What you see in this picture below is the dressing, with the driveline coming out of it, and going to the bag. This is what attaches the pump inside his chest to the computer and batteries outside, in the bag.
Here, you see the driveline exit wound. He has healed very well and remained infection free for the last 3+ months since having this placed. The driveline is made with some sort of fancy material that allows the skin to actually grow onto it!
And here's the bag that must go everywhere with him. Going to the store to pick up juice? Yes, the bag goes too. It contains backups of all his equipment (controller, batteries, manual, etc.). Won't let me bling this either :p
