Abstract
A method and an apparatus for making tube bundles for various medical applications such as oxygenators, dialyzers, and heat exchangers is described. The tube bundle is suitable for use as a heat exchanger in, for example, a blood cardioplegia circuit. The winding apparatus axially winds a flexible tube around a winding core. The apparatus includes a tube shuttle, a shuttle driver and a core driver. The core driver rotates the winding core to distribute the tube on the winding core in layers.
