Abstract:
A surgical anchor for securement into an organic medium comprising:a first generally hollow cylindrical member having a plurality of longitudinally extending engaging fingers;a second generally hollow cylindrical member having a plurality of longitudinally extending engaging fingers, the fingers of said first member and said second member opposing each other and being interdigitated, there being provided cam surfaces on each member for engaging with fingers of the opposed member;a central longitudinally extending shaft disposed concentrically in said first and second members, the shaft having an abutment at a distal end abutting against the first of said members and having an engaging surface at a proximal end for engagement by an emplacement tool for emplacing the anchor into the organic medium;the members moving longitudinally relatively towards each other during emplacement of the anchor, the longitudinally extending fingers of each member abutting against the cam surface of the opposed member thereby causing the longitudinally extending fingers to move radially outwardly as the two members move relatively towards each other, the fingers of each member thereby penetrating into the organic medium to secure the anchor in position in the organic medium;and further wherein the fingers of one member are of a different length than the fingers of the other opposed member, thereby causing the fingers of the one member having a longer length to begin engaging in the organic medium prior to the fingers of the other member.
