Abstract
A sealable vascular endograft system for placement in a vascular defect includes a delivery catheter shaped to be disposed within a blood vessel. The delivery catheter includes an implant delivery catheter sheath defining an implant delivery catheter lumen and an endovascular implant removably disposed within the implant delivery catheter lumen in a compressed or folded state for delivery thereof to the vascular defect. The endovascular implant includes a tubular implant body and a sealable circumferential collar including a variable sealing device and a control lead traversing from the variable sealing device to a user and controlling variability of the variable sealing device by the user. The sealing device and the control lead cooperate to reversibly expand and contract the sealable circumferential collar to circumferentially adjust during deployment thereof to achieve a repositionable fluid-tight seal between the sealable circumferential collar and the internal walls proximal to the vascular defect.
