Sealable endovascular implants and methods for their use
First Claim
1. A sealable vascular endograft system for placement in a vascular defect, comprising:
- an elongated implant delivery catheter having a catheter proximal end and a catheter distal end and shaped to be disposed within a blood vessel having internal walls, the implant delivery catheter including;
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 including;
a tubular implant body; and
a sealable circumferential collar at the tubular implant body and 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 variable sealing device and the control lead cooperating to reversibly expand and contract the sealable circumferential collar such that the sealable circumferential collar circumferentially adjusts during deployment thereof to achieve a repositionable fluid-tight seal between the sealable circumferential collar and the internal walls of the blood vessel.

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.

14. A method of treating a vascular defect in a blood vessel within a patient, the method comprising:
-
providing an endovascular implant with; a tubular implant body; a sealable circumferential collar at the tubular implant body and having a variable sealing device to reversibly expand and contract the sealable circumferential collar; and a control lead operatively connected to the variable sealing device to reversibly expand and contract the sealable circumferential collar, the control lead traversing from the variable sealing device to a user for interface by the user when the endovascular implant is at the vascular defect; guiding the endovascular implant in a compressed or folded state to the vascular defect; cooperatively manipulating the control lead and the variable sealing device to circumferentially adjust the sealable circumferential collar to achieve a fluid-tight seal between the sealable circumferential collar and the internal walls of the blood vessel adjacent the vascular defect, the manipulation of the control lead and the variable sealing device reversibly expanding and contracting the sealable circumferential collar during deployment thereof to reposition the fluid-tight seal; and removing the control lead from the patient. - View Dependent Claims (15, 16, 17)
