The invention relates to a catheter and a method of placing a catheter that includes a substantially tubular body portion having an outside diameter no less than the inside diameter of an opening in a catheter introducer adapted to insert a portion of the catheter into a patient's body. The catheter also includes a transition member portion adjacent to a first end of the tubular body portion. The transition member portion has an outside diameter that is less than the outside diameter of the tubular body portion and less than the inside diameter of the opening in the catheter introducer. The invention contemplates that the transition member can be coupled to the end of the tubular body portion, integrally formed with the body portion, or extends from the end of body portion and be removable from a distal end of the body portion. A benefit of the catheter including a transition member portion having an outside diameter that is less than the inside diameter of the opening in the catheter introducer is that it allows a means for inserting a through the introducer catheter which is larger than the inside diameter of the introducer. This provides the benefit of OTN insertion with regard to needle size, but allows for a larger catheter to be placed in the vein by the subsequent removal of the introducer once the transition member portion is placed in the vein.
