Anchoring device with multidirectional, flexible anchoring elements for detachable fixation in recording media

Abstract

(The basic principle) Anchoring device for releasable, form-fitting fixation in a receiving medium, comprising: a) an elongated central body (1) with a proximal and a distal side, b) several flexible, wire- or rod-shaped anchoring elements (2), each having a first end connected to the central body (1) and a second, free end, c) one or more guide elements (3, 4), preferably rings, spaced apart along the longitudinal axis of the central body (1), which at least partially surround the anchoring elements and guide, support or influence their radial orientation, characterized in that d) the anchoring elements (2) between the guide elements (3, 4) and / or distal to the distal guide element (3, 4) are prestressed, preformed or angled such that they preferably emerge from the guide elements (3, 4) at different angles (α, β, γ) deviating from the longitudinal axis and extend in different / multiple directions in the receiving medium, e) at least one of the guide elements (3, 4) has an attack structure (5) selected from the group consisting of or comprising: eyelets, projections, recesses or perforations, wherein the attack structure (5) is designed to accommodate an integrated, semi-integrated or separate release mechanism (8), and f) the anchoring elements (2) have at their free ends an end contour (6) consisting of or comprising the group: - thickened, rounded or spherical heads, - pointed or conical tips, - pointed or sharpened ends, - Combinations thereof, selected, wherein the final contour (6) is designed such that it a) reduces damage to the recording medium, b) facilitates penetration into the receiving medium, c) improves the form fit, or a combination thereof.
