Title: Innovations by Mohamed M Marei in Septum Technology

Introduction

Mohamed M Marei, an inventive mind based in Louisville, KY, has made significant contributions to the field of medical device technology. With a total of four patents to his name, Marei focuses primarily on enhancing the functionality of septums in injection systems, thereby improving safety and efficiency in medical procedures.

Latest Patents

Among his latest innovations are two notable patents that showcase his ingenuity:

1. **Chambered Septum**: This innovative septum design includes at least one internal chamber along its central axis. The chamber is engineered to provide relief space, allowing the sealing sections of the septum to deform as a needle passes through. This design minimizes the surface area contact and friction between the septum and needle, which significantly reduces the risk of septum tearing and the generation of particulate matter due to abrasion.

2. **Duckbill Septum**: Marei's duckbill septum incorporates a duckbill valve assembly featuring a plurality of elastomeric ribs that extend from the body of the septum. When the septum is inserted into an injection port cavity, the interference fit generates a force transmitted by the ribs to the duckbill valve assembly. These ribs are designed to reversibly collapse at a hinge point when a needle is inserted, assisting in centering the needle while reducing wear on the valve assembly.

Career Highlights

Marei has had the opportunity to work with prominent organizations throughout his career. Notably, he has made valuable contributions to **Chromatography Research Supplies, Inc.** and the **University of Louisville Research Foundation, Inc.** His work in these institutions has further facilitated his groundbreaking innovations in septum technology.

Collaborations

Throughout his career, Marei has collaborated with several esteemed colleagues, including Christopher A. Carlisle and David L. Jones. These collaborations have played a pivotal role in accelerating the development and commercialization of his inventions.

Conclusion

Mohamed M Marei stands out as a prolific inventor in the field of medical devices, particularly with his innovative septum designs that address critical issues in injection technology. His patents not only enhance the safety and efficiency of medical procedures but also reflect his commitment to advancing healthcare through continuous innovation.
