Pledgets
A support for the suture,
where the tissue is under tension.
Our pledgets provide durable tissue reinforcement and serve as a suture buttress for the heart and vessels: they prevent suture pull-through in tissues subject to high mechanical stress1.

patients undergoing aortic valve replacement, with or without pledgets: no difference in events at 5 years (11.7% vs 9.8%, difference not significant). International multicentre trial3.
aorta-prosthesis anastomosis techniques compared: Teflon felt sandwich with U-stitches offers the highest tensile strength. Ex vivo study, Kanazawa4.
