Prosthetic joints, components for prosthetic joints, superhard bearing and articulation surfaces, diamond bearing and articulation surfaces, substrate surface topographical features, materials for making joints, bearing and articulation surfaces, and methods for manufacturing and finishing the same, and related information are disclosed, including a diamond articulation surface for use in a prosthetic joint nnection means for adjustably attaching the second end of a strap means to said clamp rod; said second connection means including a second connection sleeve member for encircling said clamp rod, a screw member for extending through said second connection sleeve member and against said clamp rod to fixedly secure said second connection sleeve member to said clamp rod, and a bracket attached to said second connection sleeve member for allowing the second end of the strap means to be attached to said second connection means. aid electrosurgical generator assembly to apply said blend output to said electrode in electrical association with electrosurgical return to establish a said electrosurgical cut with adjacent coagulated cut surfaces. 5. The method of claim 1 in which: said step (b) provides said instrument with a fluid delivery channel extending from a fluid input in the vicinity of said base region to a fluid output at said forward end region and providing a supply of barrier fluid effective to retard the rate of neovascularization in fluid transfer communication with said fluid input; and including the step of: (f) expressing said barrier fluid from said fluid output for dispersion within said electrosurgical cut. 6. The method of claim 1 in which: said step (b) provides said instrument as having a said electrode which is thin and resilient, having a distal end connected with said support member at a connection location adjacent said tip and extending therefrom an arch defining distance; and said step (d) comprises the actuating steps of: (d1) urging said electrode forwardly toward said tip in compression to effect its deployment from an initial angular orientation of said forward end region as an outward movement in adjacency with one side of said peripheral extent of said targeted tissue, said outward movement being to an extent curving said electrode into an outwardly depending arch formation having an arch apex of circumscription height extensible over said targeted tissue when said forward end region is pivoted. (d2) pivoting said forward end region to a second angular position to, in turn, pivot said electrode over said targeted tissue peripheral extent to a next side thereof opposite said one side, (d3) effecting retraction of said electrode by urging it rearwardly toward said base region to effect its retracting movement to a retracted orientation below said targeted tissue peripheral extent to effect said electrosurgical cut along three contiguous regions of said targeted tissue peripheral extent. 7. A method for the treatment of an atrial flutter reentry circuit at a heart wall comprising the steps of: (a) providing a control system including an electrosurgical generator actuable to derive an electrosurgical cutting output and a mapping system controllable for response to an electrical parameter to locate the path of said reentry circuit; (b) providing an intravascular catheter electrically coupled with said control system, extending from a base region to a tip, having a forward end region adjacent said tip including a deployment slot longitudinally disposed between a forward location adjacent said tip and a rearward location, having a thin, resilient electrode at said forward end region having a distal end fixed to said catheter, extending within said deployment slot during insertion and removal modes and extending within said catheter beyond said rearward location an arch defining distance; (c) percutaneously introducing said catheter into the vascular system to locate said forward end region within the heart; (d) controlling said mapping system to locate the current flow position of said reentry circuit with respect to a heart wall; (e) positioning said deployment slot adjacent said heart wall at said current flow position in a longitudinal orientation effective for deriving a current interrupting impedance; (f) urging said electrode forwardly toward said tip in compression to effect its deployment outwardly from said deployment slot into an arch formation having an arch apex determined by said arch defining distance; (g) simultaneously with said step (f), actuating said electrosurgical generator to apply said cutting output to said electrode; and (h) retracting said electrode into said deployment slot by urging it rearwardly. 8. The method of claim 7 in which said steps (d) through (h) are reiterated until said re-entry circuit is beneficially interrupted by the impedance of necrotic tissue for
