Abstract
A stent graft (10; 40; 80) has a tubular body (12; 42; 82) of a biocompatible material and at least two fenestrations (18, 20; 48, 50; 84, 86, 88). The at least two fenestrations (10, 20; 48, 50; 84, 86, 88) are adjacent each other and each has a tube {24, 26; 54, 55; 90, 92, 94) extending into the tubular body (1 2; 42; 82). The tubes (24, 26; 54, 55; 90, 92, 94) are joined inside the tubular body (12; 42; 82) into a single larger tube (30; 60; 96) to facilitate catheterization.
