HIGH-STRENGTH RESTRAINT STENT OF NON-IMPLANTABLE BALLOON CATHETER AND BLOOD VESSEL EXPANDING DEVICE USING SAME

摘要

Disclosed is a high-strength restraint stent of non-implantable balloon catheter, comprising a main body part (1) for encapsulating the outer part of said balloon catheter, and a fixing part (2) connected to the two ends of said main body part and designed for fixing said connecting balloon catheter, wherein said restraint stent is used for tracking said balloon catheter expansion, or contracting and inhibiting the maximum expanded volume of said balloon catheter. Also disclosed is a non-implantable blood vessel expanding device, comprising said balloon catheter, and said restraint stent having respectively a compression shape for the implantable blood vessel and an expanded shape used for blocking blood vessels. The maximum diameter of said restraint stent in the expanded shape is smaller than the maximum diameter of said balloon catheter in an expanded shape. The invention is simple in structure, convenient to use, greatly improves the treatment efficiency, and reduces the occurrence probability of damage and blood vessel complications.
