Surgical implant devices and methods for their manufacture and use
First Claim
1. A sealable vascular system, comprising:
- an endovascular implant to be delivered in a compressed or folded state to an implantation site, said endovascular implant including;
a tubular implant body; and
a sealable circumferential collar at said tubular implant body and including;
a variable sealing device; and
a control lead traversing from said variable sealing device to a user for controlling said variable sealing device by the user, said variable sealing device and said control lead being cooperatively operable to reversibly expand and contract said sealable circumferential collar such that said sealable circumferential collar is circumferentially adjustable during deployment thereof to achieve a repositionable fluid-tight seal between said sealable circumferential collar and the internal walls of the implantation site.

Abstract
A sealable vascular system includes an endovascular implant to be delivered in a compressed or folded state to an implantation site. The endovascular implant includes a tubular implant body and a sealable circumferential collar at said tubular implant body and including a variable sealing device and a control lead traversing from said variable sealing device to a user for controlling said variable sealing device by the user, said variable sealing device and said control lead being cooperatively operable to reversibly expand and contract said sealable circumferential collar such that said sealable circumferential collar is circumferentially adjustable during deployment thereof to achieve a repositionable fluid-tight seal between said sealable circumferential collar and the internal walls of the implantation site.

4. An endovascular implant for placement in a vascular defect, the implant comprising:
-
a tubular implant body; a sealable circumferential collar at said tubular implant body, said sealable circumferential collar including a variable sealing device operable to reversibly expand and contract said sealable circumferential collar such that said sealable circumferential collar is circumferentially adjustable during deployment thereof to achieve a repositionable fluid-tight seal between said sealable circumferential collar and internal walls of a blood vessel adjacent the vascular defect; and a control lead connected to said variable sealing device, said control lead traversing from said variable sealing device to a user for controlling said variable sealing device by the user. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method of treating a vascular defect in a blood vessel within a patient, the method comprising:
-
placing an elongated main implant delivery catheter through a peripheral vascular entry into the blood vessel having internal walls, said implant delivery catheter having; a catheter proximal end and a catheter distal end; an implant delivery catheter sheath defining an implant delivery catheter lumen; and an endovascular implant disposed within said implant delivery catheter lumen in a compressed or folded state, the endovascular implant having; a tubular implant body having a proximal end and a distal end; and a sealable circumferential collar at said tubular implant body including a variable sealing device having a control lead operatively connected thereto, said control lead being operable to traverse said implant delivery catheter from said variable sealing device at least to said catheter proximal end when housed therein for interface by a user; employing real-time visualization to monitor implant placement in the blood vessel; distally retracting said implant delivery catheter sheath to expose said proximal end of said endovascular implant; cooperatively manipulating said control lead and said variable sealing device to circumferentially adjust said sealable circumferential collar to achieve a fluid-tight seal between said sealable circumferential collar and the internal walls of the blood vessel adjacent the vascular defect, said control lead and said variable sealing device being cooperatively operable to reversibly expand and contract said sealable circumferential collar such that the fluid-tight seal is repositionable; distally retracting said implant delivery catheter sheath to expose said distal end of said endovascular implant; and removing said control lead and said implant delivery catheter through said peripheral vascular entry. - View Dependent Claims (18, 19, 20)

21. A system for circumferentially sealing within a lumen, comprising:
an implant to be delivered in a compressed or folded state to an implantation site, the implant comprising; a tubular body having a variable circumferential-sealing collar; and a control lead traversing from said collar to a user for controlling said collar by the user, said collar and said control lead being cooperatively operable to reversibly expand and contract said collar such that said collar is circumferentially adjustable during deployment thereof to achieve a repositionable fluid-tight seal between said collar and the implantation site.

22. A method of treating a vascular defect in a blood vessel within a patient, the method comprising:
-
employing real-time visualization to monitor placement of an endovascular implant in a compressed or folded state in the blood vessel, the endovascular implant having; a tubular implant body; a proximal end and a distal end; a sealable circumferential collar at said tubular implant body including a variable sealing device; and a control lead operatively connected to the variable sealing device and traversing therefrom to a user for interface by the user; and cooperatively manipulating said control lead and said variable sealing device to circumferentially adjust said collar to achieve a fluid-tight seal between said collar and the internal walls of the blood vessel, said control lead and said variable sealing device being cooperatively operable to reversibly expand and contract said collar such that the fluid-tight seal is repositionable.
