Abstract

An instrument places a stent axially and is reusable with different size stents. A loop on an arm extends tangentially so at least one bore aligns axially. A tab extends from the arm axially and from the loop in a plane. A ring on a limb extends tangentially and has an axially aligned hole in a plane. A bracket extends from the tab over and in front of the limb. A tube extends for coaxial deposition axially, into the bore and the hole locating the ring forward of the loop. An end on the tube opposite the bore grips the stent. A sheath coaxial to the tube slides along the end and extends from the hole. A sheath cavity near the end is for the stent. A shaft in the plane attaches to the bracket parallel and axially conjugates with the limb and arm prevents rotation. An axial control in the arm for selective movement relative to the shaft adjusts the position of the shaft to the arm. A method of assembling the instrument has steps of extending the tube to support the stent, locating the ring on the tube forward of the loop, sliding the sheath and accommodating the stent in the cavity within the end. Conjugating the shaft with the limb and the arm and moving the axial control for adjusting axial position of the shaft.
