Self-anchoring sling and introducer system
A system for supporting the urethra using an introducer needle, the ends of which are flattened and which have openings therethrough, a handle having a latch mechanism which engages the opening in the flattened portion of the first end of the introducer needle, an implant, and a connector joining the end of the implant to the flattened portion of one of the ends of the introducer needle. These components are used to draw the implant into position, either through vaginal or abdominal incisions, to form a U-shaped loop beneath the urethra. The ends of the implant are adjusted to provide proper support for the urethra. The implant can have slits that open under applied tensile force.
1. An introducer needle system configured to surgically introduce a urethral implant in a patient, comprising:
an integrally formed introducer needle including an elongated shaft connecting first and second flat spatulated sections, at least one of said spatulated sections having a tip, a constant width portion extending from the tip, and an opening formed in the constant width portion, the shaft including a straight portion connected to a curved portion, the first flat spatulated section connected to the curved portion by a flared section having a cross-sectional profile that covers a cross-sectional profile of the first flat spatulated section; and
a handle including a housing having an elongated portion with a distal end opening dimensioned to receive and hold one of said flat spatulated sections, and an elastically-based latch portion having a projection dimensioned and disposed in the housing to engage the flat spatulated section inserted into the distal end opening of the housing to secure the handle to the introducer needle.
