Abstract
Official abstract text for this publication.
An osmotic delivery system flow modulator includes an outer shell constructed and arranged for positioning in an opening, an inner core inserted in the outer shell, and a fluid channel having a spiral shape defined between the outer shell and the inner core. The fluid channel is adapted for delivery of an active agent formulation from the reservoir of the osmotic delivery system.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of making an implantable, osmotic delivery system for an active agent formulation, comprising: positioning a piston within a reservoir, the piston defining within the reservoir a first chamber and a second chamber, wherein the reservoir is made of an impermeable, metallic material; positioning an osmotic engine within the first chamber; positioning a semipermeable plug in a first opening at a first end of the reservoir, adjacent the osmotic engi…
