ABSTRACT:
A system, apparatus and method for tanning of a stentless aortic bioprosthesis, and articles manufactured by such method. The system includes a circulating bath which contains a tanning solution, and a support insert apparatus upon which the bioprosthesis is mounted during the tanning prosthesis. The support insert has i) two (2) coronary Sinus of Valsalva support projections for maintaining the coronary Sinuses of Valsalva in their substantially open, non-collapsed configurations, and ii) one (1) non-coronary Sinus of Valsalva support projection for maintaining the non-coronary Sinus of Valsalva in its substantially open, non-collapsed configuration, during tanning. Additionally, the system may include internal or external support members for maintaining the patency of right and left coronary artery segments, such coronary artery segments being permitted to remain attached to the Aortic bioprosthesis during tanning.
