Stumped by reg. expressions

[twistedm1nd]

I have a string which has to be grouped using regular expressions
The sample string is
\{Voltage\}{VoltageValue, Max\{Value\},5,5}\{Voltage\}\{Pressure\}{PressureValue,12345}\{Pressure\}
The output should be

Group 1 : {VoltageValue, Max\{Value\},5,5}
Group 2 : {PressureValue,12345}

Basically should ignore "\{", "\}" and group it based on { and }
Can Somebody help me in formulating the regular expression?

Thanks and regards
