The present disclosure is directed to an over-the-needle (OTN) catheter assembly having a structural member configured therein. The OTN catheter assembly includes a catheter coaxially mounted onto a needle. In one embodiment, the structural member includes a coil insert that is embedded into an interior wall of the catheter, thereby preventing kinking of the catheter when being inserted within a patient. In another embodiment, the structural member may be a separate and removable coil insert that is inserted into the catheter after the OTN catheter assembly has been placed in a targeted site within the patient and the needle is removed. In a further embodiment, the structural member may be a separate and removable solid insert having a blunt distal end that is inserted into the catheter after the OTN catheter assembly has been placed in a targeted site within the patient and the needle is removed. Thus, the structural member is capable of advancing the catheter to one or more targeted sites within the patient, if desired, without causing further discomfort to the patient. |
