An idea on traversing the skin

First my background: 7 years of dialysis tech experience. (Connect people to machines to clean their blood)

So i have been reading the forums and see people wish to have a bio compatible alternative to bridging the gap through the skin. I had an ahh haaa moment and immediately thought of my work.

let me introduce a Subclavian Central venous Catheter to you.

A lot of the patients I have dealt with have had the same catheter in the same place for 10+ years. I am in no way saying there is zero risk here. I am just presenting another option.
 It looks like this on the inside

Pretty much a tube going straight to your heart. Which then blood is pull out of the red port cleaned and push back through the blue port.

They tell us chances of infection are there, but in 7 years with the same people I have yet to see it. People have had serious reactions to the bandage adhesives than the actual catheter.

So I am thinking  this technology could be used with a smallerlength tube to go under your skin to bring things out.

   Interesting. How does this technique have such a low infection rate? I noticed you mentioned that bandage causes issues. Is the bandage used as a seal against things?

   
   

   What material is the tube made of? I'm assuming PVC for this particular type of application...

   
   

   Any more information would be appreciated.

   Cites complications in up to 15%, infectious in 5-26%. 

   
   

   It's probably lower due to the regular inspection of the site and professional nature of the procedure; dialysis clinics don't generally mess around much.

   Yeah, I've thought about this type of an option as well. PICC lines and central venous catheters use a similar material. The reason I haven't pursued this type of a route is all the prohibitions that go with it. For example, I like to swim. Another pre-existing product I think would be better is a portacath or some similar variant. Rather than always being accessed, they are accessed as needed via a huber needle. If we made unit that ran off of a less than toxic fluid such as glucose or something, it could serve as a "fuel resevoir" that could be topped off as needed.
