Anchor

Abstract

An anchor for insertion into an aperture, wherein the anchor includes a body element, two or more elongate engagement members, and a release element. The body element has a first end and an opposed second end, and the body element defines a tapered surface adjacent to a first end portion of the body element. The release element is slidably coupled to the body element. Each of the engagement members has a first end via which the engagement member is coupled to the release element, and a second end which includes a radially outwardly projecting lug. The second ends of the engagement members engage the tapered surface defined by the body element. When the release element is in a release position relative to the body element, the second ends of the engagement members are engaged with a relatively narrow portion of the tapered surface and the lugs are in a radially contracted configuration. When the release element is in an engaged position relative to the body portion, the second ends of the engagement members are engaged with a relatively wide portion of the tapered surface and the lugs are urged radially outwards from the body element by the tapered surface to form a radially expanded configuration.
