Systems, methods and devices relating to implantable supportive slings
The invention provides, in various embodiments, aspects of soft tissue anchors, adjustable length/tension slings, interconnects between slings and soft tissue anchors, delivery devices and systems for implanting supportive slings, and methods relating to anchoring, adjusting and implanting supportive slings.
1. A system for the treatment of urinary incontinence, comprising:
a sling having first and second ends;
first and second anchors, wherein the first end of the sling interfits within a slot in the first anchor, and the second end of the sling interfits within a slot in the second anchor,
each of said first and second anchors comprising a body having a proximal end, a distal end, and a through lumen extending therebetween, each of said first and second anchors further comprising at least one barb projecting radially therefrom; and
a delivery device for delivering said sling within the body of a patient, said delivery device comprising a shaft comprising a distal section that has an outer diameter that is less than a diameter of said shaft at a location immediately proximal to the distal section, wherein the distal section of said shaft is configured to extend through the through lumen of each of said first and second anchors.
2. The system of claim 1 , wherein said first and second anchors are soft tissue anchors.
3. The system of claim 1 , wherein said first and second anchors consist of a polymer material.
4. The system of claim 1 , wherein said at least one barb has a pointed tip.
5. The system of claim 1 , wherein said sling comprises tanged edges.
6. The system of claim 5 , wherein said shaft is formed substantially in a single plane.
7. The system of claim 1 , wherein said shaft comprises a straight section and a curved section distal to said straight section.
8. The system of claim 7 , wherein said straight section of said shaft has an outside diameter that is substantially constant.
9. The system of claim 1 , further comprising a shoulder at the intersection between said distal section and said location immediately proximal to said distal section.
10. The system of claim 9 , wherein each of said first and second anchors are configured to abut said shoulder during delivery thereof into the patient.
11. The system of claim 1 , wherein said sling comprises polypropylene.
12. The system of claim 1 , wherein said sling has a mesh configuration.
13. The system of claim 1 , wherein said delivery device further comprises a handle proximal to said shaft.
14. The system of claim 1 , wherein said delivery device is configured to deliver each of said first and second anchors within the patient.
15. A system for the treatment of urinary incontinence, comprising:
a mesh sling comprising polypropylene and having first and second ends;
first and second soft tissue anchors, wherein the first end of the sling interfits within a slot in the first anchor and the second end of the sling interfits within a slot in the second anchor,
each of said first and second soft tissue anchors consisting of a polymer material and comprising a body having a proximal end, a distal end, and a through lumen extending therebetween, each of said first and second soft tissue anchors further comprising at least one barb projecting radially therefrom, each of said barbs having a pointed tip; and
a delivery device for delivering said sling within the body of a patient, said delivery device comprising a shaft comprising a distal section that has an outer diameter that is less than a diameter of said shaft at a location immediately proximal to the distal section, wherein the distal section of said shaft is configured to extend through the through lumen of each of said first and second soft tissue anchors, said shaft being formed substantially in a single plane and comprising a straight section and a curved section distal to said straight section.
