There are no ways to recover from deleted VMFS volumes, you may want to call VMware support and see if they have a method.

As of ESX 3.5u3 there is a utility called vmfs-unelete which creates a block list which can be used later to help restore if you were to delete but without that blocklist it'll be quite difficult. I'm sure it's not impossible but may require VMware support or lots of $$$ (I know we had search around the web and VMFS recovery can be in excess of $2k+) This utility seemed to have been short lived and only exists in u3 and it might be in u4 but definitely not in vSphere ESX 4.0.
You may want to double check that the VMs are actually running and that they're accessible, if they are actually running then you did not delete them. Little confused by your comment
