Abstract

An internal tissue puncture closure method and apparatus. The method and apparatus provide a folded sealing plug that provides more surface area than conventional plugs to more fully cover and seal an external situs of an internal tissue puncture. The folded sealing plug may have a weave pattern that tends to cause the sealing plug to corkscrew into the internal tissue puncture as it is compressed toward an anchor placed inside of the tissue puncture.

Claims

1-41. -41. (canceled)

42. A method of closing a hole in a blood vessel, the method comprising:

moving a closure device through the hole and into the blood vessel, the closure device including an anchor and a sealing plug;

positioning the anchor adjacent to the hole inside the blood vessel;

positioning the sealing plug adjacent to the hole outside the blood vessel; and

compressing the sealing plug and the anchor to close the hole, wherein the sealing plug twists as the sealing plug and the anchor are compressed.

43. The method of claim 42 wherein the hole is an arteriotomy.

44. The method of claim 42 wherein moving the closure device through the hole and into the blood vessel includes inserting the closure device through an insertion sheath.

45. The method of claim 42 wherein the anchor is against the middle of the sealing plug.

46. The method of claim 42 wherein the closure device includes a filament that extends through the anchor and the sealing plug, the method comprising tensioning the filament to compress the sealing plug and the anchor and thereby close the hole.

47. The method of claim 46 wherein the filament is threaded through the sealing plug and the anchor in a manner to facilitate twisting of the sealing plug as the filament is tensioned and the sealing plug and the anchor are compressed.

48. The method of claim 46 wherein the filament extends through a first plurality of holes in the sealing plug, through the anchor, and through a second plurality of holes in the sealing plug.

49. A method of closing a hole in a blood vessel the method comprising:

moving a closure device through the hole and into the blood vessel, the closure device including a filament, an anchor, and a sealing plug, wherein the filament extends through a first plurality of holes in the sealing plug, through the anchor, and through a second plurality of holes in the sealing plug;

positioning the anchor adjacent to the hole inside the blood vessel;

positioning the sealing plug adjacent to the hole outside the blood vessel; and

tensioning the filament to compress the sealing plug and the anchor and thereby close the hole.

50. The method of claim 49 wherein the hole is an arteriotomy.

51. The method of claim 49 wherein the sealing plug includes a first portion and a second portion that are at least substantially symmetrical, the first portion including the first plurality of holes and the second portion including the second plurality of holes.

52. The method of claim 49 wherein each one of the first plurality of holes and the second plurality of holes forms a zigzag pattern.

53. A method of closing a hole in a blood vessel, the method comprising:

moving a closure device through the hole and into the blood vessel, the closure device including an anchor and a sealing plug;

positioning the anchor adjacent to the hole inside the blood vessel;

positioning the sealing plug adjacent to the hole outside the blood vessel; and

compressing the sealing plug and the anchor to close the hole, wherein the sealing plug corkscrews as the sealing plug and the anchor are compressed.

54. The method of claim 53 wherein the hole is an arteriotomy.

55. The method of claim 53 wherein the closure device includes a filament that extends through the anchor and the sealing plug, the method comprising tensioning the filament to compress the sealing plug and the anchor and thereby close the hole.

56. A method of closing a hole in a blood vessel, the method comprising:

moving a closure device through the hole and into the blood vessel, the closure device including a filament, an anchor, and a sealing plug, wherein the filament extends through the sealing plug in a spiral weave configuration;

positioning the anchor adjacent to the hole inside the blood vessel;

positioning the sealing plug adjacent to the hole outside the blood vessel; and

compressing the sealing plug and the anchor to close the hole.

57. The method of claim 56 wherein the closure device includes a filament that extends through the anchor and the sealing plug, the method comprising tensioning the filament to compress the sealing plug and the anchor and thereby close the hole.

58. A method of closing a hole in a blood vessel, the method comprising:

moving a closure device through the hole and into the blood vessel, the closure device including a filament, an anchor, and a sealing plug, wherein the filament extends through a first hole in the sealing plug, through the anchor, and through a second hole in the sealing plug, the anchor being positioned at least substantially in the middle of the sealing plug;

positioning the anchor adjacent to the hole inside the blood vessel;

positioning the sealing plug adjacent to the hole outside the blood vessel; and

tensioning the filament to compress the sealing plug and the anchor and thereby close the hole.

59. The method of claim 58 wherein the sealing plug twists as the filament is tensioned and the sealing plug and the anchor are compressed.

60. The method of claim 58 wherein the sealing plug includes a first portion and a second portion that are at least substantially symmetrical, the first portion including the first hole and the second portion including the second hole.

61. A method of closing a hole in a blood vessel, the method comprising:

moving a closure device through the hole and into the blood vessel, the closure device including an anchor and a sealing plug, wherein the sealing plug includes at least two separate components;

positioning the anchor adjacent to the hole inside the blood vessel;

positioning the sealing plug adjacent to the hole outside the blood vessel; and

compressing the sealing plug and the anchor to close the hole.

62. The method of claim 61 wherein the closure device includes a filament that extends through the anchor and through each of the at least two separate components of the sealing plug, the method comprising tensioning the filament to compress the sealing plug and the anchor and thereby close the hole.

63. The method of claim 61 wherein the at least two separate components include a first component having a U-shape and a second component having a U-shape, wherein the first component and the second component are positioned opposite each other.

64. A method of closing a hole in a blood vessel, the method comprising:

moving a closure device through the hole and into the blood vessel, the closure device including an anchor and a sealing plug, wherein at least one of the following is true regarding the sealing plug;

(a) the sealing plug has a generally V-shape when the sealing plug is open, (b) the sealing plug has a generally X-shaped cross section, (c) the sealing plug is folded to have a generally S-shape when the sealing plug is positioned in the closure device in an undeployed configuration, or (d) the sealing plug is folded latitudinally to have a generally rectangular shape when the sealing plug is positioned in the closure device in an undeployed configuration;

positioning the anchor adjacent to the hole inside the blood vessel;

positioning the sealing plug adjacent to the hole outside the blood vessel; and

compressing the sealing plug and the anchor to close the hole.

65. The method of claim 64 wherein the sealing plug twists as the sealing plug and the anchor are compressed.

66. The method of claim 64 wherein the sealing plug has a generally V-shape when the sealing plug is open.

67. The method of claim 64 wherein the sealing plug has a generally X-shaped cross section.

68. The method of claim 64 wherein the sealing plug is folded to have a generally S-shape when the sealing plug is positioned in the closure device in an undeployed configuration.

69. The method of claim 64 wherein the sealing plug is folded latitudinally to have a generally rectangular shape when the sealing plug is positioned in the closure device in an undeployed configuration.
