Abstract: Tunneling systems and methods or making and using such systems for implanting biological devices, especially catheters, are described. The tunneling system of the invention contains flexible connection tunnelers that contain multiple connection features that are of dissimilar lengths. When used for a multiple lumen catheter, the connection features are easier to separate and are easier to connect with the lumens of the catheter that are in different positions relative to the tunneler. Thus, the tunneling system contains a non-destructive connection between the catheter tip and the tunneler, as well as allowing for greater control during placement of the catheter.

Abstract: A hose clamp identification marker for selectively identifying contents of a flexible hose. The hose clamp identification marker may be implemented in connection with a hose clamp and may comprise an open channel configured to straddle a hose. In this manner, the hose clamp identification marker of the present invention may be introduced to and removed from the hose clamp without disrupting continuity of treatment or requiring disassembly of the connection between the hose and a delivery device, such as a hollow needle.
