Adjustable implant
An implantable support member having at least one adjusting portion operable for adjusting a length or tension of the support member after placement of support member anchors. The support member is operable to provide mid-urethral support for treating urinary incontinence.
1. An adjustable implant, in an assembled state, comprising:
a support member formed of mesh;
a first anchor inserted through the mesh of the support member approximate a first end of the support member;
an arm formed of mesh and extending from a second end of the support member;
a second anchor having an aperture through which the mesh of the arm passes; and
an adjusting suture having a locking end, a looped portion, and an adjusting portion, the locking end of the adjusting suture attached directly to the mesh of the second end of the support member, the looped portion of the adjusting suture passing directly through an eyelet in the second anchor, and a portion of the adjusting portion of the adjusting suture surrounded by a tubing, the adjusting suture having a sliding locking knot formed at an intersection of the locking end, the looped portion, and the adjusting portion of the adjusting suture, the sliding locking knot configured to provide for a reduction in a length between the second end of the support member and the second anchor and to substantially prevent an expansion of said length.
2. The adjustable implant of claim 1 wherein the aperture of the second anchor is configured such that the arm reversibly slides through the aperture.
3. The adjustable implant of claim 1 wherein said arm is unitary with the support member.
4. The adjustable implant of claim 1 wherein the sliding locking knot is positioned between the first and second anchors.
5. An adjustable implant, in an assembled state, comprising:
a support member formed of mesh;
a first anchor inserted through the mesh of the support member approximate a first end of the support member;
an adjusting suture having a locking end, a looped portion, and an adjusting portion, the locking end of the adjusting suture attached directly to the mesh of a second end of the support member;
a second anchor having an eyelet through which a looped portion of the adjusting suture passes; and
a sliding locking knot formed at an intersection of the locking end, the looped portion, and an adjusting portion of the adjusting suture, the sliding locking knot configured to allow a reduction in size of the looped portion of the adjusting suture and to substantially prevent an expansion in size of the looped portion of the adjusting suture; and
a tubing surrounding a portion of the adjusting portion of the adjusting suture.
6. The adjustable implant of claim 5 wherein the adjusting suture is reversibly slideable through the eyelet of the second anchor.
7. The adjustable implant of claim 5 wherein the sliding locking knot comprises a knot selected from a group consisting of: an SMC knot, a Western knot, a Giant knot, and a Snyder knot.
8. The adjustable implant of claim 5 further comprising a tab attached to an end of the adjusting portion of the adjusting suture.
9. The adjustable implant of claim 5 wherein the support member comprises an arm extending from the second end of the support member.
10. The adjustable implant of claim 9 wherein said arm is unitary with the support member.
11. The adjustable implant of claim 9 wherein the second anchor comprises an aperture reversibly slideable over the arm.
