Abstract
Abstract Disclosed is an implantable device for delivering a pre-selected molecule, for example, a hormone, into a mammal's systemic circulation. The device comprises a blood permeable element that can be anchored to an inner wall of an intact blood vessel. The device also comprises a capsule that is held in place within the blood vessel by the anchored blood permeable element. The capsule encloses viable cells which produce and secrete the pre-selected molecule into blood passing the capsule. The invention also provides a minimally invasive method for percutaneously introducing into a preselected blood vessel the device of the invention.
