Abstract: A catheter for use in delivery or withdrawal of a formulation, wherein the catheter has an outer layer comprising a bio-compatible material and a barrier layer comprising a material that provides a more effective barrier than the outer layer against inward and outward diffusion of substances that may cause destabilization of the formulation. The outer surface of the barrier layer contacts at least a portion of the inner surface of the outer layer. The catheter may include a flared distal end tip to aid in the release, during a bolus delivery or catheter flush, of any obstruction situated at the distal end tip of the catheter. The larger cross-sectional area at the flared distal end tip minimizes the chances that any obstruction that develops at the distal end tip will be sufficient to hinder the flow of the formulation within the lumen of the catheter.

Abstract: Techniques are described for improved line and clarity of sight for a freezer bank having multiple individual freezers. By selective angling of walls of the freezers, individual doors and the products behind those doors for two or more freezers can be more clearly seen with reduced glare. With this arrangement, more freezer doors can be as clearly seen as typical for product doors at an end of a row or an end of an aisle thereby improving the overall merchantability of a store's freezer section. Applications to a warehousing store environment are described in detail.
