A suture (100) for cosmetic surgery comprises a bioresorbable elongate filament structure (102) having first and second ends (104, 106). At least ten bioresorbable frusto-conical elements (108) suitable for subcutaneous tissue engagement are received movably upon the filament structure. At least twelve protrusions (110) are disposed along the filament structure wherein the elements and protrusions are disposed as spatially-separated first and second sets (116, 118), each of at least 5 elements and at least 6 protrusions. The first set is proximal to the first needle and distal to the second needle, and the second set is proximal to the second needle and distal to the first needle. The elements are orientated in a bidirectional manner such that, when the filament structure is taut, the narrower ends of the elements in the first and second sets are orientated towards the first and second needles. When said elements are in the furthest position from their respective proximal needles that is allowed by the configuration of the suture (120, 122), and the points at which the filament structure is coupled to said needles (124, 126), is at least 10 cm (128, 130). |
