Catheter having improved traceability
Embodiments hereof relate to a catheter having a metal hypotube proximal shaft and a radio frequency identification (RFID) integrated circuit electrically connected to the metal hypotube such that the metal hypotube operates as an antenna for transmitting and receiving modulated RF signals between the RFID integrated circuit and an external receiver configured to read the electronic identification information carried by the RFID integrated circuit. The hypotube and RFID integrated circuit are embedded in a luer hub of the catheter. The RFID integrated circuit contains electronic identification information such as model/serial number, manufacturing information and other summary information for improving traceability of the catheter and removing paper work associated with product tracking.
1. A catheter comprising:
an elongate catheter shaft having a proximal metal hypotube;
a luer hub positioned over at least a portion of the metal hypotube; and
a RFID integrated circuit embedded within the luer hub and electrically connected to the metal hypotube such that the metal hypotube operates as an antenna to transmit and receive modulated RF signals between the RFID integrated circuit and an external receiver configured to read electronic information carried by the RFID integrated circuit.
2. The catheter of claim 1 , wherein the hub is overmolded onto the at least a portion of the metal hypotube and includes a hub body having a lumen extending therethrough that is fluidly connected to a lumen of the elongate catheter shaft.
3. The catheter of claim 1 , wherein the electronic information carried by the RFID integrated circuit is selected from the group consisting of product name, serial number, product part number, manufacturing information, lot history, length of the catheter, outer diameter of the catheter, devices currently compatible with the catheter, product recall information, warning information, or instructions for use.
4. The catheter of claim 1 , wherein the metal hypotube is operable to receive RF energy from the external reader to permit external powering of the RFID integrated circuit.
5. The catheter of claim 1 , wherein the metal hypotube is made of stainless steel 304.
6. The catheter of claim 1 , wherein the RFID integrated circuit is electrically connected to the metal hypotube via two interconnections.
7. The catheter of claim 6 , wherein the interconnections are made by laserwelding the RFID integrated circuit to the metal hypotube.
8. The catheter of claim 1 , wherein the hypotube includes a helical cut formed therein.
