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. 11,857,426.

Summary of the Inventive Concept

An innovative system for soft tissue connection to prostheses, featuring advanced fixation devices and prostheses with improved tissue integration, adjustable tension, and real-time feedback, enhancing joint replacement surgery outcomes.

Background and Problem Solved

The original patent disclosed fixation devices and prostheses for soft tissue connection, but had limitations in terms of tissue integration, surgical time, and adaptability to varying patient anatomies. The new inventive concept addresses these limitations by introducing bioactive materials, modular stems, variable geometry keels, self-locking mechanisms, and real-time feedback systems, resulting in improved tissue integration, reduced surgical time, and enhanced customization.

Detailed Description of the Inventive Concept

The enhanced fixation devices feature porous surfaces treated with bioactive materials to facilitate bone ingrowth and secure soft tissue connection. The prostheses comprise modular stems and keels with variable geometry to accommodate different patient anatomies. The filamentary fixation devices have adjustable tension to accommodate varying soft tissue conditions and self-locking mechanisms to reduce surgical time. Additionally, the system includes sensors to monitor tissue tension and feedback loops to adjust the tension in real-time, ensuring optimal tissue integration. The inventive concept also enables customization of joint replacement prostheses using additive manufacturing techniques and 3D modeling.

Novelty and Inventive Step

The new claims introduce novel features such as bioactive materials, modular stems, variable geometry keels, self-locking mechanisms, and real-time feedback systems, which are not present in the original patent. These features provide a significant improvement in tissue integration, surgical time, and customization, making the inventive concept non-obvious and novel.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different bioactive materials, varying the geometry of the keel, or incorporating additional sensors to monitor other tissue parameters. Variations could also include using different manufacturing techniques, such as 3D printing, to create customized prostheses.

Potential Commercial Applications and Market

The enhanced fixation devices and prostheses have significant commercial potential in the orthopedic industry, particularly in joint replacement surgery. The target market includes hospitals, clinics, and orthopedic surgeons, with potential for expansion into related fields such as sports medicine and rehabilitation.
