Delivery tubes having a flexible portion and pump mechanisms (4) for use therewith include features that reduce losses of an active therapeutic compound within a fluid passing through the delivery tube (17). The delivery tube can include inner (30) and outer (31) layers that are inert to reaction with the therapeutic compound and that restrict diffusion of other compounds, respectively. Rollers (83) of a peristaltic pump mechanism (80) can include structural features that reduce physical impacts on molecules of the therapeutic compound. Related systems, apparatus, and/or articles are also described.
