Figure 1 Features of PEUU and Representative Images, at 8 Weeks After Implantation
Electron micrograph of the polyester urethane urea (PEUU) material (A). Polyester urethane urea patch in final format (6-mm diameter x 300 µm thick) (B). Representative images, 8 weeks after implantation, of the anterior view of infarction control (C) and PEUU patched (D) hearts. The cross-sectional view of both groups is shown in E and F, respectively. Black arrows point to the implanted PEUU patch, and white arrows indicate the infarcted anterior wall. Scale bar: 500 µm in A, 1 mm in B, 55 mm in C to F. P = the patch implanted area; S = the infarcted scar.
