Delivery device for implanting knotless micro-suture anchors and anchor arrays for attachment of soft tissue to bone

A delivery device for transtendinous implantation of a toggle-type suture anchor into bone, the device comprising:

• a handle assembly including an outer tubular shaft affixed thereto and extending distally with a lumen therethrough;
• an anchor delivery tube slidably extending through the lumen of the outer tubular shaft having a distal end terminating in a nub portion and a proximal end connected to means for sliding the anchor delivery tube between a first retracted position with the nub portion inside the outer tubular shaft and a second distally extended position with the nub portion projecting beyond the end of the outer tubular shaft;
• and
• an anchor loading chamber in communication with the proximal end of the anchor delivery tube for receiving a toggle-type anchor therein.

A delivery device for transtendinous implantation of a toggle-type suture anchor into bone, the device comprising:

• a proximal housing including an elongate tube extending distally therefrom with a lumen therethrough, the proximal housing including a handle, a trigger and a slot for receiving the toggle-type suture anchor;
• an anchor delivery tube extending through the lumen of the elongate tube and having a proximal end in the proximal housing, the anchor delivery tube ending in a nub portion, wherein the anchor delivery tube is moveable relative to the proximal housing and elongate tube to selectively extend or retract the nub portion from a distal end of the elongate tube wherein the proximal housing contains means for selectively positioning the nub portion in a first retracted position or a second extended position;
• and
• a magazine carrying cartridges and each cartridge carrying an anchor therein, the anchor pre-strung along a working suture with the delivery device having a mating surface for removable attachment of the magazine to the proximal housing.
