Abstract
The present invention relates to a method and apparatus used to place a catheter having a distal end and a proximal end where the proximal end cannot be trimmed within a patient. The method and apparatus utilize a device operative in locating the tip of a catheter, which includes a detector assembly having a detector and a locator. The detector of the detector assembly is locked into positioned remote from the distal end of the catheter prior to inserting the catheter in the patient. The distal end of the catheter is trimmed, as to define a trimmed distal end, the detector is then unlocked and placed proximate the trimmed end. In the preferred embodiment the detector is locked into place proximate the trimmed distal end and the catheter is placed within the patient.
