Ovation 4257A58H16 Module

Westinghouse Ovation 4257A58H16 Brand New Module

Introduction

To facilitate device introduction into the access vessel, the aortic body, the iliac limbs, and the iliac extensionsare preloaded into delivery catheters as illustrated in Figure 3 – Figure 5. The delivery catheters each have alumen for use with a guidewire to facilitate access and deployment. The inner catheter of the Ovation iX stentgraft delivery systems can be withdrawn through the outer sheath, with the outer sheath remaining in thevasculature to facilitate the introduction of ancillary devices. 

The aortic body delivery system includes anintegrated crossover lumen as an option to facilitate guidewire access.The aortic body is deployed via the aortic body delivery catheter which has a connection to the distal legs of theaortic body. During aortic body stent graft deployment, the device is first positioned and the sheath is retracted.The proximal stent is then deployed using stent release knobs on the handle. The fill polymer is then deliveredthrough the fill connector port using the Autoinjector.The contralateral and ipsilateral iliac limbs are each deployed via iliac limb delivery catheters. After deploymentof the aortic body, a guidewire is placed from the contralateral access site into the contralateral distal leg of theaortic body; the integrated crossover lumen can be utilized to facilitate the process. The contralateral iliac limbis advanced into position and deployed into the aortic body leg by retracting the catheter sheath with thecatheter in the appropriate position. 

The contralateral limb delivery catheter is then used as an integral sheath(as described above) or withdrawn from the vasculature. After the fill polymer cures within the sealing rings, theaortic body delivery catheter is detached from the fill port of the graft and is used as an integral sheath (asdescribed above) or withdrawn from the vasculature. The ipsilateral iliac limb delivery catheter is advancedover the ipsilateral guidewire and deployed using the method described above for the contralateral limb. Theipsilateral limb delivery catheter is then used as an integral sheath (as described above) or withdrawn from thevasculature.
