Actuation sled having a curved guide member and method

A method comprising:

• injecting a polymer into a mold so as to form a guide member for the sled product, the mold being shaped so that:
• (i) the guide member has a proximal end and a distal end, the proximal and distal ends having a first width;
• (ii) the guide member has a single, centrally disposed portion between the proximal and distal ends, the centrally disposed portion further including at least one shaped portion;
• (iii) the shaped portion having a sloping, non-linear surface;
• (iv) wherein the centrally disposed portion has a second width different than the first width of the proximal and distal ends of the guide member;
• and
• (v) wherein the at least one shaped portion includes a first camming member and a second camming member, the first and second camming members each having spaced apart first and second cam wedges, each of the cam wedges including at least first and second drive faces configured to define first and second drive angles with respect to a base portion of the sled product.
