Abstract

An improved side slit catheter is provided for use in long term delivery of a selected medication to a patient, wherein the catheter has a distal end tip shaped to permit expulsion of an occlusive deposit. The catheter includes an elongated lumen for passage of medication such as insulin to the distal end tip for administration to the patient at a selected infusion site. The tip includes a cylindrical wall segment defining a tapered bore which expands in cross section to a delivery port, with at least one and preferably a plurality of longitudinal side slits formed in said wall segment. In the event of delivery port occlusion, medication delivery at normal pressure will continue through the side slits. The occlusion can be expelled from the catheter tip by delivering a selected fluid through the catheter at elevated pressure, whereupon the slitted catheter tip deformably responds to detach from and thus permit expulsion of the occlusion.
