Hall-Kaster Prostetic Heart Valve

Description (Brief)
The Hall-Kaster artificial heart valve has a pivotal Pyrolyte disk design, and a titanium cage. The sewing ring is covered in woven Teflon. A hole in the center of the disk is held in place by a central strut and two smaller struts emanating from the outer flange. Introduced in 1977, the Hall-Kaster valve was manufactured by Medtronic, and the name was later changed to the Medtronic-Hall heart valve.
