ABSTRACT:
A suture anchor is formed of a material which absorbs body liquid when exposed to body liquid. The anchor may be at least partially formed of a material having a strong affinity for body liquids. This enables the anchor to absorb body liquid and expand upon being inserted into a patient's body. At least one embodiment of the suture anchor has portions formed of a relatively hard material which does not absorb body liquids and is pressed against body tissue by the material which absorbs body liquid to mechanically interlock the suture anchor and the body tissue. The anchor may be at least partially formed of a cellular material. The-cells expand to absorb body liquid. At least one embodiment of the anchor has a pointed leading end portion to form an opening in an imperforate surface on body tissue. The configuration of the anchor may be changed by tensioning the suture while the anchor is disposed in body tissue.
