How to type bold parentheses in math mode?

Question

How can I write bold/very bold parentheses?

I'm using:

\documentclass[journal]{IEEEtran} 
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{breqn}
\newtheorem{lemma}{Lemma}   
\begin{document}
\begin{dmath}
\left( something \right)
\end{document}

However, I want the \left( and \right) to appear bold.

Thanks

\begin{dmath}
\left( something  \right)
\end{dmath}

\end{dmath}
