Bifurcation stent and the system for intravascular implanting of the bifurcation stent

摘要

The stent for bifurcation 1 is characterized in that it consists of the distal part that has a smaller diameter and of the proximal part - that has a greater diameter, connected with connecting struts to form a cell of the stent of an increased surface area. The system for intravascular implantation of the stent for bifurcation 3 is characterized in that, in the distal part of the system 3, there is a profilled balloon 2 marked with three marker bands 6, 7, 8 located on an internal tube 5 of the system for intravascular implantation of the stent for bifurcation. The profilled balloon 2 consists of three inseparable parts: the distal part - that has a smaller diameter, the proximal part - that has a greater diameter and of the middle part. On the profilled balloon 2, the stent for bifurcation 1 is crimped in a detachable manner, in such a way that the cell of the stent of an increased surface area of a stent for bifurcation 1 coincides with the middle part of the profilled balloon 2.
