Abstract
A method of manufacturing a bundled mat construction for an extracorporeal blood circuit heat exchanger includes attaching a leading edge of a first capillary tube mat segment to a first side of a mandrel. A leading edge of a second capillary tube mat segment is attached to a second side of the mandrel. The first side is diametrically opposite the second side. The mandrel is rolled relative to the mat segments to generate a bundled mat construction. Radial layers of the bundled mat construction are symmetrical relative to a central axis of the mandrel.
