A surgical assembly including an introducer having a handle portion and a needle portion, and at least a first retaining device extending outwardly therefrom. The assembly also includes first and second sheath elements each having a proximal end, a closed tissue penetrating distal end, a channel extending therein and a side aperture extending into the channel, and an implant having first and second ends coupled to the proximal ends of the sheath elements respectively. Channels of the first and second sheath elements are dimensioned to slidably receive therein through the side aperture the needle portion of the introducer, and for each of the first and second sheath elements when the needle portion of the introducer is so received therein, the peripheral edge of the side aperture is capable of being removably coupled to the retaining device to thereby fixedly secure the sheath element to the introducer.
