Anatomically correct shape
Unique uncrimped section that does not stretch:
- allows for easy sewing of valve remnants, or prosthetic valve within the tube to simplify the procedure
- facilitates estimation of the length required for placement of valve remnants or prosthetic valve
- can be precisely trimmed and shaped in case of remodeling technique procedures.
3 reference lines act as a guide for prosthetic valve or valve remnants anastomosis.
Valve sparing procedures
The proximal collar can be used for prosthetic valve sewing or trimmed/inverted for valve sparing procedures.

Intergard Woven Thoracic Aortic Graft
A woven graft with an uncrimped section to reconstruct or replace the thoracic ascending aorta.
Single use graft sizers are designed to aid the physician in determining the size of the lumen of the host vessel in order to select the appropriate graft diameter.
Tape materials are constructed of tightly braided polyester. These tapes are superior in strength and less traumatizing than cotton because they will not absorb blood and stick to tissue.
