The rationale and technic of a new procedure—transluminal recanalization of arterio-sclerotic obstructions—has been described. Of the 11 extremities treated, six have shown marked improvement (four amputations averted). It is reasonable to assume that with a perfected technic and patients with less advanced disease, the percentage of successful recanalizations would increase. Early treatment with this technic may well prevent otherwise serious disease, not just prevent amputation of extremities not suitable for definitive surgery. We are satisfied that percutaneous transluminal recanalization is the treatment of choice for many lesions of the femoral and popliteal arteries. We believe this method is ready for application to obstructions up to approximately 10 cm. by those skilled in the use of vascular catheters. No doubt the interest and ingenuity of others will lead to refinements of technic as well as further clarification of the role of this attack on arteriosclerotic obstructions.

A method is described for the percutaneous catheter placement of expandable nitinol coil stents for the nonoperative restoration and maintenance of patency in internal flow pathways, especially the lumina of blood vessels and biliary ducts.
