Abstract

A catheter includes a proximal portion designed for residing externally of a patient vasculature and a distal portion having a distal tip designed for placement in a desired position within the patient vasculature. A storage component is embedded in a portion of the catheter, the storage component including a radio-frequency identification (RFID) chip. The RFID chip includes non-volatile memory that is programmable by a RFID encoder. The storage component includes data related to the placement of the distal tip of the catheter in the desired position within the patient vasculature.

Claims

1. A catheter, comprising:

a proximal portion designed for residing externally of a patient vasculature;

a distal portion having a distal tip designed for placement in a desired position within the patient vasculature;

a storage component embedded in a portion of the catheter, comprising a radio-frequency identification (RFID) chip, the RFID chip including non-volatile memory that is programmable by a RFID encoder, the storage component including data indicating location of a final placement of the distal tip in the desired position within the patient vasculature.

2. The catheter according to claim 1, wherein the catheter includes a bifurcation portion, and wherein the storage component is embedded in the bifurcation portion of the catheter.

3. The catheter according to claim 1, further comprising trimming of the catheter, and wherein the data indicating location of the final placement further includes data selected from the group consisting of a date of the final placement, a final length of the catheter after trimming, and patient creatine or other blood counts.

4. The catheter according to claim 1, wherein the catheter is a peripherally inserted central catheter (PICC) and the data indicating location of the final placement further includes a length of a proximal portion of the PICC after placement is complete.

5. The catheter according to claim 1, wherein the data indicating location of the final placement further includes a first ECG signal profile relating to a position of the distal tip in the desired position at a time of initial placement.

6. The catheter according to claim 1, further comprising a power injection procedure, wherein the storage component further includes data comprising a record of power injection procedures for the patient.
