1. A delivery device for transtendinous implantation of a toggle-type suture anchor into bone, the device comprising:
a handle assembly including a housing having a proximal end and a distal end, with an outer tubular shaft extending distally from the housing and having a lumen therethrough;
an anchor delivery tube having a distal nub portion, the delivery tube slidably disposed within the lumen of the outer tubular shaft and having a proximal end terminating within the housing, the anchor delivery tube and distal nub portion having a lumen therethrough;
means for selectively moving the anchor delivery tube between a first extended position with the nub projecting beyond the outer tubular shaft and a second retracted position with the nub withdrawn into the outer tubular shaft; and
a bone punch assembly having a proximal end and a distal end with a pointed tip, the bone punch assembly configurable to move between:
a fully inserted configuration in which the bone punch assembly passes through the lumen of the anchor delivery tube such that the pointed tip extends beyond the nub portion while the proximal end of the bone punch assembly is attached to the proximal end of the housing, and
a fully retracted configuration in which the pointed distal end is withdrawn proximally of the distal end of the nub portion and the proximal end of the bone punch assembly is detached from the proximal end of the housing.
