An implantable adjustable body tissue cuff, apparatus and method. The cuff is an elastomeric strap of biocompatible non-conductive material. The straps tail and head provide adjustable length fastening by a) the tail being formed with longitudinally spaced, laterally paired locking projections and the head being formed with one or more locking apertures or b) the tail being formed with longitudinally spaced locking apertures and the head being formed with one or more laterally paired locking projections. The locking projection shape allows for passage through the locking aperture, while restricting movement in a reverse direction. The cuff accommodates devices such as tissue stimulators or recorders, with conductive elements attached, imbedded, or printed on the strap body. The cuff is intra-operatively adjusted to optimize placement and contact between conductive elements and body tissue, without tissue damage. This cuff accommodates varying tissue diameters and simplifies manufacture and surgical placement.
