FIG. 1.

Electrospun poly(ɛ-caprolactone) (PCL) conduits exhibit a range of average fiber diameters. Shown are scanning electron microscopy images of meshes electrospun from solutions containing 14.5% w/v (A, D), 17% w/v (B, E), and 22% w/v (C, F) of PCL. Images (A–C) are of the outer surface and images (D–F) are of the luminal surface of the conduits. An arrow indicates the average direction of fiber orientation. These constructs were included within poly(tetrafluoroethylene) (PTFE) pouches with either larger (G) or smaller (H) pores to allow peritoneal cells and fluid to penetrate.
