The invention is a medical device intended to close defects in the cribriform fascia/fascia lata/femoral sheath after the introduction of an access sheath to the femoral artery for trans-catheter procedures in interventional cardiology e.g. Transcatheter Aortic Valve Replacement (TAVR) and Endovascular Aneurysm Repair (EVAR). The invention induces tissue closure in such a way as to induce hemostasis of the underlying femoral artery following procedures that require large-bore femoral access, with an outcome of reducing the invasiveness of femoral artery access closure as well as reducing the length of a hospital stay following these procedures, which increases patient comfort and reduces direct costs to the hospital.

Stanford researchers have designed a non-arterial contact medical device that deploys a fascial suture for large bore femoral access closure. Large bore femoral access is becoming more common as surgical procedures evolve from open surgery to endovascular procedures, especially in interventional cardiology and vascular surgery. This new device adapts the fascia suture technique for use in a percutaneous fashion, which reduces invasiveness, decreases complications associated with the use of existing solutions for large-bore arteriotomy closure, and increases post-procedural patient comfort. In addition, this device is effective even in diseased and calcified vessels, a major factor in the failure of current closure technology.
