Endoprosthesis for the treatment of blood-vessel bifurcation stenosis and purpose-built installation device
First Claim
1. An endoprosthesis for the treatment of blood-vessel bifurcation stenosis, comprising three tubular sections and two articulation connectors namely:
- a proximal section;
a first distal section aligned at least approximately with the proximal section and intended for insertion into a first blood vessel branching off from the bifurcation, the first distal section being linked to the proximal section by a lateral first connector; and
a second distal section located at the side of the first distal section and intended for insertion into a second blood vessel branching off from the bifurcation, both distal sections having their proximal ends linked by a second connector which allows relative pivoting of said distal sections about said second connector to accommodate the blood-vessel bifurcation, wherein the distal end of the proximal section is chamfered and the proximal end of the second distal section is tapered at the other side of the second connector and able to fit into the chamfered form of the proximal section.

Abstract
An endoprosthesis for the treatment of blood-vessel bifurcation stenosis. The endoprosthesis comprises three tubular sections (110, 120 and 140) and two connectors (130 and 150). A distal section (120) is aligned at least approximately with a proximal section (110). The first distal section is intended for insertion into a first blood vessel (T2) branching off on the bifurcation. The first distal section (120) is linked to the proximal section (110) by a first lateral connector (130). A second distal section (140), located at the side of the first distal section (120) is intended for insertion into a second vessel (T3) branching off from the bifurcation. The two distal sections (120 and 140) have their proximal ends linked by a second connector (150).

21. An endoprosthesis for the treatment of blood-vessel bifurcation stenosis, comprising three tubular sections and two articulation connectors namely:
-
a proximal section;
a first distal section aligned at least approximately with the proximal section and intended for insertion into a first blood vessel branching off from the bifurcation, the distal section being linked to the proximal section by a lateral first connector; and
a second distal section located at the side of the first distal section and intended for insertion into a second blood vessel branching off from the bifurcation, both distal sections having their proximal ends linked by a second connector which allows relative pivotment of said distal sections about said second connector to accommodate the blood-vessel bifurcation wherein the second connector has at its centre a plane of symmetry determined by the axes of the tubular sections and extends in a direction approximately perpendicular to these axes and wherein the distal end of the proximal section is chamfered and the proximal end of the second distal section is tapered at the other side of the second connector and able to fit into the chamfered form of the proximal section. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
