing advanced adapter designs that provide improved securement, reduced risk of dislodgement, and enhanced flexibility during medical procedures.

Detailed Description of the Inventive Concept

The enhanced modular medical device catheter system features an adapter with an improved coil design that self-adjusts to the medical device's lumen size during use, ensuring securement and reducing the risk of dislodgement. Additionally, the adapter's proximal portion can be coated with a friction-reducing material to facilitate smooth insertion and minimize damage to the catheter's lumen. Furthermore, the adapter can be designed with a temperature-sensitive material that expands or contracts in response to changes in body temperature, providing a dynamic securement mechanism. The adapter can also feature a retractable slender element that can be deployed or retracted as needed, allowing for increased flexibility and ease of use during medical procedures. The distal portion of the adapter can be designed with a textured surface to improve grip and reduce slippage during use.

Novelty and Inventive Step

The new inventive concept introduces advanced adapter designs that provide improved securement, flexibility, and ease of use, which are not obvious from the original patent. The self-adjusting coil design, friction-reducing material, temperature-sensitive material, retractable slender element, and textured surface are all novel features that distinguish the new inventive concept from the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the enhanced modular medical device catheter system could include adapters with different coil designs, materials, or geometries. The temperature-sensitive material could be replaced with other dynamic securement mechanisms, such as shape-memory alloys or polymers. The retractable slender element could be designed with different deployment mechanisms or materials. These variations ensure broad conceptual coverage and adaptability to different medical procedures and applications.

Potential Commercial Applications and Market

The enhanced modular medical device catheter system has significant commercial potential in the medical device industry, particularly in the fields of interventional cardiology, radiology, and urology. The system's improved securement, flexibility, and ease of use can reduce procedure times, minimize complications, and enhance patient outcomes, making it an attractive solution for medical professionals and hospitals.
