A reusable injection catheter for use with a medication delivery system comprises a flexible conduit having a fluid path therethrough, a first cannula at the distal end of the conduit for insertion into the patient, a connector housing at the proximal end of the conduit having a passageway therethrough, and a second cannula extending from the housing and in fluid communication therewith. An embodiment of the present invention includes a resilient sleeve covering the second cannula to prevent fluid passage therethrough. This sleeve is adapted to be pierced by the second cannula upon the application of force to the sleeve, thus allowing fluid flow through the second cannula, and further adapted to return to its initial position upon termination of the force.

A disposable reservoir cassette for use with a roller pump delivery system comprises a flexible reservoir tube, an air-permeable, liquid-impermeable element engaging one end of the reservoir tube, a pierceable delivery septum engaging the other end of the reservoir tube and a rigid housing containing the reservoir tube. The housing includes a backstop which supports the tube in a circular path while allowing access to the septum. The housing is adapted to be secured to the roller pump such that the circular path of the tube is adjacent to the path of a pump roller wherein motion of the pump roller compresses the reservoir tube sufficiently to drive any fluid contained therein in the direction of the delivery septum.
