A method of forming a loop in a thread is provided. The method includes the steps of providing a loop forming system including, a base for securely retaining a thread to be formed and a welding assembly for forming a loop in the thread, contacting at least a portion of the thread with a super-critical fluid and securing the previously immersed portion of the thread to the base such that a first section of the previously immersed portion is maintained adjacent to a second section of the previously immersed portion. The method further includes the steps of approximating the welding assembly and the base towards each other, and approximating the welding assembly and base away from each other. Also provided is a medical device formed from the method.
