  • Controlled release matrix barrier structure for subcutaneous medical devices
    Patent number: 9993441
    Abstract: A biocompatible polymeric controlled release matrix barrier structure for delivery of one or more bioactive agents from an implantable medical device is described. In an embodiment, a biocompatible polymeric controlled release matrix barrier structure is included. The biocompatible polymeric controlled release matrix can include a body structure formed of a compliant material comprising one or more compliant biocompatible polymers and one or more bioactive agents. The body structure can define a central aperture through which a subcutaneous element of an implantable medical device passes. Other embodiments are included herein.
