Improved elastomeric materials useful for medical and therapeutic device applications, such as penetrable septa, are described. In one aspect, the materials are deeply cleaned with solvent to significantly lower levels of undesirable organics. In another aspect, internally lubricated elastomer compositions compatible for use in medical and therapeutic device applications are provided. The lubricating fluid is present in the composition from about 0.5% to 50% by weight, and is initially substantially homogeneously dispersed in the elastomer. The fluid can be integrated into the elastomer by a solvent infusion method. In another aspect an internally lubricated thermoplastic septum, having an appropriate hardness for resealability with multiple penetrations, is provided.
