Abstract

A detachable catheter apparatus that conveys a fluid includes a tube assembly and an insertion device. The tube assembly extends along a longitudinal axis and includes a distal tube section having a closed end and an opposite opened end, a proximal tube section having a first end and an opposite second end and a connector fabricated from a flexible, deformable material. The connector connects the opened end of the distal tube section and the first end of the proximal tube section together. The distal tube section includes an orifice formed therethrough and sized to enable fluid to enter the distal tube section so that the fluid can flow into and through the distal tube section, the connector and the proximal tube section. The insertion device is slidably receivable by the tube assembly, and includes an elongated inner alignment rod having a contact end portion and an insertion end portion disposed opposite the contact end portion. The inner alignment rod is sized to extend into the tube assembly so that the contact end portion contacts the closed end of the distal tube section while the insertion end portion projects outwardly from the tube assembly.
