TriVascular CustomSeal for Ovation AAA Stent Grafts FDA Approved

ovation-prime

TriVascular Technologies (Santa Rosa, CA) won FDA approval for the CustomSeal Technology that’s used in placing the company’s Ovation stent grafts to treat abdominal aortic aneurysms (AAA). The special polymer O-ring on the neck of the stent sits within the aorta, but does not apply continuous pressure against the vessel’s walls to maintain a leak-proof seal.

In order to achieve this, after the delivery of the main part of the stent the O-ring is filled with a polymer to match the patient’s aorta. Once cured, a process that’s now 30% faster that’s to the customized polymer delivery, the rest of the stent graft can be deployed.
