Stent delivery devices using micro cadeter

摘要

The present invention assists thereby place a stent in the blood vessels near the stent is a micro catheter assists possible to position the lesion close via the emitter securely, is discharged and recovered and easy for treatment positioning of the stent, in particular lesions occurred, It relates to a stent delivery device using a discharge and recovery of the catheter easier micro-emitter to the arrangement and treatment positioning of the stent that can easily perform the exhaust and recovery to the correct treatment position adjustment of the stent for treatment in the body cavity, and more specifically relates to an insertion device of the stent to the procedure a stent in the lumen of blood vessels have lesions occurred, the inner wire connection to the guide wire to move front and rear in the interior of the outer tube, and hanging on the stent on the surface of the inner wire forming that jam, and said stent engaging the engaging portion of the inner wire is a stent at the same time to move to the affected area along the inner diameter of the entry into the catheter in close-up procedure to the affected area micro-ground of the guide wire is not separated from the inner wire configuration and characterized in that; Effects that enable hadeorago a stent, such as stent portion discharging the stent when the lesion treatment onset in one place, such as cerebrovascular requiring blood vessels or the lumen of the particular diameter smaller precise procedure again recovered by re-treatment position or direction under control there is. ;
