KENSEY NASH CORP. Exton, Pennsylvania; A Lesson In How One Product Means A Lot.(THE NEW AMERICA)

Byline: GLORIA LAU

Kensey Nash might sound like the name of a country singer in the South, but it's actually a medical firm based outside Philadelphia.

Still, like a lot of country singers, the company knows a thing or two about aching hearts.

Kensey designed and developed the Angio-Seal, a device that lets cardiologists quickly seal up holes they pierce in femoral arteries during certain medical procedures, including angioplasty to unclog heart vessels.

"Their Angio-Seal business is going extremely well," said analyst James Terwilliger of Morgan Keegan. "If you look at the last three to four quarters, that business has increased 40% to 60% year over year, and it's gaining market share in an expanding market."

After angioplasty is finished, doctors must seal the puncture they made to the femoral artery. They use the Angio-Seal in combination with a collagen plug and anchor that are also made by Kensey.

The anchor is placed inside the blood vessel and locks itself against the vessel's inner wall. The plug is deposited right on top from the vessel's exterior. The whole process takes a minute.
