摘要

The present invention is suitable for medical use that enables as fast, accurate and safe positioning of a coronary stent as possible in the case of simple and complex anatomical lesions of coronary artery disease and stenting of renal and visceral arteries. The claimed device comprises a housing with a tail, a screw rotating wheel, a screw, a runner with threaded elements, a scale for identification of a runner with an elastic coupling with arranged elastic fastening elements, two elements, namely a spring and on the housing. and a plug comprising a retaining button disposed on the In preparation for use, the coronary stent carried by the delivery system is progressively inserted inside the device, and then the coronary stent carried by the delivery system is manually advanced to the affected area of the coronary artery, the delivery system is fixed and The stent is positioned in the coronary artery by means of a screw rotating wheel. A second embodiment includes a housing with a tail, a screw rotating wheel, a screw, a rotating gear, a hold down cylinder, and a retaining button with a spring for positioning guides for the delivery system within the housing. In preparation for use, the coronary stent carried by the delivery system is progressively inserted inside the device, and then the coronary stent carried by the delivery system is manually advanced to the affected area of the coronary artery, the delivery system is fixed and The stent is positioned in the coronary artery by means of a screw rotating wheel.
