1 Midterm results of the multicenter trial of the Powerlink bifurcated system for endovascular aortic aneurysm repair  Jeffrey P. Carpenter, MD  Journal of Vascular Surgery  Volume 40, Issue 5, Pages (November 2004) DOI: /j.jvs Copyright © 2004 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Powerlink bifurcated system. Device is a unibody bifurcated self-expanding fully stented endovascular graft. Stented endoskeleton is constructed as a single-wire body with a double spine, without sutures or welds. Stented portion is constructed of cobalt-chromium alloy. Endoskeleton is covered with graft material made of expandable polytetrafluoroethylene. Graft material is sutured to the endoskeleton only at the ends of the device. Device is supplied in 2 neck diameters (25 mm, 28 mm) and 2 fabric lengths (135 mm, 155 mm). Limbs of the bifurcated stent graft are 16 mm in diameter.

3 Fig 2 Kaplan-Meier comparison of patient survival through 24 months. There was no significant difference in survival between Powerlink (test) group and control group (P = .1507, log-rank test).

4 Fig 3 Kaplan-Meier comparison of major adverse event (MAE)–free survival through 24 months. While there were significantly fewer perioperative adverse events in the Powerlink cohort compared with the control group, over time there was no significant difference in overall adverse event–free survival (P = .456, log-rank).
