Implantable device and use therefor
First Claim
1. A method for percutaneously introducing into a blood vessel a device for delivering a pre-selected molecule into systemic circulation, the method comprising the steps of:
- (a) anchoring a blood permeable element to an inner wall of all intact blood vessel, the element when anchored permitting blood in the vessel to pass therethrough;
(b) introducing at a location upstream of the dement a capsule comprising viable calls which produce and secrete the pre-selected molecule; and
(c) permitting the capsule, impelled by blood flow, to be captured by the element.

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.
