1. A medical anchor for securement into a bore formed in a living body and defined by a bore side wall and an opening into the bore, comprising:

  • a first generally hollow biocompatible section having a first plurality of spaced longitudinally directed fingers pointed toward the opening;

    a second generally hollow biocompatible section having a second plurality of spaced longitudinally directed fingers;

    the first and second sections being arranged opposed to each other with the fingers of each section being interdigitated with the fingers of the other section;

    an elongated body mechanically engaged with the first section;

    the first and second sections being adapted to receive a compression force moving the two sections relatively toward each other, the first and second hollow sections having a combined longitudinal size such that they are entirely received within the bore after the compression force is applied, said two sections being both longitudinally movable in respective opposed directions of movement with the fingers of each section moving radially outwardly while moving in the respective direction of movement, the fingers of each section being adapted to penetrate into the bore side wall in the respective direction of movement to secure the two sections in the bore without anchoring the elongated body at the opening into the bore;

    at least one of the first and second sections being slidable along the elongated body without relative rotational movement of the elongated body and the at least one section.
