New Access Device for Angiographic Procedures

The device is deployed seamlessly at the beginning of the arstaotomy procedure, creating a shallow-angle needle pathway through the wall of the femoral artery to provide access to the vasculature. This longer and shallower angle results in significant tissue-upon-tissue overlap, which collapses from the normal pressure of the patient's femoral artery blood flow from below upon withdrawal.

Thus, only brief manual compression is needed at the end of the procedure to close the access site; within seconds, the normal intra-arterial pressure works together with the manual compression to seal the access site naturally, without the need for a closure device implant. Patients can sit up and walk sooner, and experience a more comfortable recovery. The Arstasisone Access Device, a product of Arstasis (Redwood City, CA, USA) thus provides an effective alternative to standard arteriotomies and vascular closure implants. The device has been approved by the US Food and Drug Administration (FDA).

"We are delighted to begin providing US cardiologists with a femoral artery access device that allows them to perform angiography without resorting to inserting a vascular closure implant into the patient,” said Bruce Modesitt, CEO of Arstasis.

Since 1959, physicians have been using the Modified Seldinger Technique to insert flexible catheters into the femoral artery of patients for performing procedures in the patient's arterial-vascular system. The most prevalent such procedure, diagnostic angiography, is thought to be performed more than 500,000 times per month worldwide. At the end of every such case, the patient is left with a substantial hole in the femoral artery, which typically takes significant effort and catheterization laboratory resources to close.
