Patent ID: 8864810

Claim:
A system to implant a vascular prosthesis ( 110 ) in a blood vessel ( 1 ) comprising: an implant device; and an introduction catheter ( 10 ) comprising a proximal end ( 11 ), a distal end ( 12 ), and a distal aperture at the distal end ( 12 ) of the introduction catheter ( 10 ), the implant device being designed to slide from the proximal end ( 11 ) to the distal end ( 12 ) of the introduction catheter ( 10 ), the implant device comprising i) a single balloon ( 128 ) and ii) a dilation catheter ( 120 ) arranged to supply fluid to the balloon ( 128 ), the dilation catheter ( 120 ) having a proximal end, a distal end ( 124 ), and a distal part designed to be introduced into the vessel ( 1 ), wherein the distal part of the dilation catheter ( 120 ) comprises a bend ( 123 ) and an upstream portion ( 121 ) and a downstream portion ( 122 ) that are contiguous to the bend ( 123 ), the bend of the dilation catheter ( 120 ) being arranged between the downstream and upstream portions ( 121 , 122 ) of the dilation catheter ( 120 ) and, respectively, the proximal end and the distal end ( 124 ) of the dilation catheter ( 120 ), the balloon ( 128 ) being entirely supported by the downstream portion ( 122 ) of the dilation catheter ( 120 ), wherein the system is arranged so that when the dilation catheter ( 120 ) is placed in the introduction catheter ( 10 ), the downstream portion ( 122 ) of the dilation catheter ( 120 ) is being substantially folded along the upstream portion ( 121 ) of the dilation catheter ( 120 ) and the bend ( 123 ) of the dilation catheter ( 120 ) is being positioned below the downstream portion ( 122 ) and the upstream portion ( 121 ) of the dilatation catheter ( 120 ), thus facing the distal aperture of the introduction catheter ( 10 ), the configuration allowing thereby to introduce into a blood vessel, through a puncture, first the bend ( 123 ) of the dilatation catheter ( 120 ) and thereafter the balloon ( 128 ) entirely supported by the downstream portion ( 122 ) of the dilation catheter ( 120 ) and the distal end ( 124 ) of the dilatation catheter ( 120 ), and wherein the system being thereby configured to implant the vascular prosthesis perpendicular to a puncture in a vessel/artery, through which the prosthesis is to be inserted, while running in a direction parallel to the longitudinal axis of the blood vessel.
