Vascular prostheses — synthetic grafts designed to replace or bypass diseased blood vessels — must demonstrate reliable hydraulic performance to ensure patient safety and long-term functionality. One of the critical parameters is water permeability, which defines the controlled passage of fluid through the graft wall. Proper permeability is essential: too high may cause blood leakage, while too low may hinder tissue integration and healing. That’s why ISO 7198 requires rigorous water permeability testing as part of vascular prosthesis validation.

At our laboratory, we perform Water Permeability testing in full compliance with ISO 7198, ensuring every device is evaluated under clinically relevant conditions to meet international standards.

Vascular prostheses — synthetic grafts designed to replace or bypass diseased blood vessels — must demonstrate reliable performance under physiological conditions.

One of the critical safety parameters is water entry pressure, which defines the minimum pressure required for fluid to penetrate the graft wall. This property is essential to ensure that the prosthesis prevents leakage during implantation while still supporting tissue integration. That’s why ISO 7198 requires rigorous water entry pressure testing as part of vascular prosthesis validation.

Vascular prostheses — synthetic grafts designed to replace or bypass diseased blood vessels — must demonstrate not only mechanical strength and durability but also controlled integral water permeability. This property defines how much fluid can pass through the graft wall under pressure. Excessive permeability can lead to blood leakage, while insufficient permeability may impair tissue healing and integration. That’s why ISO 7198 requires rigorous integral water permeability testing as part of vascular prosthesis validation

Vascular prostheses — synthetic grafts designed to replace or bypass diseased blood vessels — must provide reliable long-term performance while maintaining blood integrity. One of the most critical safety parameters is permeability, the controlled passage of fluid through the graft wall. Excessive permeability can lead to blood leakage, while insufficient permeability may impair tissue integration. That’s why ISO 7198 requires rigorous permeability testing as part of vascular prosthesis validation.
