Here is the list of valve manufacturers I have. If any of this is incorrect or if there are any omissions or additions/updates please advise:

Note: Biological is simply another name for “Tissue”, and Biological Valves are either Bovine (cow), Porcine (pig), or Equine (horse). There are also valves called “Homografts” or “Allografts” that are from cadavers.
Note: Mechanical heart valves today are all the “Bileaflet” design except for the Medtronic mechanical valve, which is the “Tilting Disc” design. In the past there was also the “Ball and Cage” design, but this design is no longer sold in the U.S.
Note: Some of the above also sell products for valve repair (versus valve replacement)
