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.

Method and apparatus for manufacturing wound tube bundles

An apparatus and a method for making a transfer device comprising a tube bundle. The transfer device is suitable for use as a heat exchanger in a blood cardioplegia circuit, for example. The apparatus axially winds a flexible tube around a winding core. The apparatus includes a winding core, a core rotating means, a tube bobbin, and a tube shuttle to guide the tube around the core. A shuttle rotating means rotates the tube shuttle around the core. The method of making the transfer device includes providing a winding core, winding a tube from end to end around the winding core, fitting the wound bundle into a housing, sealing the first and second ends of the housing using a potting material, cutting the ends of the bundle to expose a lumen within the tubes, and attaching a first end cap and a second end cap.
