ABSTRACT:
An implantable structure for incorporation into the tissues of a body is provided which retains therein fluid substances or biological substances which produce, or cause to be produced, biochemicals deliverable to the body. The implantable structure is configured to provide insertion and removal of substances therefrom as needed. The implantable structure generally comprises a porous outer member configured to encourage ingrowth of vascularized tissue therethrough, and an inner member of selectively permeable material providing interior space for inserting substances therein and which is structured to prevent ingrowth of tissue therethrough. The inner member is capable of providing immunoisolation to the substances therein as required.
