Abstract
Provided herein are elastomeric materials for use in medical devices and methods of making elastomeric materials, the elastomeric materials including a rubber composition and a phase-separating composition. Also provided herein are medical devices including elastomeric materials, the elastomeric materials including a rubber composition and a phase-separating composition.
Claims17
An elastomeric material for forming a stopper for a syringe comprising a rubber composition and a phase-separating composition, wherein the phase-separating composition migrates within the rubber composition to form a drug-absorption resistant barrier layer.
-22. (canceled)
A medical device comprising:
- a barrel defining a chamber for receiving a solution therein;
- and
- an elastomeric stopper comprising a rubber composition and a phase-separating composition, wherein the phase-separating composition is arranged at a surface of the stopper arranged to contact the solution held within the chamber.
An elastomeric material comprising:
- a rubber composition;
- and
- a phase-separating composition.
