Abstract
A seal assembly that seals opening in the wall of a blood vessel has a first sealing element for placing inside the lumen of the blood vessel and to engage the interior wall surface, a shaft integrally formed with the first sealing element and fixed in a predetermined configuration relative to the first sealing element, an outer floating element slidingly movable along the shaft; and a second sealing element, the second sealing element slidingly movable relative to the first sealing element along the shaft to engage the outer floating element and position the outer floating element against the exterior surface and the first sealing element against the interior surface of the blood vessel to seal the opening in the blood vessel.
Claims15
A seal assembly for sealing an opening in the wall of a blood vessel, the blood vessel having an interior wall surface, exterior wall surface, and a lumen, the seal assembly comprising:
- a first sealing element for placing inside the lumen of the blood vessel;
- a shaft having a rigid formation with the first sealing element and in a same predetermined configuration relative to the first sealing element before and after insertion of the first sealing element into the lumen, the shaft having a length sufficient to extend through the opening of the blood vessel and at least a portion of any overlying tissue;
- an outer floating element slidingly movable along the shaft, the outer floating element having a top surface and a bottom surface;
- and
- a second sealing element, the second sealing element slidingly movable relative to the first sealing element along the shaft to engage the outer floating element and configured to position the bottom surface of the outer floating element against the exterior wall surface of the blood vessel to seal the opening in the blood vessel, wherein the shaft has at least two sides, the at least two sides each having a groove along a portion thereof and the outer floating element has an aperture to receive the shaft therethrough, the aperture generally being rectangular and having two protrusions extending into the aperture and configured to extend into the groove on a respective side of the shaft.
A seal assembly for sealing an opening in the wall of a blood vessel, the blood vessel having an interior wall surface, exterior wall surface, and a lumen, the seal assembly comprising:
- a first sealing element for placing inside the lumen of the blood vessel;
- a shaft having a rigid formation with the first sealing element and in a same predetermined configuration relative to the first sealing element before and after insertion of the first sealing element into the lumen, the shaft having a length sufficient to extend through the opening of the blood vessel and at least a portion of any overlying tissue, and the shaft and the first sealing element are a single one-piece component;
- a flexible member surrounding at least a portion of the shaft adjacent the first sealing element;
- and
- a second sealing element, the second sealing element slidingly movable relative to the first sealing element along the shaft and configured to seal the opening in the blood vessel, wherein the shaft has at least two sides, the at least two sides each having a groove along a portion thereof and the outer floating element has an aperture to receive the shaft therethrough, the aperture generally being rectangular and having two protrusions extending into the aperture and configured to extend into the groove on a respective side of the shaft.
