Guidewire-access modular intraluminal prosthesis with connecting section
First Claim
1. An intraluminal modular 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 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 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.

Abstract
A multi-component intraluminal prosthesis is adapted for insertion into and in vivo assembly within a body lumen to repair the lumen, the components including secure and/or fluid-tight mating sections. The prosthesis comprises a female mating member comprising a main body portion, a funnel-shaped end, and a sealing segment connecting the main body portion to the funnel-shaped end; and a male mating member adapted for in vivo assembly with the sealing segment of the female mating member. The sealing segment may be essentially cylindrical or it may taper with decreasing diameter from the main body to the funnel-shaped end. The sealing segment and adjacent funnel-shaped end may together form an hourglass-shaped end. A biocompatible graft material may cover the inner surface of the funnel-shaped end. To secure a fluid-tight seal, the outer surface of the male member and the inner surface of the female member are covered with a biocompatible graft material in their respective mating segments. The prosthesis may form a bifurcated intraluminal prosthesis adapted, for example, for deployment in the infra-renal aorta and the iliac arteries, where the main body component forms the main aortic body, the integral first leg member forms the first iliac segment, and the second leg member forms the second iliac segment.
