device and method for safe positioning of a coronary stent within coronary arteries

摘要

the present invention relates to a medical device, aiming to precisely position the coronary stent in the case of anatomical lesions complicated or not of the coronary bed, and renal stent, visceral arteries. comprises housing, with cylindrical rear truncated front parts, connected together, where the rear is rotating. on the inner surface of the rear, rose-shaped, capable of engaging protrusion in a rotor, arranged on the guides, inside the rear. the rotor is connected to a fixing medium bushing, with flaps of elastic fixing members of the distribution system (distributor), where the fixing means is rotatable, the flaps are provided with protrusions arranged on a pressure roller inside the housing to contract them and release them comprising the pressure surface on the outside of the housing, and the flaps arranged within the housing at an angle to each other and the pressure roller to release and secure the dispenser. in preparation for use, the coronary stent carried by the distributor is progressively inserted into the device, to which the coronary stent, carried by the distributor, is guided to the affected area of the coronary, and fixed, and by circumferentially rotating the cylindrical rear of the device, the stent conducted by the distributor is positioned inside the artery.
