1. A system for placement of biocompatible electrodes in an opening formed in a patient's body part, comprising:
a catheter including a guide tube, the guide tube having a longitudinal axis and at least three guide elements extending along the longitudinal axis;
each of the guide elements including a first end, a second end, a plurality of rotatably-connected segments extending between the first and second ends, and a plurality of joints connecting adjacent ones of the segments;
the guide elements being configured to releasably fit together and collectively form a continuous lumen through the catheter, the lumen extending along the longitudinal axis of the guide tube and being dimensioned to receive an electrode therein;
an annulus including a circumferential rim defining an interior circular space that is dimensioned to receive the catheter therethrough, and a number of legs engaging the rim and extending outwardly therefrom, the annulus being configured to be secured in the opening;
and means for operably coupling the catheter to the annulus.
