Abstract: A stent having assistant extension portion includes a plurality of ring layers, connecting layer, and assistant extension portion. Each ring layer has a plurality of first crowns connected to each other. The connecting layer has the first crown and a second crown connected to each other. The connecting layer and the ring layers are connected to each other to form a stent body, and the connecting layer is located at one end of the stent body. The assistant extension portion has a fixed end and a free end, the fixed end of the assistant extension portion is connected to the second crown, and the free end of the assistant extension portion has at least one hole.

Abstract: The present invention discloses a molding system, more particularly, a shrinking type molding system comprising an outer mold, an inner mold and a first pattern layer. An adjustable gap is formed between the outer mold and the inner mold to contain a work piece therein. Furthermore, the work piece with a pattern structure on the surface thereof can be formed by the first pattern layer. The difference between the present invention and the prior art is that the molding system of the present invention is capable of optionally or simultaneously forming the pattern structure on the inner surface or the outer surface of the work piece, so as to solve the long last problem that not all the surfaces of the work piece could have the pattern structure thereon in the prior art.

Abstract: The present invention discloses a gas assisted imprint system and the manufacturing method thereof. More specifically, instead of utilizing a rigid platform to, the gas assisted imprint system and the manufacturing method of the present invention utilizes a film to support the work-piece so as to evenly apply a force to the surface by the deformation caused by pressurized gas. More specifically, one of the main features of the present invention is that the present invention utilizes two films to cover the surfaces of a work-piece and applies a force evenly thereto by deforming the films by high pressure fluid. Accordingly, the present invention is capable of pressing the irregular surface of the work-piece evenly, solving the long lasted problem of the prior art.
