ASSEMBLY WITH CORE WIRE AND RETAINER FOR ATTACHMENT TO BLOOD VESSEL Russian patent published in 2015 - IPC A61M25/04 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment and can be used when implanting a stent graft inside a blood vessel. An assembly for the detachable fixation of a transport wire and the insertion of the tubular element into the blood vessel comprises a core wire having the distal end to be inserted into the blood vessel, and the proximal end, and a retainer for detachable attachment to an inner side of the blood vessel. The retainer is configured to move towards the proximal end of the wire independently from the wire. The wire comprises a unit to prevent the distal motion of the retainer beyond the above prevention unit. The retainer has a deformable section having the central portion attachable to the inner side of the blood vessel at the preset length in the first longitudinal direction of the blood vessel. The central portion is a braided or interlaced element. The distal portion is attached to the deformable section. The proximal portion is attached to the deformable section. The retainer is configured to keep attached to the inner side of the blood vessel, when a traction force of at least 0.1H is applied to the core wire and to the retainer through the prevention unit.

EFFECT: technical effect consists in fixing the transport wire reliably.
