An implantable adjustable body tissue cuff, apparatus and method. The cuff is an elastomeric strap of biocompatible non-conductive material. The strap's 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.

System and method for treatment of sexual dysfunction
The invention relates to a method of treating sexual dysfunction. The method includes stimulating sacral nerve roots, S2 and / or S3, with electromagnetic stimulation in or about the sacrum. The stimulation may be achieved with leads terminating in electrodes that extend with an emerging sacral nerve root or extend transverse the sacrum at or about the location of the nerve root to be stimulated. Alternately, spiraled electrodes and nerve cuffs may be used to stimulate the nerve root within the sacrum, as it emerges from the sacrum, or outside the sacrum. In this manner, the selected sacral nerve root may be stimulated to provide genital stimulation and thereby induce orgasm.
