Bifurcation graft deployment catheter

An endoluminal graft deployment catheter, comprising:

• an elongate flexible body, having a proximal end and a distal end;
• a proximal outer tube section, having a proximal end and a distal end;
• a distal outer tube section, having a proximal end and a distal end,
• an intermediate tube extending through the proximal outer sheath tube section and beyond the distal end;
• the intermediate tube having a first portion and a second portion. the first portion having a larger diameter than the second portion to form a distally facing surface;
• a central core, extending through the proximal and distal outer tube sections and the intermediate tube.

An endoluminal graft deployment catheter, comprising:

• an elongate, flexible body, having a proximal end and a distal end;
• a proximal outer tube section having a proximal end and a distal end;
• a distal outer tube section, having a proximal end and a distal end;
• an intermediate tube extending through the proximal outer sheath tube section and beyond the distal end:
• a central core, extending between the proximal outer tube section and the distal outer tube section and the intermediate tube, wherein at least one of the proximal outer tube section and the distal outer tube section is axially moveable between a first position in which the proximal outer tube section and the distal outer tube section are adjacent each other, and a second position in which the proximal outer tube section and the distal outer tube section are spaced apart, the outer tube section and the distal outer tube section forming a junction when in the first position;
• and
• a tubular sheath having an open distal end and a proximal end, the tubular sheath defining proximal cavity for receiving a proximal end of a prosthesis, the tubular sheath necking down from a first larger diameter to a second smaller diameter at the proximal end to form a generally conical section of the proximal cavity, and
• a generally conical plug positioned in the generally conical section of the proximal cavity, the plug defining a distal surface that faces a proximal end of the prosthesis.
