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. 11,857,193.

Summary of the Inventive Concept

An improved system and method for forming anastomosis junctures, enhancing accuracy, efficiency, and safety through adaptive support, controlled suction, adjustable guide sections, detachable helical needles, and real-time eversion force monitoring.

Background and Problem Solved

The original patent disclosed a method and apparatus for presenting and joining an opening of a donor passage to an opening in a receiving passage. However, the existing method may not accommodate variations in patient anatomy, and the procedure may be time-consuming and prone to errors. The new inventive concept addresses these limitations by introducing a dynamic support body, controlled suction, adjustable guide sections, detachable helical needles, and real-time eversion force monitoring, ensuring more accurate, efficient, and safe anastomosis procedures.

Detailed Description of the Inventive Concept

The enhanced anastomosis juncture formation and suturing system comprises a dynamic support body that adapts to variations in patient anatomy, allowing for more accurate and efficient anastomosis procedures. The system also features a controlled suction mechanism to facilitate eversion of the receiving passage, reducing procedure time and improving suturing efficiency. Additionally, the system includes adjustable guide sections to accommodate varying passage geometries, ensuring a secure and precise anastomosis. A helical needle with a detachable tip simplifies filament motivation and reduces procedure time. Furthermore, the system is equipped with a sensor-equipped eversion mechanism that monitors and adjusts eversion forces in real-time, ensuring safe and efficient anastomosis formation.

Novelty and Inventive Step

The new inventive concept introduces a dynamic support body, controlled suction, adjustable guide sections, detachable helical needles, and real-time eversion force monitoring, which are not present in the original patent. These features provide a significant improvement over the existing method, enhancing accuracy, efficiency, and safety in anastomosis procedures.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include different materials or designs for the dynamic support body, adjustable guide sections, or helical needles. Variations may also include different suction mechanisms or eversion force monitoring systems. Additionally, the system could be adapted for use in different types of anastomosis procedures or for use in robotic-assisted surgeries.

Potential Commercial Applications and Market

The enhanced anastomosis juncture formation and suturing system has significant commercial potential in the medical device industry, particularly in the fields of cardiovascular, gastrointestinal, and urological surgery. The system's ability to improve accuracy, efficiency, and safety in anastomosis procedures makes it an attractive solution for hospitals, surgical centers, and medical professionals.
