CRIMPING INSTRUMENT WITH REDUCED DIMENSION, CONTINUED COMPATIBILITY, AND TISSUE PROTECTION FEATURES
First Claim
1. An instrument for crimping a suture fastener to a surgical suture, the instrument comprising:
- a shaft;
an expanded receiving face configured to receive the suture fastener and to provide a smoothing radius for a distal end of the shaft;
an anvil in the distal end of the shaft;
a hammer in the distal end of the shaft and moveable relative to the anvil for crimping the suture fastener therebetween and received in the expanded receiving face; and
a pusher moveable in a direction substantially parallel to a longitudinal axis of the shaft and configured to engage at least one of the hammer and the anvil for urging the hammer and the anvil together.

Abstract
An instrument for crimping a suture fastener to a surgical suture is disclosed. The instrument has a shaft and an expanded receiving face configured to receive the suture fastener and to provide a smoothing radius for a distal end of the shaft. The instrument also has an anvil in the distal end of the shaft. The instrument further has a hammer in the distal end of the shaft and moveable relative to the anvil for crimping the suture fastener therebetween and received in the expanded receiving face. The instrument also has a pusher moveable in a direction substantially parallel to a longitudinal axis of the shaft and configured to engage at least one of the hammer and the anvil for urging the hammer and the anvil together.

21. An instrument for crimping a suture fastener to a surgical suture, the instrument comprising:
-
a) a shaft; b) a crimping member coupled to a distal end of the shaft and comprising first and second opposed legs; c) an anvil located near the end of the second opposed leg; d) an expanded receiving face coupled to the anvil, the expanded receiving face; 1) configured to receive the suture fastener and to provide a smoothing radius for a distal end of the shaft; and 2) comprising a collar recess configured to hold a collar of the suture fastener; e) a hammer near the end of the first opposed leg and moveable relative to the anvil for crimping the suture fastener therebetween and received in the expanded receiving face; f) a pusher moveable in a direction substantially parallel to a longitudinal axis of the shaft and configured to engage the hammer for urging the hammer towards the anvil; g) a suture cutting blade coupled to the pusher; and h) wherein; 1) the crimping member comprises one or more blade steering guides; and 2) the first opposed leg comprises a flexure.
