erties of double-layered scaffolds. (A) Scaffolds (a) were extended at 250%
of initial length (b) with 3MPa for 5 sec and recovered (c) by releasing the
load. Scaffolds were twisted (d) and folded (e) as through testing via a ten-
sile system clamp. (B) Suture retention strength of double-layered scaffold,
ePTFE, and canine abdominal aorta.

(Fig. 27.4A-c) after 250% extension (Fig. 27.4A-b) of the initial
length (Fig. 27.4A-a) for 5 sec. The PLCL scaffolds were easily
twisted (Fig. 27.4A-d) and folded (Fig. 27.4A-e). The suture reten-
tion strength of the scaffold was measured to be 7.68 ± 0.75 N
( n = 5), as shown in (Fig. 27.4B), compared with the strengths of
ePTFE (8.82

±

0.99 N) and canine abdominal aorta (10.04

±

0.60 N).

The burst pressures were more than 900 mmHg.
