You can use lookahead and lookbehind.  So you could do:

     (?<=[,(] )(.*?)(?= *[,)])

The only problem with this is that lookbehind can't handle 
variable-length patterns, so you can't quite manage the pattern you 
have, with any number of spaces before the item.  But if you want, you 
can make it handle 1-4 spaces, or something, as follows:

     (?:(?<=[,(] )|(?<=[,(] {2})|(?<=[,(] {3})|(?<=[,(] {4}))
     (.*?)(?= *[,)])

Or similar.

See the documentation for more.  Oniguruma regexps are very powerful.
