Abstract
The controlled first-order release of either an antithrombotic or thrombolytic agent from a sutures at an anastomosis site is disclosed which prevents postoperative thrombosis and improves vascular patency in animals. A suitable polymer, such as polycaprolactone, is blended with prostacyclin or analogues of prostacyclin to form the suture material.
