Claim:
1. A knot placement device comprising: a handle having proximal and distal ends, the proximal end of the handle defining a proximal most end of the knot placement device; an elongate shaft with proximal and distal ends and a lumen extending therethrough, the proximal end of said shaft directly coupled to said handle, the distal end of the handle located closer to the proximal end of said shaft than to the distal end of said shaft throughout use of the knot placement device, the elongate shaft further comprising a single continuous wall from the proximal end to the distal end with a side hole near its distal end and spaced proximal from the distal end; a push rod having proximal and distal ends slidably disposed in the lumen of said elongate shaft, the proximal end of said push rod extending into said handle; an actuator located on said handle, wherein activating said actuator distally advances said push rod relative to said elongate shaft; and a knot comprising a knot body and a plug, said knot positioned in the lumen of the elongate shaft at the distal end thereof, at least a portion of the knot body surrounded circumferentially and continuously by a portion of the elongate shaft distal of the side hole; wherein at least one of the knot body and the plug is configured to receive at least one suture portion extending into the lumen of the elongate shaft at the distal end with the at least one suture portion exiting the shaft through the side hole; wherein distal advancement of the push rod moves the plug relatively into the knot body to secure the at least one suture portion, and further distal advancement of the push rod causes the knot to eject from the lumen of the shaft.
