Abstract
This paper describes a method for 3D printing in the body using a coaxial applicator to heat a biopolymer that solidifies when heated. This method is proposed for creating conductive lines in the body for focusing electromagnetic fields on a very small (4 mm on a side) implantable medical device. A 2450 MHz sleeved slot coaxial applicator with a pointed, extended, hollow tip is designed to heat 400 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> of polymer from body temperature to its crosslinking temperature of 40 °C in 10 s.
