Abstract
Purpose: To demonstrate the feasibility of a novel technique that modifies the configuration of a thoracic stent-graft after deployment to comply with the arch curvature. Technique: The principle of a Bowden cable has been applied to direct a conventional thoracic stent-graft in situ after deployment. A suture placed at the proximal inner curve of a conventional thoracic stent-graft is fitted with a sliding, self-locking knot attached to a line that runs inside a catheter through the central rod of the stent-graft. Traction applied to this line directs the endograft post deployment, which allows for better apposition to the aortic wall. Shortening the inner curve makes the stent-graft bend. The extent of bending is fully controlled by the... (More)
Purpose: To demonstrate the feasibility of a novel technique that modifies the configuration of a thoracic stent-graft after deployment to comply with the arch curvature. Technique: The principle of a Bowden cable has been applied to direct a conventional thoracic stent-graft in situ after deployment. A suture placed at the proximal inner curve of a conventional thoracic stent-graft is fitted with a sliding, self-locking knot attached to a line that runs inside a catheter through the central rod of the stent-graft. Traction applied to this line directs the endograft post deployment, which allows for better apposition to the aortic wall. Shortening the inner curve makes the stent-graft bend. The extent of bending is fully controlled by the surgeon and held in place with the sliding knot. A release mechanism allows removal of all luminal components of the mechanism. Conclusion: The described technique of directing a thoracic stent-graft in situ seems feasible and enables better apposition of the stent-graft in a glass model. It may improve the durability of thoracic stent-grafts in the aortic arch. (Less)
