Burr removal apparatus

A burr removal apparatus, comprising:

• an elongate working shaft having proximal and distal end portions;
• an abrasive mechanism disposed along said distal end portion of said working shaft, said abrasive mechanism having a diameter greater than at least a portion of said working shaft;
• and
• a non-abrasive member having a diameter greater than at least a portion of said abrasive mechanism.

A method for removing a burr from an edge of a workpiece, comprising:

• providing an elongate access device having a distal end portion;
• providing an abrasive mechanism along said distal end portion of said access device, said abrasive mechanism including an abrasive material that can abrade said edge of said workpiece, said abrasive mechanism having a diameter greater than said access device;
• providing a non-abrasive member along said distal end portion of said access device that will not substantially abrade said workpiece, said non-abrasive member having a diameter greater than said abrasive mechanism;
• rotating said access device relative to said workpiece;
• advancing said burr removal apparatus along a wall of said workpiece wherein said non-abrasive member engages said wall until said non-abrasive member is advanced distally of said edge of said workpiece such that said abrasive mechanism contacts said edge;
• and
• removing at least one burr by abrading said edge through contact with said abrasive mechanism.
