There's completely no way to delete them permanently, in normal way. But i don't know if there's a way, but you might need to ROOT your phone.

Secure Delete might work.

I've never used it, but it seems to claim what you want. Now, how effective it is, I don't know. Forensic file recovery can be pretty fancy-schmancy these days.
