摘要：
The invention is intended for use in medicine and enables maximally precise, quick and safe positioning of a coronary stent in the case of uncomplicated and complicated anatomical injuries of the coronary vascular bed, and also when stenting renal and visceral arteries. The claimed device consists of a body with a truncated anterior portion and a cylindrical posterior portion, which are interconnected such that the cylindrical posterior portion of the body is rotatable about its own axis. The inside surface of the cylindrical posterior portion of the body is provided with a thread that is capable of engaging a lip of a slider disposed on guides inside the posterior portion of the body. The slider is connected to a barrel of a gripper having vanes with elastic elements at a delivery system gripping point such that the gripper is rotatable about its own axis, wherein the vanes of the gripper have protuberances disposed in a clamping cylinder which is arranged inside the body of the device and squeezes and releases the vanes of the gripper under the action of a release member consisting of a pressure surface on the outer truncated portion of the body and vanes arranged inside the body at an angle to one another and to the clamping cylinder, respectively releasing or locking the delivery system in the device. When preparing the device for use, the coronary stent is first inserted on a delivery system into the device； the coronary stent is then manually manoeuvred on the delivery system to the injured site of the coronary artery, the delivery system is locked by the vanes of the gripper, and the stent is moved in a longitudinal direction on the delivery system and positioned in the coronary artery by circumferential rotation of the cylindrical posterior portion of the device.L'invention est destinée à s'utiliser en médecine humaine à des fins d'un positionnement précis, rapide et sans danger d'un stent coronaire lors de lésions anatomiques simples ou complexes du lit cor
