Suture securing device and method

Claim 2

A suture securing method comprising: (a) providing a suture; (b) providing a suture securing device that includes a body having a tissue abutting side, a suture loop side, and a passage having a selected diameter extending therebetween, said passage having open ends at said tissue abutting side and at said suture loop side; (c) passing a loop of suture through said passage from said open end at said tissue abutting side through said open end at said suture loop side; (d) passing a free end of said suture about said body and through said loop, and drawing taut the free end of the suture that has been passed through said loop; (e) pushing said body along the suture away from the free end to a desired position, said selected diameter of said passage being sufficient to allow the suture to slide in said passage as said body moves along the suture to said desired position; and (f) applying tension to the suture when said body is in said desired position to retract a portion of said loop and the portion of the suture which passes through said loop into said passage, thereby to clamp said portion of the suture within said passage.

Claim 3

The method of claim 1 wherein said body has an outer peripheral surface that includes a suture accommodating channel having a depth and a width greater than a thickness of the suture so that the suture is recessed with respect to said outer peripheral surface when placed in said channel and can freely move within said channel during said pushing step.

Claim 4

The method of claim 1 wherein at least said open end at said tissue abutting side is enlarged with respect to said selected diameter to receive the retracted portion of said loop and the portion of the suture that passes through the loop.

Claim 5

Apparatus comprising: a suture; a suture securing device that includes a surgically implantable body having a tissue abutting side, a suture loop side, and a passage having a selected diameter disposed through said body, said passage having open ends at said tissue abutting side and at said suture loop side, said open end at said suture loop side being enlarged with respect to said selected diameter; the suture having two ends and a loop therebetween, the suture passing from said tissue abutting side, through said passage to said suture loop side and back through said passage to said tissue abutting side such that the loop emerges from said open end of said passage at said suture loop side, and a first one of said ends passing about said body and through said loop; said selected diameter of said passage being sufficient to allow said body to be pushed along the suture away from said first end to a desired position with respect to a second one of said ends, with the suture sliding in said passage as said body moves along the suture to said desired position.

Claim 6

Apparatus comprising: a suture; a suture securing device that includes a surgically implantable body having a tissue abutting side, a suture loop side, and a passage having a selected diameter disposed through said body, said passage having open ends at said tissue abutting side and at said suture loop side, said open end at said suture loop side being enlarged with respect to said selected diameter; the suture having two ends and a loop therebetween, the suture passing from said tissue abutting side, through said passage to said suture loop side and back through said passage to said tissue abutting side such that the loop emerges from said open end of said passage at said suture loop side, and a first one of said ends passing about said body and through said loop; said selected diameter of said passage being sufficient to allow said body to be pushed along the suture away from said first end to a desired position with respect to a second one of said ends, with the suture sliding in said passage as said body moves along the suture to said desired position.

Claim 7

The apparatus of claim 4 wherein said body has an outer peripheral surface that includes a suture accommodating channel having a depth and a width greater than a thickness of the suture so that the suture is recessed with respect to said outer peripheral surface when placed in said channel and can freely move within said channel during said pushing step.

Claim 8

The apparatus of claim 5 wherein said channel extends substantially parallel to said passage.

Claim 9

The apparatus according to claim 4 wherein said enlarged open end comprises a counter-bore of said passage.

Claim 10

The apparatus according to claim 4 wherein one of said free ends of said suture has a suturing needle connected therewith.

Claim 11

Apparatus for intracorporeally securing a suture, comprising: a suture; a surgically implantable body having a tissue abutting side, a suture loop side, and a passage extending therebetween, said passage having open ends at said tissue abutting side and at said suture loop side, at least said open end at said suture loop side being enlarged with respect to a diameter of said passage; the suture having two ends and a loop therebetween, the suture passing from said tissue abutting side, through said passage to said tissue abutting side such that the loop emerges from said enlarged open end of said passage on said suture loop side, and a first one of said ends passing about said body and through said loop; said diameter of said passage being sufficient to allow said body to be pushed along the suture away from said first end to a desired position with respect to a second one of said ends, with the suture sliding in said passage as said body moves along the suture to said desired position; and said enlarged open end of said passage being configured to allow a portion of said loop and the portion of the suture which passes through said loop to be retraced through said enlarged open end into said passage.

Claim 12

Apparatus for intracorporeally securing a suture, comprising: a suture; a surgically implantable body having a tissue abutting side, a suture loop side, and a passage extending therebetween, said passage having open ends at said tissue abutting side and at said suture loop side, at least said open end at said suture loop side being enlarged with respect to a diameter of said passage; the suture having two ends and a loop therebetween, the suture passing from said tissue abutting side, through said passage to said tissue abutting side such that the loop emerges from said enlarged open end of said passage on said suture loop side, and a first one of said ends passing about said body and through said loop; said diameter of said passage being sufficient to allow said body to be pushed along the suture away from said first end to a desired position with respect to a second one of said ends, with the suture sliding in said passage as said body moves along the suture to said desired position; and said enlarged open end of said passage being configured to allow a portion of said loop and the portion of the suture which passes through said loop to be retraced through said enlarged open end into said passage.

Claim 13

The apparatus of claim 9 wherein said body has an outer peripheral surface that includes a channel positioned to receive a portion of a free end of the suture that is passed about said body and through said loop, said channel having a depth and a width greater than a thickness of the suture so that said portion of the suture is recessed with respect to said outer peripheral surface and can freely move within said channel, thereby to allow said body to be gripped at said outer peripheral surface and pushed along the suture.

Claim 14

The apparatus according to claim 10 wherein said channel extends substantially parallel to said passage.

Claim 15

The apparatus according to claim 10 wherein said outer peripheral surface includes locating portions thereon to provide surfaces adapted to be gripped to push the body along the suture to the desired position.

Claim 16

The apparatus according to claim 12 wherein said body is substantially rectangular in shape having two side walls longer in length than two end walls, and said locating portions include a recess at each end wall of the implantable body between the tissue abutting side and the suture loop side.

Claim 17

The apparatus according to claim 9 wherein external surfaces of said body are radiussed.

Claim 18

The apparatus according to claim 9 wherein said loop is drawable from the tissue abutting side to the suture loop side but not from the suture loop side to the tissue abutting side.
