An insertion instrument is configured to eject at least one anchor body into respective target location, and subsequently apply a predetermined tensile force at least one actuation member of the at least one anchor member so as to actuate the at least one anchor body from a first configuration to a second expanded configuration. The insertion instrument can include a tension assembly that applies the predetermined tensile force to the at least one actuation member. The predetermined tensile force can be defined by a distance of travel, a predetermined failure force of a fuse, or a combination of distance of travel and a predetermined failure force of a fuse.一插入工具係建構為射出至少一錨體部到個別的目標區位內，且隨後施加一預定拉力於至少一錨構件的至少一致動構件藉以將至少一錨體部從一第一組態致動到一第二擴張組態。插入工具可包括一伸張組件，其施加預定拉力到至少一致動構件。預定拉力可藉由一移行距離、一熔絲的一預定失效力、或移行距離及一熔絲的一預定失效力之組合所界定。
