We have previously reported that seamless woven tubes of nylon or Teflon (a plastic consisting of tetrafluoroethylene polymer), 7-10 mm. in diameter and 18-24 cm. in length, function well as experimental arterial substitutes in anatomical locations where they are not subjected to bending stress.¹ When bent, these tubes buckle and show a high incidence of wrinkle thrombosis. Since it appeared that a prosthesis with elastic qualities would overcome this deficiency, our attention was turned to a prosthesis composed partly of an elastic nylon yarn.

Materials and Method

Characteristics of the Prosthesis.

—The prosthesis used is woven with an ordinary tubular weave as a seamless tube and is made up of two types of nylon yarn. A magnified view of this material is shown in Figure 1. The longitudinal fibers are so-called "Helanca" nylon, and the circular fibers are plain, straight nylon. Table 1 gives the details of the weave, . . . [Full Text PDF of this Article]
