A tool for delivering and applying a clamping implant (9 109) via a puncture in skin tissue (3) and underlying tissue (2) of a patient, comprising a hollow needle (4 104) bounding a lumen (5 105) and forming a helix, a plunger (6 106) of which a distal portion extends in longitudinal direction inside the lumen (5 105), and a plunger operating member (7 107) engaging a proximal portion of the plunger (6 106) projecting from the needle (4 104), for screwing the plunger (6 106) further into or out of the needle (4 104) by screwing rotation of the needle (4 104) relative to the plunger (6 106). A system including such a tool and a method for delivering and applying a clamping implant (9 109) using such an instrument are also described.
