Abstract
A medication discharge assembly useful in patient systems includes a tubular element and a stylet. In a first, closed position, the stylet is seated within the tubular element and may provide a piercing point facilitating insertion of the tubular element to a treatment site. In a second, open position, the stylet is removed from the tubular element, and the tubular element provides a travel pathway for a drug introduced to the tubular element at a proximal connection port for specific interstitial and subcutaneous diffusion and dispersion of medication along the tubular element's length near a distal discharge port through disparate perforations, which may be formed as striations of increasing length nearer the distal discharge port. The stylet in the first position may be oriented to seal this travel pathway. Depth-finding features associated with the tubular element, visually perceptible and particularly useful for placement of the assembly, may be included.
