Title: Innovations by David S Hungerford

Introduction

David S Hungerford is a notable inventor based in Cockeysville, MD (US). He has made significant contributions to the field of biomedical engineering, particularly in the development of cell-based implants. With a total of 10 patents to his name, his work has the potential to revolutionize medical treatments and improve patient outcomes.

Latest Patents

Among his latest patents is a method for fabricating cell-containing implants. This invention discloses a method of growing cells on biodegradable microcarrier particles, specifically focusing on the growth of chondrocytes for an extended period until they aggregate. These aggregated cells can be injected directly or shaped for implantation into the body. In another embodiment, the cell microcarrier aggregates are grown in a mold that conforms to the geometry of the desired body part to be replaced. An apparatus for shaping the aggregated cells is also disclosed, and the aggregated cells can be supplied in a kit.

Another significant patent is the method for composite cell-based implants. This invention outlines a method for the implantation of a combination of cells or cell-microcarrier aggregates. One component comprises a solid implantable construct, while the second component consists of an injectable formulation. For instance, the solid implant may be first implanted to fill the majority of the cavity receiving the implant. Subsequently, cells or cell-microcarrier aggregates in an injectable format may be injected into spaces surrounding the solid implant to secure it in place and promote rapid adherence to surrounding tissues.
