This report discusses the design of two devices that replace a diseased heart valve using minimally invasive surgery. First, it defines the design problem and outlines the deign criteria. Secondly, it introduces the heart structure and function. Thirdly, it describes the need for this project. The reader is then introduced to currently available heart valve and stent technology and their design criteria. A discussion of patent searches proving that no current technology meets the design criteria follows. Next, it introduces the final design and outlines the procedure followed to achieve this design. Following this is the material selection process for the design. This report then explains the testing and analysis performed. Finally, it informs the reader of manufacturers contacted for prototyping and further testing required to finish the design.
