In a preferred application, e.g., the repair of vaginal prolapse after relocation of the vagina and any organs displaced by the prolapse, corrective surgery is initiated by applying a hollow tubular element, formed to forcibly insert a barbed anchor attached to a distal end of a first length of suture, without any incision, from the inside of the vagina through the vaginal wall (the supported tissue) into selected support tissue within a patient's pelvis. This involves puncturing and thus locally severe physical distressing of both the supported tissue and the support tissue. The barbed anchor is left in the support tissue as the tubular element is then withdrawn from the support tissue and out of the vagina, leaving the proximate end portion of the suture extending through the vaginal wall into the vagina. A second such anchor, with a second length of suture attached thereto, is similarly inserted adjacent to the first anchor. The proximate end portions of the sutures are tied to each other inside the vagina, to thereby secure the vaginal wall to the support tissue with corresponding punctures formed in each by the insertions of the two anchors being thereby held in respective, precisely aligned, intimate contact during healing. This results in a pair of fused scars that cooperate to permanently bond the vaginal wall locally to the support tissue. If the sutures and/or the anchors are made of absorbable material they will all eventually disappear and the fused scars will provide the permanent bonding. If the anchors are made of non-absorbable material they may remain where located. A plurality of such paired fused-scar bonds may be generated, at the surgeon's discretion, to ensure adequate support for the repaired vagina. The apparatus and method can be readily adapted to similarly effect deliberate, local, beneficial bonding between other adjacent living tissues in a patient.
