    Abstract: The invention provides a flexible plastic formulation capable of being extruded, blow-molded, ethylene oxide and radiation sterilized. The plastic formulation of the invention comprises: a) from about 60 to about 94 percent by weight of a copolymer consisting essentially of ethylene and vinyl acetate units; b) from about 5 to about 25 percent by weight of a block copolymer, the block copolymer consisting essentially of a central block copolymer molecule including generally equal proportions of ethylene and butylene units, and terminal blocks of polystyrene; and c) from about 1 to about 15 percent by weight of an ultra-low density polyethylene material. The plastic formulations of the invention are useful in the manufacture of blood bags, tubing and the like.

    Abstract: An umbilicus (24) conveys fluid between a stationary body and a rotating body in a small, compact operating environment. The umbilicus comprises an elongated body (200) including a proximal end, a distal end, and a middle region between the proximal and distal ends. A first support block (204) is attached to the proximal end. A second support block (206) is attached to the distal end. The first support block (204) includes a strain relief sleeve (212). The umbilicus is otherwise free of any other strain relief sleeve. A thrust bearing member (214) in the middle region spaced apart from the strain relief sleeve (212) and the distal end. The umbilicus is otherwise free of any other thrust bearing member. The thrust bearing member (214) has an inner annular body (218), an outer annular body (216) about the inner annular body (218), and an array of ball bearings (220) between the inner and outer annular bodies. The ball bearings (220) support the inner annular body (218) for rotation relative to the outer annular body (216).
