Stent-Graft Prosthesis, System And Method For Improved Delivery Of A Stent-Graft Prosthesis

A medical system including a first main stent prosthesis having at least one lateral branch, a second side stent-graft prosthesis having a body of a generally tubular wall structure, and a guiding element;

• wherein:
• said lateral branch having a distal orifice at a distal end being configured for receiving said second side stent-graft prosthesis connectable thereto, characterized in that
• said tubular wall structure of said second side-stent graft prosthesis including an orifice element configured for receiving said guiding element through its orifice, and
• said guiding element having a distal end positioned proximally at an interior and at a distance from said distal orifice of said lateral branch at a connection point of said side branch;
• such that said stent-graft prosthesis is arrangeable slideably along said guiding element over said orifice element to said orifice of said lateral branch for delivery and deployment of said side stent-graft prosthesis, preferably through a delivery lumen of a catheter with its lumen threadable over said guiding element,
• wherein said second side stent-graft prosthesis extends distally beyond said connection point when moved with its orifice element over said guiding element for engagement at said connection point;
• and
• said orifice element preferably being a guiding mate.
