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. 11,857,377.

Summary of the Inventive Concept

A novel ingress-egress apparatus designed for surgical implant removal in high-altitude, disaster relief, extreme weather, remote, and high-security environments, providing enhanced protection and versatility in unique operational settings.

Background and Problem Solved

The original ingress-egress apparatus for surgical implant removal has limitations in its adaptability to diverse environments. This new concept addresses the need for specialized variations of the apparatus to cater to specific, niche markets and extreme operational conditions.

Detailed Description of the Inventive Concept

The inventive concept comprises an ingress-egress apparatus with adaptability features for high-altitude environments, disaster relief situations, extreme weather conditions, remote areas, and high-security environments. The apparatus may include a sterilization module, integrated power source, weather-resistant housing, heating module, self-contained sterilization module, rechargeable power source, encrypted communication module, and biometric authentication module. These features enable the apparatus to operate effectively in a wide range of environments, ensuring the protection of the surgical work site during implant removal.

Novelty and Inventive Step

The new claims introduce novel features that distinguish the inventive concept from the original patent. The inventive step lies in the adaptation of the ingress-egress apparatus to specific, niche markets and extreme operational conditions, providing a unique solution for surgical implant removal in these environments.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include modular designs, adjustable components, and interchangeable accessories to further enhance adaptability and versatility. Additionally, the apparatus could be integrated with other medical devices or systems to create a comprehensive solution for surgical implant removal.

Potential Commercial Applications and Market

The specialized ingress-egress apparatus has significant commercial potential in various industries, including healthcare, medical devices, and disaster relief. The target markets include hospitals, medical research institutions, and organizations involved in disaster response and relief efforts.

Section 103 Obviousness Analysis (PHOSITA)

▼

Field of Art

Surgical medical devices and methods for implant removal, specifically focusing on protective apparatus for surgical work sites, with expertise in medical device design, surgical instrumentation, and environmental adaptation technologies

Person of Ordinary Skill (PHOSITA) Profile

A biomedical engineer or medical device designer with advanced degree, 5-7 years experience in surgical instrumentation, familiar with medical device adaptation strategies, environmental engineering principles, and surgical procedural requirements

Obviousness Rationale

A person of ordinary skill would recognize that the source patent's fundamental ingress-egress apparatus design provides a flexible framework for environmental adaptation. The PTD's variations represent predictable extensions of the original surgical protection concept by adding contextual modules and specialized features that address specific operational constraints. These modifications represent standard engineering problem-solving approaches for expanding medical device utility across diverse operational environments.
