US 4,790,829 A · Reusable injection catheter

Abstract

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.
