Adjustable sling and method of treating pelvic conditions
View Patent ↗Systems for providing support within the pelvic region of a patient. The systems can include an elongated incontinence sling having a central support portion adapted to be positioned to support any one of the urethra or anus, and a sling tension adjustment mechanism operatively attached to the elongated sling. The sling tension adjustment mechanism can include a plunger device adapted for traversal within an interior of the housing, and an inflatable bladder provided within the housing to selectively control traversal of the plunger. Alternatively, the adjustment mechanism can include a bobbin device within the housing and one or more retention devices to selectively restrict unwinding of a suture from the bobbin device.
1. A system to alleviate incontinence, comprising:
an elongated incontinence sling including a central support member adapted to be positioned to support a urethra or an anus, a first sling end member, and a second sling end member, the central support member being separated from a terminal end of the first sling end member by a first adjustment gap, the central support member being separated from the first sling end member by a first distance, the central support member being separated from a terminal end of the second sling end member by a second adjustment gap, the central support member being separated from the second sling end member by a second distance, the central support member, the first sling end member, and the second sling end member being physically separate mesh constructs;
one or more first tension members coupled to the central support member and the first sling end member, the one or more first tension members extending across the first adjustment gap to provide selective tensioning adjustment, the one or more first tension members includes two or more first tension members; and
one or more second tension members coupled to the central support member and the second sling end member, the one or more second tension members extending across the second adjustment gap to provide selective tensioning adjustment.
2. The system of claim 1 , further comprising at least one tissue anchor coupled to at least one of the first and second sling end members and adapted to be passed through the body tissue.
3. The system of claim 1 , wherein the two or more first tension members include suture members.
4. The system of claim 1 , wherein the one or more second tension members include one or more suture members.
5. The system of claim 1 , wherein the one or more second tension members includes two or more second tension members.
6. The system of claim 1 , wherein the first sling end member includes a first tissue anchor, and the one or more first tension members extend from the central support member, across the first adjustment gap, along the first sling end member, and are coupled to the first tissue anchor.
7. The system of claim 1 , wherein the second sling end member includes a second tissue anchor, and the one or more second tension members extend from the central support member, across the second adjustment gap, along the second sling end member, and are coupled to the second tissue anchor.
8. A system for providing support to body tissue to alleviate incontinence, comprising:
an elongated incontinence sling including a central support member adapted to be positioned to support a urethra or an anus, a first sling end member, and a second sling end member, the central support member, the first sling end member, and the second sling end member being physically separate mesh constructs, the central support member being separated from a terminal end of the first sling end member by a first adjustment gap, the central support member being separated from the first sling end member by a first distance, the central support member being separated from a terminal end of the second sling end member by a second adjustment gap, the central support member being separated from the second sling end member by a second distance;
a first tissue anchor coupled to the first sling end member;
a second tissue anchor coupled to the second sling end member;
at least two first tension members coupled to the central support member and the first sling end member, the at least two first tension members extending across the first adjustment gap to provide selective tensioning adjustment; and
at least two second tension members coupled to the central support member and the second sling end member, the at least two second tension members extending across the second adjustment gap to provide selective tensioning adjustment.
9. The system of claim 8 , wherein the at least two first tension members include at least two suture members.
10. The system of claim 8 , wherein the at least two second tension members include at least two suture members.
11. The system of claim 8 , wherein the at least two first tension members extend from the central support member, across the first adjustment gap, along the first sling end member, and are coupled to the first tissue anchor.
12. The system of claim 11 , wherein the at least two second tension members extend from the central support member, across the second adjustment gap, along the second sling end member, and are coupled to the second tissue anchor.
