Implants, tools, and methods for treatment of pelvic conditions
View Patent ↗Described are various embodiments of surgical procedures, systems, implants, devices, tools, and methods, useful for treating pelvic conditions in a male or female, the pelvic conditions including incontinence (various forms such as fecal incontinence, stress urinary incontinence, urge incontinence, mixed incontinence, etc.), vaginal prolapse (including various forms such as enterocele, cystocele, rectocele, apical or vault prolapse, uterine descent, etc.), and other conditions caused by muscle and ligament weakness, the devices and tools including devices and tools for anchoring an implant to supportive tissue and adjusting the implant.
1. A pelvic implant useful to treat a pelvic condition, the implant comprising:
a tissue support portion, a first extension portion, and a second extension portion,
a first adjusting mechanism comprising:
a first line at the first extension portion, the first line extending between the tissue support portion and the first extension portion, the first line configured to be tightened to adjust a length of the first extension portion,
a first line holder that engages the first line at a location between the tissue support portion and the first extension portion, the first line holder configured to maintain an adjusted length of the first extension portion,
a first tab,
a first tether having a first end portion and a second end portion, the first end portion of the first tether being securely attached to the first line holder, the second end portion of the first tether being coupled to the first tab, wherein pulling the first tab which is configured to move the first line holder along the first line in a direction toward the tissue support portion reduces a first distance between the first extension portion and the tissue support portion,
a second adjusting mechanism comprising:
a second line at the second extension portion, the second line configured to be tightened to adjust a length of the second extension portion,
a second line holder that engages the second line at a location between the tissue support portion and the second extension portion, the second line holder is configured to maintain an adjusted length of the second extension portion,
a first self-fixating tip disposed at a distal end of the first extension portion, and
a second self-fixating tip disposed at a distal end of the second extension portion.
2. The implant as recited at claim 1 , comprising:
a tissue support portion piece comprising the tissue support portion, a first end, and a second end,
a first extension portion piece comprising the first extension portion, a proximal end, and the distal end of the first extension portion,
a second extension portion piece comprising the second extension portion, a proximal end, and the distal end of the second extension portion,
wherein the first line connects the proximal end of the first extension portion piece and the first end of the tissue support portion piece, and
the second line connects the proximal end of the second extension portion piece and the second end of the tissue support portion piece.
3. The implant as recited at claim 1 , wherein the implant has a length to allow the first and second self-fixating tips to be placed at tissue of opposing obturator foramen of a patient, with the tissue support portion supporting tissue of a urethra or an anus.
4. The implant as recited at claim 1 , wherein the first line is coupled to a first end of the tissue support portion, the first line extending through the first line holder and through an aperture at a proximal end of the first extension portion, the first line being coupled to the first line holder.
5. The implant as recited at claim 1 , wherein, with the first line under tension, the first line holder is configured to prevent the distance between the first extension portion and the tissue support portion from increasing.
6. The implant as recited at claim 1 ,
wherein the first line is coupled to a first end of the tissue support portion, the first line extending through the first line holder and through an aperture at a proximal end of the first extension portion, the first line being coupled to the first line holder, and
wherein the second line is coupled to a second end of the tissue support portion, the second line extending through the second line holder and through an aperture at a proximal end of the second extension portion, the second line being coupled to the second line holder.
7. The implant as recited at claim 1 , further comprising a second tab, and a second tether having a first end portion and a second end portion, the first end portion of the second tether securely coupled to the second line holder, the second end portion of the second tether being coupled to the second tab.
8. The implant as recited at claim 7 , wherein pulling the second tab is configured to move the second line holder along the second line in a direction toward the tissue support portion to reduce a second distance between the second extension portion and the tissue support portion.
9. The implant as recited at claim 8 , wherein, with the second line under tension, the second line holder is configured to prevent the second distance from increasing.
10. The implant as recited at claim 1 , wherein, with the implant placed within a patient with the first and second self-fixating tips at tissue of opposing obturator foramen and the tissue support portion supporting tissue of a urethra or an anus, each of the first tether and the second tether is configured to be accessed through a medial incision of the patient to actuate each of the first and second adjusting mechanisms.
11. The implant as recited at claim 1 , wherein
the first line comprises a flexible tube that is coupled to a first end of the tissue support portion and the flexible tube extends through an aperture at a proximal end of the first extension portion,
the first adjusting mechanism comprises an elongate member, the elongate member moveably extending through the flexible tube, the first line holder being secured to a distal end of the elongate member, the first line holder having a dimension larger than the aperture,
pulling the first line reduces the first distance between the first extension portion and the tissue support portion, and
pulling the elongate member causes the first line holder to engage the aperture to prevent the first distance from increasing.
12. The implant as recited at claim 1 , wherein the first line holder comprises an elastomeric body configured to be deformed upon contact with the first line under tension.
13. A method of treating a pelvic condition, the method comprising:
providing the implant as recited at claim 1 ,
placing the implant in a patient to support pelvic tissue,
actuating the first adjusting mechanism to adjust the length of the first extension portion.
14. The method as recited at claim 13 , further comprising actuating the second adjusting mechanism to adjust the length of the second extension portion.
15. The method as recited at claim 13 , wherein the pelvic condition is selected from the group consisting of: fecal incontinence and urinary incontinence.
16. The method as recited at claim 13 for treating urinary incontinence, the method comprising:
creating a medial incision in the patient,
placing the tissue support portion to contact tissue to support the urethra,
placing a distal end of the first extension portion in a tissue path extending toward a first obturator foramen of the patient, and
placing a distal end of the second extension portion in a tissue path extending toward a second obturator foramen of the patient.
