View Patent ↗Surgical articles that are conveniently and securely coupled are disclosed. Improved surgical procedures are also disclosed.
1. A system for treating incontinence, comprising:
an elongate needle having a distal tip portion including a recessed keying feature, the elongate needle sized and shaped for insertion through a vaginal incision such that at least the distal tip portion is emergable from at least one other incision;
a sling for implantation in the body during a procedure to treat incontinence; and
a coupler having a longitudinal axis, the coupler having an exterior wall and at least one generally circular relief port extending into the exterior wall of the coupler generally transverse to the longitudinal axis, with an interior shoulder extending from the exterior wall to define a narrowed gap within the coupler, the interior shoulder adapted to snappingly connect the coupler to the recessed keying feature of the needle by moving the coupler and the recessed keying feature of the needle together along the longitudinal axis of the coupler.
2. The system of claim 1 , wherein the coupler is provided with the sling.
3. The system of claim 2 , wherein the coupler is integrally provided with the sling.
4. The system of claim 1 , wherein the system has an Insertion Force of no more than about eight pounds.
5. The system of claim 1 , wherein the system has an Insertion Force of no more than about fifteen pounds.
6. The system of claim 1 , wherein the sling includes an insertion sheath and a portion of the coupler is attached to the sheath.
7. The system of claim 1 , wherein the distal tip portion of the needle is substantially blunt.
8. The system of claim 1 , wherein the sling is constructed of a mesh material.
9. The system of claim 1 , wherein a tip portion of the coupler is substantially blunt.
10. The system of claim 1 , wherein a tip portion of the coupler is generally tapered.
11. The system of claim 1 , wherein a portion of the needle is curved.
12. A system for treating incontinence, comprising:
an elongate curved needle having a distal tip portion having a recessed keying feature, the elongate needle sized and shaped for initial insertion through a vaginal incision such that at least the distal tip portion is emergable from at least one other incision;
a mesh sling for implantation in the body during a procedure to treat incontinence; and
a coupler having an interior lumen, a cylindrical exterior wall portion, a generally circular relief port extending generally transversely into the coupler, and an interior shoulder portion extending from the exterior wall portion to define a narrowed gap within the interior lumen of the coupler, the shoulder portion adapted to provide a snap connection between the coupler and the recessed keying feature of the needle when the coupler and the recessed keying feature are longitudinally moved together.
13. The system of claim 12 , wherein the coupler is integrally provided with the sling.
14. The system of claim 12 , wherein the sling includes an insertion sheath and a portion of the coupler is attached to the sheath.
15. The system of claim 12 , wherein a tip portion of the coupler is generally tapered.
