OVAL VASCULAR CLOSURE DEVICE AND METHODS
A tissue puncture closure device having an anchor, a suture, a sealing plug, a compaction assembly, a carrier tube, and an insertion sheath. The suture is connected to the anchor at a distal end of the suture. The sealing plug is slidingly mounted to the suture and positioned proximal of the anchor. The compaction assembly is operable to compact the sealing plug toward the anchor. The carrier tube has the sealing plug positioned therein during delivery to a vessel puncture. The insertion sheath is insertable through the vessel puncture and configured to receive the carrier tube and anchor. At least the carrier tube has a cross-sectional shape with a greater width dimension than a height dimension.
1 . A tissue puncture closure device, comprising:
an anchor;
a suture connected to the anchor at a distal end of the suture;
a sealing plug slidingly mounted to the suture and positioned proximal of the anchor;
a compaction assembly operable to compact the sealing plug toward the anchor;
a carrier tube having the sealing plug positioned therein during delivery to a vessel puncture;
an insertion sheath insertable through the vessel puncture and configured to receive the carrier tube and anchor, the insertion sheath having a cross-sectional shape with a greater width dimension than a height dimension.
2 . The tissue puncture closure device of claim 1 , wherein the cross-sectional shape of the insertion sheath is oval.
3 . The tissue puncture closure device of claim 1 , wherein the carrier tube has a cross-sectional shape with a greater width dimension than a height dimension.
4 . The tissue puncture closure device of claim 1 , wherein the sealing plug has a cross-sectional shape with a greater width dimension than a height dimension.
5 . The tissue puncture closure device of claim 1 , wherein the anchor has a variable width along its length.
6 . The tissue puncture closure device of claim 1 , wherein the anchor has a variable thickness along its length.
7 . The tissue puncture closure device of claim 1 , wherein the anchor includes a suture attachment point positioned at a midpoint along its length.
8 . The tissue puncture closure device of claim 7 , wherein the anchor has a maximum width adjacent to the suture attachment point.
9 . A tissue puncture closure device adapted for insertion into and sealing of a tissue puncture, the tissue puncture closure device comprising:
an insertion sheath;
a carrier tube;
a sealing plug;
an anchor having a variable width dimension along its length;
a suture coupling the sealing plug to the anchor and extending through the carrier tube.
10 . The tissue puncture closure device of claim 9 , wherein the insertion sheath has a non-circular shaped cross-section.
11 . The tissue puncture closure device of claim 10 , wherein the non-circular shaped cross-section includes an oval shape.
12 . The tissue puncture closure device of claim 9 , wherein the sealing plug is positioned in the carrier tube, and the anchor and carrier tube are positioned in the insertion sheath.
13 . The tissue puncture closure device of claim 9 , wherein the insertion sheath and carrier tube each have a cross-sectional shape with a greater maximum width dimension than a minimum width dimension.
14 . The tissue puncture closure device of claim 9 , wherein the sealing plug has a non-circular cross-sectional shape.
15 . The tissue puncture closure device of claim 9 , further comprising a compaction member configured to compact the sealing plug toward the anchor, the compaction member having a non-circular cross-sectional shape.
16 . A method of sealing a puncture in a wall of a vessel, the method comprising:
providing a closure device having a sealing plug, an anchor, a suture connected to the anchor, a carrier tube and an insertion sheath, the sealing plug being positioned in the carrier tube and the carrier tube and anchor being positioned in the insertion sheath, at least the carrier tube having a cross-sectional shape with a greater width dimension than height dimension;
inserting the closure device through the puncture;
depositing the anchor within an interior of the vessel;
withdrawing the closure device to contact the anchor against an interior surface of the vessel and deposit the sealing plug adjacent to an exterior surface of the vessel;
connecting the sealing plug and anchor together with the suture to seal the puncture.
17 . The method of claim 16 , further comprising arranging the width dimension of the insertion sheath with a maximum width dimension of the puncture prior to inserting the closure device through the puncture.
18 . The method of claim 16 , wherein depositing the anchor includes withdrawing the insertion sheath relative to the carrier tube.
19 . The method of claim 16 , further comprising providing at least a portion of the insertion sheath and at least a portion of the carrier tube with the same cross-sectional shape.
20 . The method of claim 16 , further comprising providing the anchor with a variable width dimension along its length.
