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

A novel system and method for forming an anastomosis juncture, enabling simultaneous eversion of donor and receiving passages, precise alignment, and efficient suturing.

Background and Problem Solved

The original patent for partial eversion anastomosis juncture formation and suturing has limitations in terms of efficiency, safety, and precision. The new inventive concept addresses these limitations by introducing synchronized eversion mechanisms, integrated suction apparatus, and real-time monitoring systems, thereby enabling faster, safer, and more efficient anastomosis procedures.

Detailed Description of the Inventive Concept

The enhanced anastomosis juncture formation and suturing system comprises a donor passage eversion mechanism and a receiving passage eversion mechanism, which are synchronized to facilitate simultaneous eversion of the donor and receiving passages. The system also includes a plurality of guide sections with partial helical channels for facilitating suturing of the passages. Additionally, the system features a suction apparatus integrated with the receiving passage eversion mechanism to apply suction to the exterior surface of the distal portion of the opening of the receiving passage. The system also includes a monitoring system that tracks the eversion of the donor and receiving passages, providing real-time feedback to facilitate precise alignment of the passages. The method of forming an anastomosis juncture using this system involves simultaneously everting the donor and receiving passages, presenting the guide sections, and motivating a filament along the partial helical channel using a helical needle.

Novelty and Inventive Step

The new claims introduce the concept of synchronized eversion mechanisms, integrated suction apparatus, and real-time monitoring systems, which are not present in the original patent. These features enable simultaneous eversion, precise alignment, and efficient suturing, thereby providing a significant improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the design of the eversion mechanisms, using different types of suction apparatus, or incorporating additional features such as automated suturing or real-time imaging. Variations could also include adapting the system for use in different types of anastomosis procedures or for use in different medical specialties.

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 areas of cardiovascular, gastrointestinal, and urological surgery. The system's ability to enable faster, safer, and more efficient anastomosis procedures could lead to increased adoption and market share in these industries.

Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Surgical medical devices and methods for creating anastomosis connections, specifically focusing on passage eversion, alignment, and suturing techniques in minimally invasive surgical procedures

Person of Ordinary Skill (PHOSITA) Profile

A surgical device engineer or biomedical researcher with expertise in medical device design, surgical instrumentation, and anastomosis techniques, holding advanced degrees in biomedical engineering or medical device design with knowledge of surgical intervention methodologies

Obviousness Rationale

A person having ordinary skill would recognize that the PTD's variations represent predictable engineering improvements to the source patent's fundamental anastomosis technique. The disclosed synchronization of eversion mechanisms, integrated suction apparatus, and monitoring systems are logical extensions of the original patent's core methodology of passage eversion and suturing. These variations represent incremental technical advancements that would be obvious to a skilled practitioner seeking to optimize surgical connection procedures.

Obvious Combinations & Variations

Source Patent Element

Everting a distal portion of passage ends while maintaining proximal portions in non-everted position

PTD Variation

Synchronizing donor and receiving passage eversion mechanisms to enable simultaneous eversion

PTD Variation

Configuring helical needle to travel in a specifically defined non-linear path

Obviousness Reasoning

Modifying needle path represents a routine design variation that a PHOSITA would recognize as an obvious method of optimizing suturing technique

Source Patent Element

Forming passage openings and connections

PTD Variation

Expanding potential application across different medical specialties and anastomosis procedures

Obviousness Reasoning

Adapting the core technique to various medical contexts represents a standard approach of technological generalization familiar to skilled practitioners

35 U.S.C. § 103 Summary: Based on the teachings of US Patent 11857193, the present publication demonstrates that the claimed variations in anastomosis juncture formation represent obvious extensions of prior art, rendering subsequent claims involving synchronized eversion mechanisms, integrated suction apparatus, and real-time monitoring systems anticipated and unpatentable under 35 U.S.C. § 103, as the modifications would have been obvious to a person having ordinary skill in surgical device design at the time of invention.
