CATHETER COUPLER AND METHODS OF EXCHANGING CATHETERS

Abstract:

The present disclosure relates to a catheter coupler and methods of exchanging catheters within a patient with a replacement catheter. The catheter coupler is configured to couple to a first catheter that has been disposed within a patient and coupled to a second or replacement catheter. Once the coupler is coupled to the first and second catheter, the first catheter may be withdrawn from the patient, which simultaneously advances the second or replacement catheter into the previous position of the first catheter. The coupler may include a body with a first end and a second end. The coupler may have a plurality of barbs disposed on both ends of the body of the coupler, wherein the barbs are configured to couple the coupler to the lumen of the catheters.
