Pelvic implant system and method
View Patent ↗Systems and methods are provided and adapted to engage and pull (e.g., pull up) or reposition urethral support tissue, such as the portion of the perineal membrane above or below the urethra. The perineal membrane intersects the urethra and vagina at the midurethra or distal location and can thus be stabilized or controlled in a manner that helps restore continence.
1. A urethral support system for treating incontinence in a patient, comprising:
an elongate first implant device having a first end and a second end, the first implant device having a first medial device having a medial width and provided at the first end of the first implant device and adapted to anchor into a portion of the perineal membrane above the urethra of the patient and not below the urethra, the first medial device having a first anchor portion, a second anchor portion, and an aperture disposed between the first anchor portion and the second anchor portion, the first implant device having a first suture configured to extend through the aperture, and a first distal anchor device provided at the second end of the first implant device and operatively connected to the first medial device via the first suture, at least the medial width of the first medial device being larger than a width of the first suture, the first distal anchor device adapted to engage tissue distal to the perineal membrane;
an elongate second implant device, physically separate from and unconnected to the first implant device, having a first end and a second end, the second implant device having a second medial device provided at the first end of the second implant device and adapted to anchor into a portion of the perineal membrane above, and not below, the urethra of the patient spaced away from the first implant device, the second medial device having a first anchor portion, a second anchor portion, and an aperture disposed between the first anchor portion of the second medial device and the second anchor portion of the second medial device, the second implant device having a second suture configured to extend through the aperture of the second medial device, and a second distal anchor device provided at the second end of the second implant device and operatively connected to the second medial device via the second suture, the second distal anchor device adapted to engage tissue distal to the perineal membrane.
2. The system of claim 1 , wherein the first distal anchor device includes a first array of anchors, each of the first array of anchors having expandable barbs.
3. The system of claim 1 , wherein the first anchor portion of the first medial device includes one or more first barbs, and the second anchor portion of the first medial device includes one or more second barbs.
4. The system of claim 1 , wherein the first distal anchor device of the first implant device is adapted to engage a target tissue site selected from the group consisting of: the obturator foramen, obturator intemus, abdominal fascia, sacrospinous ligament, prepubic fascia, rectus fascia, the tendinous arch of the levator ani, the Cooper's ligament, and the pubic symphysis cartilage.
5. The system of claim 1 , wherein the first medial device of the first implant device is a mesh device.
6. The system of claim 1 , wherein the first medial device of the first implant device is a plate device.
7. The system of claim 1 , wherein the first medial device of the first implant device is a toggle tissue anchor device.
8. The system of claim 1 , wherein the first medial device of the first implant device is at least partially flexible.
9. The system of claim 1 , wherein the first medial device of the first implant device is at least partially rigid.
10. A urethral support system for treating incontinence in a patient, comprising:
an elongate first implant device having a first end and a second end, the first implant device having a first medial device provided at the first end of the first implant device and adapted to anchor into a portion of and span across a portion of the perineal membrane adjacent the urethra of the patient, the first medial device having a first anchor portion, a second anchor portion, and an aperture disposed between the first anchor portion and the second anchor portion, the first implant device having a first suture configured to extend through the aperture, the first suture having a first end portion and a second end portion, the first implant device including a first distal anchor device provided at the second end of the first implant device, the first distal anchor device being coupled to the first end portion of the first suture, the first distal anchor device adapted to engage tissue superior to the perineal membrane;
an elongate second implant device, not connected to and physically separate and spaced from the first implant device, having a first end and a second end, the second implant device having a second medial device provided at the first end of the second implant device and adapted to anchor into a portion of and span across a portion of the perineal membrane adjacent the urethra of the patient spaced away from the first implant device, the second medial device having a first anchor portion, a second anchor portion, and an aperture disposed between the first anchor portion of the second medial device and the second anchor portion of the second medial device, the second implant device having a second suture configured to extend through the aperture of the second medial device, the second suture having a first end portion and a second end portion, the second implant device including a distal anchor device provided at the second end of the second implant device, the second distal anchor device being coupled to the first end portion of the second suture, the second distal anchor device adapted to engage tissue superior to the perineal membrane.
11. The system of claim 10 , wherein the second distal anchor device includes a first array of anchors, each of the first array of anchors having expandable barbs.
12. The system of claim 10 , further including:
a first suture lock coupled to the second end portion of the first suture; and
a second suture lock coupled to the second end portion of the second suture.
13. The system of claim 10 , wherein the first distal anchor device of the first implant device is adapted to engage a target tissue site selected from the group consisting of: the obturator foramen, obturator intemus, abdominal fascia, sacrospinous ligament, prepubic fascia, rectus fascia, the tendinous arch of the levator ani, the Cooper's ligament, and the pubic symphysis cartilage.
