Abstract
An anchor and method for securement into a bore in a medium. The anchor has a first generally hollow cylindrical section having a first plurality of spaced longitudinally directed fingers and a second generally hollow cylindrical section having a second plurality of spaced longitudinally directed fingers. The first and second sections are arranged opposed to each other with the fingers of each section being interdigitated with the fingers of the other section. The first and second sections are adapted to receive a compression force moving the two sections relatively toward each other, whereby at least some of the fingers move outwardly so as to secure the two sections in the bore in the medium.
