Abstract
A coiled endoluminal prosthesis delivery assembly includes a catheter and a generally helical endoluminal prosthesis. The endoluminal prosthesis is placeable in a radially contracted state on the catheter. The assembly also comprises means for engaging proximal, intermediate and distal portions of the endoluminal prosthesis to maintain it in the first state, and means for controllably releasing the proximal, distal and intermediate portions to permit the endoluminal prosthesis to move towards a radially expanded state in a controlled manner. A method controllably releases the endoluminal prosthesis from the catheter within a hollow body structure. The method may include permitting at most 50%, and more preferably at most 25%, of the length of the endoluminal prosthesis to simultaneously move to the radially expanded state in contact with the hollow body structure.
