Patent ID: 11819645

Abstract:
Representative embodiments of a catheter, e.g., a dialysis catheter, and a method of use of the catheter, are disclosed. A representative catheter includes a catheter body and a balloon coupled to the catheter body. The catheter body includes first, second, and third ports, with the second port arranged spaced apart longitudinally from the first port; and first, second, and third lumens, the first lumen in fluid communication with the first port, the second lumen in fluid communication with the second port, and the third lumen in fluid communication with the third port. The balloon is arranged between the first and second ports, and is coupled to the third port. The balloon is inflatable using a fluid injected through a connecting tube and into the third lumen, helping to remove any fibrin sheath which may have formed around the first and second ports, and diminish recirculation of blood during dialysis.
