摘要： A body of the device to position a coronary stent or pull a catheter transducer for intravascular ultrasound is composed of a front and a rear portion each of which comprises two similar halves, a ring on the front smooth portion of the body and a brace over the rear portion of the rear portion of the body. The rear portion of the body overlaps the front portion of the body. The front portion of the body is truncated on one side thereof and continuously extends on the opposite side thereof in the form of a smooth cylindrical portion of a smaller diameter and a runner guide. A cylindrical slot with point elements is provided along the circumference of the cylindrical portion of the front portion of the body on the side of the runner guide. A cylindrical brace is mounted on the rear portion of the body.

摘要： A body of a device for positioning a coronary stent or a coronary balloon within coronary arteries is described. The body is formed of a front part and a rear part. The front body part represents, on the one side, a truncated part having a tubular extension with a cutout for connection to a Y-connector and, on the other side, successively passes into a cylindrical part, a cylindrical smooth part of a smaller diameter and a runner guide. The smooth surface of the rear body part is housed over the cylindrical smooth front body part, and the inside surface provided with the circumferential double-thread for engaging with the runner protrusions is housed over the runner. Through-holes for introducing the coronary stent or coronary balloon delivery system inside the device housed in the body are formed in the tubular extension of the front body part.

摘要： extending slot so that the rear part of the housing is rotatable, a runner with a cap screwed on the extending slot so that the rear part of the housing is rotatable, a runner with a cap screwed on the runner thread, a collet with hooks accommodated in the runner so at to be rotatable around its axis, a retainer with ears, wherein the runner cap is arranged inside the retainer. When the device is prepared for use, a coronary stent: carried by a delivery system is first progressively inserted inside the device and then the coronary stent carried by the delivery system is advanced manually to an affected area of a coronary artery, the delivery system is fixed Inside the device and is positioned within a coronary artery by means of rotating the rear part of the housing.
