AORTIC BARE STENT AND AORTIC DISSECTION STENT
First Claim
1. An aortic bare stent, in a tubular net structure, comprising:
- a plurality of support stents in circles, wherein the plurality of support stents are arranged along an axial direction; and
a plurality of connector stents, wherein each of the plurality of connector stents is operable to connect two adjacent support stents of the plurality of support stents, each of the plurality of connector stents is made of a hyper-elastic material, and a flexural rigidity of each of the plurality of connector stents is less than that of each of the plurality of support stents.

Abstract
An aortic bare stent and an aortic dissection stent are disclosed. The aortic bare stent is in a tubular net structure, with multiple support stents in circles and arranged along an axial direction. Two adjacent support stents are connected by a connector stent. The connector stent is made of a hyper-elastic material. A flexural rigidity of the connector stent is less than that of the support stent. The support stent is made of a single-strand hyper-elastic nickel titanium wire or formed by cutting a nickel titanium tubing. The connector stent is made of a multi-strand composite wire. The multi-strand composite wire is formed by twisting or weaving multiple strands of filaments, and each strand of filament is independently of a nickel titanium material.
