Patent number: 9237960Abstract: An introducer assembly (100) including at its distal end a dilator tip (20) and an inner catheter for supporting an implantable medical device (1) for deployment, is provided with a plurality of strut elements (102, 202) extending from the dilator tip (20) to the proximal end of the medical device (1). The strut elements (102, 202) act to apply both a pulling and a pushing force against the proximal end of the medical device (1), having the effect of assisting in the correct positioning of the proximal end of the medical device in a patient's lumen, particularly where this is curved such as with the aortic arch. The strut elements (102, 202) form part of the introducer assembly and are removed from the patient following the deployment procedure. The device avoids the need for bare stents at the end of a stent graft.Type: GrantFiled: October 9, 2009Date of Patent: January 19, 2016Assignee: Cook Medical Technologies LLCInventors: Erik E.
