Vascular Medical Device, System And Method

Abstract

The present application discloses a covered stent and a method for navigating the covered stent to a branch vessel, the covered stent including a main body and at least one lateral side branch connected to the main body. A system of covered stents and a method for implanting, including interconnecting the covered stents is also disclosed.

What is claimed is: 
     
         1 . A covered stent comprising a lateral side branch extending from a main body of the stent, 
 a supporting frame in the lateral side branch, the supporting frame having a frame pattern with an asymmetrical design for improved collapsibility of the stent.   
     
     
         2 . The covered stent of  claim 1 , wherein the frame is made of nitinol. 
     
     
         3 . The covered stent of  claim 1 , wherein the frame is a laser cut structure. 
     
     
         4 . The covered stent of  claim 1 , wherein the pattern has a region without a supporting frame. 
     
     
         5 . The covered stent of  claim 1 , wherein the side branch comprises a connection section configured to provide a degree of movement of the side branch. 
     
     
         6 . The covered stent of  claim 1 , wherein the side branch comprises a connection point configured to connect a connecting element. 
     
     
         7 . A covered stent comprising a lateral side branch extending from a main body of the stent, a supporting frame in the lateral side branch, the supporting frame having a frame pattern of two halves such that the branch is collapsible in a middle region. 
     
     
         8 . The covered stent of  claim 7 , wherein the frame is made of nitinol. 
     
     
         9 . The covered stent of  claim 7 , wherein the frame is a laser cut structure. 
     
     
         10 . The covered stent of  claim 7 , wherein the pattern has a region without a supporting frame. 
     
     
         11 . The covered stent of  claim 7 , wherein the side branch comprises a connection section configured to provide a degree of movement of the side branch. 
     
     
         12 . The covered stent of  claim 7 , wherein the side branch comprises a connection point configured to connect a connecting element. 
     
     
         13 . A covered stent comprising a lateral side branch extending from a main body of the stent,
 a supporting frame in the lateral side branch,   the stent having a region without a supporting frame.   
     
     
         14 . The covered stent of  claim 13 , wherein the frame is made of nitinol. 
     
     
         15 . The covered stent of  claim 13 , wherein the frame is a laser cut structure. 
     
     
         16 . The covered stent of  claim 13 , wherein the pattern has a region without a supporting frame. 
     
     
         17 . The covered stent of  claim 13 , wherein the side branch comprises a connection section configured to provide a degree of movement of the side branch. 
     
     
         18 . The covered stent of  claim 13 , wherein the side branch comprises a connection point configured to connect a connecting element.
