Idea; Need Help with Coding/Development

Hello I have an idea for a 2D game in unity. It is a simulator of Interventional Radiological procedures. Heres some background:

(This is a simulator available to hospitals for training purposes). I'd like the simulator to be controlled using mouse and keyboard to advance, move, and deploy interventional tools. I need help coding/creating catheters, guide wires, and general selection of them into the game. Also, how can I make a track that the wires may follow (reflective of the arteries and veins of the human body). Any help is appreciated, at the very least I need help with coding the wires and catheters and being able to move them as a character.
