Abstract
A prosthetic anchor to be attached to a natural or prosthetic structure of a human or animal. The anchor includes a central layer with first and second surface. A plurality of fiber bundles, each with a medial portion, are concentrically embedded within the central layer to substantially define a horseshoe-shaped pattern. A substrate element is configured to be secured to the natural or prosthetic structure and to receive the second surface of the central layer. A securing element operably coupled to the second surface of the central layer is configured to secure the central layer to the substrate element in at least two positions.
Claims15
A prosthetic anchor for attaching to and extending between a first natural tissue and a second natural tissue or prosthetic structure in a subject, comprising;
- a plurality of fiber bundles, each fiber bundle of the plurality of fiber bundles having a medial portion that substantially defines a generally horseshoe-shaped pattern having first and second branches extending from the medial portion, the medial portion being contained within a central layer;
- a first plurality of tension elements extending from the first branch and a second plurality of tension elements extending from the second branch, the first and second plurality of tension elements extending to and operatively connected to a tissue engaging portion, the tissue engaging portion configured to extend through the first natural tissue and to disperse therein with a proliferation of cells;
- a first partial envelope and a second partial envelope positioned adjacent to and spaced away from one another and defining a space therebetween, each of the first and second partial envelopes enclosing at least a portion of the central layer and configured to interface with the second natural tissue or prosthetic structure;
- the first partial envelope surrounding at least a portion of the first branch of the plurality of fiber bundles;
- and
- the second partial envelope surrounding at least a portion of the second branch of the plurality of fiber bundles,
- wherein at least a portion of the medial portion of the plurality of fiber bundles is positioned within the space between the first and second partial envelopes.
