Abstract
A closed-ended catheter assembly that includes an electrically conductive pathway is disclosed. The conductive pathway enables electrical signals, such as ECG signals produced by a patient's heart, to pass through the closed-ended tip of the indwelling catheter while still preventing unintended fluid flow. In one embodiment, therefore, a catheter assembly is disclosed and comprises an elongate catheter tube including a closed distal end. The catheter tube defines at least one lumen and includes a valve defined in the catheter tube that is configured to selectively enable fluids to pass therethrough. The catheter tube includes a conductive element that provides an electrically conductive pathway between the at least one lumen and an exterior portion of the catheter. The conductive element includes a porous material extending between the at least one lumen and the exterior portion of the catheter, the porous material being transmissive to electrical signals and non-permeable to blood.
