The invention discloses a method for plastic tube and membrane cutting method bifurcated stent, the coated pipe comprises a main body with at least one branch pipe and coated pipe, in which between the main pipe and the branch pipe is coated with a tapered transition film tube. A piece of rectangular film according to the preset bifurcated stent covered main pipe and the branch pipe size film cut the main and branch film mulching, film mulching and film will be the main branch of transition edge cut bevel, respectively the main film and film branch folded suture after the tapered transition film tube. The existence of the conical transition film tube improves the machinability of the plastic film with large diameter difference between the main film covered pipe and the branch covered pipe, and makes the shape of the coated stent well.
