collet cage 202 to ensure the concentricity of plug 262 when advanced distally into ring 260 one approach is to establish a reduced diameter portion in the proximal end of collet cage 202 to receive and maintain plug 262 in alignment with ring 260 in an alternate embodiment shown in fig2 25 a generally cylindrical bushing 205 is provided in the proximal end of collet cage 202 to reduce the complexity of the geometry of the inner walls of collet cage 202 bushing 205 is adapted to allow for the free axial movement of plug 262 within collet cage 202 the overall configuration of the suture clip delivery device is shown in fig2 and 27 a control handle 270 is attached to a proximal end of a collet cage tube 271 that may be in the form of a hypotube a distal end of tube 271 is attached to the proximal end of collet cage 202 tube 271 has an inner diameter that is adapted to receive clip pusher 230 that slides freely within tube 271 to operate the working features of the delivery device two control surfaces are provided for advancing and retracting the various sliding components the first clip pusher handle 232 is attached to the proximal end of clip pusher 230 the second is sliding sleeve handle 274 which is attached to a proximal end of a sliding sleeve tube 276 the distal end of which comprises sliding sleeve 220 sliding sleeve tube 276 may be in the form of a hypotube with an inner diameter dimensioned to receive collet cage tube 271 that slides freely within sliding sleeve tube 276 clip pusher 230 collet cage tube 271 and sliding sleeve tube 276 are all coaxially arranged to allow the system to be dimensioned.
