Guidewire-access modular intraluminal prosthesis with connecting section

A bifurcated intraluminal modular prosthesis adapted for insertion into and assembly within a bifurcated body lumen to repair the lumen, said prosthesis comprising a pair of tubular mating members comprising a female mating member and a male mating member adapted for in vivo assembly securely with one another, the pair of tubular mating members having an assembled configuration and a disassembled configuration;

• the female mating member comprising a main body and at least one depending member having a funnel-shaped end and a connecting segment that tapers with decreasing diameter from the main body to the funnel-shaped end along a first axial length, the funnel-shaped end flaring with increasing diameter from the connecting segment along a second axial length, the connecting segment and adjacent funnel-shaped end together forming an hourglass-shaped end, the female mating member having an outer surface covered with a biocompatible graft material except for one or more anchoring ends and, optionally, said funnel-shaped end, said funnel-shaped end having an inner mating surface covered with said biocompatible graft material;
• the male mating member comprising an hourglass-shaped end in both the disassembled configuration and the assembled configuration, the hourglass-shaped end in the assembled configuration comprising a tapered section adapted to contact the female mating member connecting segment and a flared section adapted to contact the female mating member funnel-shaped end all along the second axial length, the male mating member having an outer surface covered with said biocompatible graft material;
• the hourglass-shaped ends of the female mating member and the male mating member adapted to self-lock with one another in the assembled configuration to form a tight seal.

An intraluminal prosthesis adapted for insertion from a distal location into and assembly within a body lumen to repair the lumen in a proximal location, said prosthesis comprising a pair of tubular mating members comprising a female mating member and a male mating member adapted for in vivo assembly securely with one another, the pair of tubular mating members having an assembled configuration and a disassembled configuration;

• the female mating member comprising a main body portion that branches into at least two depending members, each depending member having an external diameter, at least one of said depending members having a funnel-shaped end and having a connecting segment having a defined axial length connecting said main body portion to said funnel-shaped end, the funnel-shaped end having a diameter that increases distally in a first slope and the connecting segment having a diameter that decreases distally in a second slope, the funnel-shaped end and the connecting segment together forming a female interface for receiving the male mating member;
• the male mating member comprising in both the disassembled configuration and the assembled configuration a flared section having a diameter that increases distally and a tapered section having a diameter that decreases distally, the flared section and the tapered section together forming a male interface for connection with the female interface, the flared section in the assembled configuration adapted to contact the female mating member funnel shaped end and having the first slope and the tapered section in the assembled configuration adapted to contact the female mating member connecting segment and having the second slope;
• the female interface and the male interface adapted to self-lock with one another in the assembled configuration to form a tight seal.
