This type of pattern could be solved creating a 3D curve (Helix) and patterning datum point on the curve,as I have explained below
1- Create a sphere of dia 10mm and put a datum point on the center
2- Create an assembly , and create a curve using equation
For a helix with a r=50 and a height of 200
The radius and height varies upon your need
3- Create a datum point on the curve (length ratio =0) , this is the point where you mate/assemble the part
4-Pattern the datum point , using dimension pattern . The no of items depends upon designers descretion, I have choosen 21 items at 0.05 length ratio increment.
5-Assemble the sphere coinciding the point together
6-Select the part and click the pattern icon, automatically Creo goes for reference pattern .
