DEVICE FOR FIXATION OF PROSTHESIS TO VESSEL Russian patent published in 2013 - IPC A61B17/115 A61B17/11 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to vascular surgery, in which prosthesis is introduced into vessel and fixed on internal wall of vessel. Device for fixation of prosthesis to first and second ends of vessel contains working part and stem part. Working part contains, at least, one fixing element. Stem part is made with possibility of placing prosthesis in it. Device is provided with pusher, made with possibility of travel along stem part to ensure coming out of fixing element. First end of prosthesis covers working part and is connected with it with possibility of detachment. Second end of prosthesis is connected with possibility of detachment with gripe. Stem part is intermediate with respect to working part and gripe. Gripe contains upper and lower handles made with possibility of approach to each other and release in such a way that pusher can be longitudinally moved along stem part. Working part contains main case, in which rotation elements and slotted elements are located, rotation and slotted elements being located in anterior and posterior groups. Method of attaching distal and proximal ends of prosthesis to distal and proximal ends of vessel lies in the following. Device, which contains working part with, at least, one fixing element, is taken. Working part is delivered to distal end of vessel. Distal end of prosthesis is fixed to distant end of vessel by means of fixing element. Working part is delivered to proximal part of vessel. Proximal end of prosthesis is fixed to proximal end of vessel by means of fixing element and working part is removed from vessel. Method of attaching prosthesis to first and second ends of vessel, in accordance with the second version, lies in the following. Device, which contains posterior gripe, anterior working part and intermediate stem part, is taken. First fixing elements and second fixing elements are loaded into anterior working part. Stem part is made with possibility of placing on it prosthesis in such a way that distal end of prosthesis is connected with working part, and proximal end of prosthesis is connected with gripe. Device contains pusher, made with possibility of travel along stem part for bringing anterior working part into action. In accordance with the method additionally introduced into vessel are anterior working part and, at least, part of stem part for delivery of distal end of prosthesis to first end of vessel. Pusher is moved along stem part to bring into action anterior working part and ensure coming out of first fixing elements in radial direction to attach distal end of prosthesis to first end of vessel. Proximal end of prosthesis is detached from handle. Pusher is brought out. Anterior working part and stem part are brought out along vessel to deliver proximal end of prosthesis to second end of vessel. Pusher is introduced along stem part to bring anterior working part into action and ensure coming out of second fixing elements in radial direction to attach proximal end of prosthesis to second end of vessel. Working part and stem part are removed from vessel'.

EFFECT: increased functionality.
