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 device for positioning a coronary stent within coronary arteries is described. The device has a housing having a cylindrical front part and an internally-threaded cylindrical rear part connected to each other by a slot allowing the cylindrical rear part to rotate around an axis. The cylindrical front part of the housing is provided with recesses for fixing a coronary guide. A runner is provided with projections for engaging an internal thread of the cylindrical rear part of the housing. The device includes a structure for clamping disposed in a threaded runner cap. The runner is disposed inside a retainer with ears projecting into side holes on both sides of the housing. Clamping is operable by rotation of the rear part of the device housing. A method for positioning a coronary stent within coronary arteries is also described.

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： The device is 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.
