Patent attributes
In a vascular anchoring device intended to be introduced into a blood vessel by a catheter and including braces (2) that are expandable in the radial direction, the anchoring device is formed by a substantially hollow-cylindrical part (1) including axially extending braces (2) departing from an end side, and a locking member (3) coaxially guided within the hollow-cylindrical part (1) along a guide wire (4) of the catheter. The locking member (3) carries at least one ramp surface (9) on its end facing the braces (2), which ramp surface causes the braces (2) to expand by an axial displacement relative to the braces (2), and at least one stop (10) cooperating with the hollow-cylindrical part (1) in the expanded position. The guide wire (4) carries a further stop (7) which cooperates with a counter stop surface (8) of the locking member (3), upon displacement of the guide wire (4).
