Connection system for tunneled catheters
First Claim
1. A catheter assembly, comprising:
- a proximal catheter assembly portion including a bifurcating hub, the bifurcating hub including at least one fluid passageway;
a distal catheter assembly portion including a catheter tube defining at least one lumen, the catheter tube including a polymeric material;
a cannula assembly including at least one cannula operably connected with the at least one fluid passageway of the bifurcating hub, the at least one cannula further configured to operably connect with the at least one lumen of the catheter tube so as to provide fluid communication between the proximal catheter assembly portion and the distal catheter assembly portion when the proximal catheter assembly portion and the distal catheter assembly portion are connected; and
a polymeric coating including the polymeric material, the coating included with at least one of the at least one cannula and the catheter tube, the polymeric coating configured to provide a seal between the at least one cannula and the catheter tube when the proximal catheter assembly portion and the distal catheter assembly portion are connected by an interference or slip-type fit.

Abstract
A catheter assembly is disclosed, comprising a proximal catheter assembly portion and a distal catheter assembly portion. The proximal catheter assembly portion includes a bifurcating hub that defines at least one fluid passageway. The distal catheter assembly portion includes a catheter tube that defines at least one lumen and includes a polymeric material. A cannula assembly is also disclosed and includes at least one cannula that is operably connected with the fluid passageway of the birfurcating hub. The cannula is further configured to operably connect with the lumen of the catheter tube so as to provide fluid communication between the proximal and distal catheter assembly portions when the two portions are connected. A polymeric coating is included with the cannula and the catheter tube, and is configured to provide a seal between the cannula and the catheter tube when the proximal and distal catheter assembly portions are connected together.
