Surgical suturing device, method and tools used therewith

A method for remotely and subcutaneously positioning a tethering strand in tissue using a nested pair of needles coupled with a housing and an actuator coupled with the housing for longitudinal reciprocation relative to the housing, and wherein a first needle has a blunted tip and a second needle has a Sharpened tip, comprising the steps of:

• advancing the second needle relative to the first needle using the actuator so that the sharpened tip projects beyond the blunted tip;
• inserting the nested pair of needles through a surface at a first location, and making a first puncture at the first location;
• retracting the second needle using the actuator so that the blunted tip projects beyond the sharpened tip;
• passing the nested pair of needles through the first puncture and beneath the surface, to a second location spaced from the first location;
• advancing the second needle relative to the first needle using the actuator so that the sharpened tip projects beyond the blunted tip;
• and
• inserting the nested pair of needles through the surface at the second location and exiting from beneath the surface, making a second puncture at the second location.
