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. 11,856,946.

Background and Problem Solved

The original patent disclosed a chamber for transplantation with a membrane for immunoisolation, which has limitations in terms of monitoring and controlling environmental conditions, securely storing and sharing recipient biological data, and enhancing biocompatibility. The present invention addresses these limitations by incorporating advanced technologies to create a more comprehensive and effective system for transplantation.

Novelty and Inventive Step

The present invention is novel and non-obvious in that it combines a chamber for transplantation with a membrane for immunoisolation and other distinct technologies to create a more comprehensive and effective system for transplantation. The integration of these technologies provides a synergistic effect, enhancing the overall functionality and performance of the system.

Alternative Embodiments and Variations

Alternative embodiments of the invention may include using different types of membranes for immunoisolation, such as porous membranes containing polymers, or integrating the chamber with other advanced technologies, such as robotics or virtual reality. The invention can also be adapted for use in different applications, such as organ transplantation or tissue engineering.

Potential Commercial Applications and Market

The present invention has significant commercial potential in the field of transplantation and regenerative medicine. It can be marketed to hospitals, research institutions, and biotechnology companies, and can be used to develop new products and services for transplanting biological constituents. The invention can also be licensed to other companies, generating revenue through royalties.
