Implantable device and uses therefor
First Claim
1. An implantable device for delivering a pre-selectd molecule into systemic circulation, the device comprising in combination:
- (a) a blood permeable element comprising at least one metallic filament anchorable to an inner wall of a blood vessel which when anchored to the inner wall of the vessel permits blood in the vessel to pass therethrough; and
(b) a capsule having disposed therein viable cells which produce and secrete the pre-selected molecule, wherein the capsule, when introduced into the vessel, is retained within the vessel by the blood permeable element and the cells disposed therein produce and secrete the pre-selected molecule into blood passing the capsule.

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 preselected 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.
