1. A toothed fastener comprising:
- an upper leg and a lower leg, each of the upper and lower legs having a row of teeth, each tooth having a proximal face and a distal face;
a longitudinally extending securing member; and
a hole of predetermine diameter formed in each of the proximal and distal faces and of sufficient size to allow passage of the securing member therethrough, wherein the upper or lower legs are movable from an open position to a closed position wherein all of the holes are in longitudinal alignment enabling the securing member to pass through the holes in the teeth of the upper and lower legs to maintain the fastener in the closed position;
wherein each of the teeth are hollow and contain a material such that passage of the securing member through the holes of the teeth releases the material into the space between the upper and lower legs.

Abstract
There is provided a penetratable toothed fastener for clamping tissue during surgery. The toothed fastener includes first and second legs each having longitudinal rows of transverse teeth and a securing member configured to pass through the transverse teeth to hold first and second legs closed relative to each other and about tissue. A locking mechanism is provided to retain the securing member within the first and second legs of the toothed fastener. The toothed fastener additionally includes receptacles for the receipt of medicant materials and holes in the teeth to dispense the materials to clamped tissue.

12. A system for applying a fastener to tissue comprising:
-
an applicator having a first and a second jaw; a toothed fastener positionable within the first and second jaws, the toothed fastener including; a) an upper leg and a lower leg, each of the upper and lower legs having a row of teeth, each tooth having a proximal face and a distal face; b) a longitudinally extending securing member; and c) a hole of predetermine diameter formed in each of the proximal and distal faces and of sufficient size to allow passage of the securing member therethrough, wherein the upper and lower legs are movable from an open position to a closed position wherein all of the holes are in longitudinal alignment enabling the securing member to pass through the holes in the teeth of the upper and lower legs, wherein the first and second jaws are operable to move the upper and lower legs between the open and closed positions; and wherein each tooth has a pair of spaced apart holes formed in the proximal and distal faces and the securing member is a staple bar having a backspan and first and second legs extending distally from the backspan such that the first and second legs pass through the pairs of spaced apart holes to secure the upper and lower legs in the closed position. - View Dependent Claims (13)

14. A toothed fastener comprising:
-
an upper leg and a lower leg, each of the upper and lower legs having a row of transverse longitudinally extending teeth, each tooth having a proximal face and a distal face; a longitudinally extending securing member; and a hole of predetermine diameter formed in each of the proximal and distal faces, wherein the upper or lower legs are movable from an open position spaced apart to a closed position wherein all of the holes are in longitudinal alignment enabling the securing member to pass through the holes to maintain the fastener in the closed position; and wherein each of the teeth are hollow and contain a material such that the material is released into spaces defined between the upper and lower legs. - View Dependent Claims (15, 16, 17)
