Abstract: A needle assembly for passing suture within the body includes a rigid needle having a proximal end and a pointed distal end, and an opening in the distal end extending through the needle for retaining a suture therein; a stop element positioned on the needle proximate to, and spaced from, the proximal end of the needle; a sheath having a lengthwise bore therethrough for slidably retaining the needle; and a lock member engageable with the needle stop element to prevent distal movement of the needle in the sheath bore. The needle distal end is movable to an exposed position for passing the assembly through tissue, and is movable to a shielded position within the sheath for passing the assembly safely past the tissue which is not to be penetrated. There is further contemplated a method for passing suture within the body, using the needle assembly.

Abstract: A fastener for binding a layer of mammalian soft tissue to a mammalian bone includes a body portion for disposition in a bore in the bone, the body portion having means thereon for resisting movement of the body portion from the bore. The fastener further includes gripper portions extending from the body portion and extendible through the layer of tissue toward the bone to bind the tissue to the bone. The invention further contemplates a method for making the fastener, a method for binding layers of material together using the fastener, a tool for setting the fastener, and tools and fasteners in combination.
