摘要:
The present invention provides for maximum accuracy, rapid and safe positioning of coronary stents in the case of complex and uncomplicated histological lesions of the coronary bed and for stent placement of the renal and visceral arteries. Suitable for use in medicine. The claimed device comprises a housing having an interconnected anterior truncated portion and a cylindrical rear portion, the cylindrical posterior portion being rotatable about its axis. A threaded portion is formed on an inner surface of the cylindrical rear portion of the housing so as to engage with a protrusion of a runner arranged on a guide inside the rear portion of the housing. The runner is connected to a bushing of the gripping means having a flap with an elastic member at the grip point of the delivery system so that the gripping means is rotatable about its axis, the gripping means flap being acted upon by the release means. A protrusion arranged in a pressure roller installed inside the device housing is provided for retracting and releasing the gripping means flap. Releasing means are arranged in the housing at an angle to the pressure surface at the truncated outer portion of the housing, relative to each other and to the pressure roller, for releasing and securing the delivery system within the device, respectively. And a flap. In preparation for use, the coronary stent carried by the delivery system is pre-inserted gradually inside the device beforehand, after which the coronary stent carried by the delivery system is manually advanced to the affected part of the coronary artery and the delivery system is operated by the gripping means flap. By circumferentially rotating the cylindrical posterior portion of the device, carried by the delivery system, the stent is longitudinally displaced and positioned within the coronary artery.本発明は、冠動脈床の複雑な及び複雑ではない組織的病変の場合、並びに腎臓、内臓動脈のステント留置のために、冠動脈ステントの最大限に正確、迅速かつ安全な位置決めを可能にするために医療において使用するのに適する。請求対象の装置は、相互に接続された切頭前部分及び円筒形後部分を有するハウジングを備え、円筒形後部分はその
