Abstract
A delivery device for transtendinous implantation of a toggle-type suture anchor into bone is disclosed. The device includes a proximal housing having an outer tubular shaft extending distally with a lumen therethrough. An anchor delivery tube extends through the lumen of the outer tubular shaft having a proximal end affixed to the proximal housing. The anchor delivery tube includes a nub portion that is used to insert through the tendon and partly into bone to maintain registration with a bone hole into which an anchor is placed. A bone punch assembly extends through the lumen of the anchor delivery tube and the nub portion with a pointed distal end. When the bone punch is fully inserted, the pointed distal end extends a distance distal of the distal end of the nub portion.
