How to pass vArray to storedprocedure as input paramenter from Visual Basic Component?

I have to pass the following inputs
ProductName Qty
Product1 1500
Product2 2000
Product3 3500

I would like to pass a string as Varray

e.g Product1,1500,Product2,2000,Product3,3500

I don't want to parse the string inside my procedure.
Is there any simple way I can pass Varray to my SP.

I am using oracle 8i.

Thanks in Advance
