UA88588U - Device for endovascular prosthetic repair of aneurism of aorta with precise positioning of distal part of endoprosthesis - Google Patents

Abstract

A device for the endovascular prosthetic repair of aneurism of aorta contains the canal for the guide generated by the flexible deflector, the steel tube, and the control handle. The tubular pusher with the control handle is located coaxially. The control handle comprises the clamp and the transport tube with compressed endoprosthesis inside. The device is equipped with the rest tube ended with the small control handle with the small clamp on one side with the guide deflecting bushing locating at the opposite end. The said rest tube is located coaxially between the canal for the guide and the control system allowing for the displacement relative to each other and fixation at the required position. The control system is equipped with the proximal tip with the loop and the guiding tie-rod exteriorized to the control handle allowing for connection and disconnection with the distal part by passing the loop through the sheath of the distal part of endoprosthesis with the proximal end of the guiding tie-rod being inserted into the free end of the distal part. The total length of the transport tube is calculated as follows:,wherein- total length of the transport tube;- length of the holder tip (20÷30 mm);- length of the endoprosthesis;- length of the deflecting bushing;- length of the proximal part of the transport tube attached to the deflector.
