Anchorage devices comprising an active pharmaceutical ingredient
First Claim
1. An anchorage device comprising a mesh substrate coupled to an implantable medical device, said mesh substrate comprising two sheets that define a pocket, said implantable medical device being positioned in said pocket, said mesh substrate having a coating comprising a polymer and at least one active pharmaceutical ingredient;
- wherein said mesh substrate comprises pores ranging in size between about 5 mm to about 10 mm,wherein said mesh substrate comprises one or more apertures,wherein said apertures are larger than said pores,wherein one of said sheets is formed with a non-biodegradable material and one of said sheets is formed with a biodegradable material, andwherein said sheet that is formed with said non-biodegradable material has no pores.

Abstract
An anchorage device comprising a mesh substrate coupled to an implantable medical device is disclosed, where the mesh substrate has a coating comprising a polymer, and the mesh further comprises at least one active pharmaceutical ingredient. The active pharmaceutical agent is designed to elute from the mesh over time. The mesh substrate can be configured to reduce the mass of the anchorage device such that tissue in-growth and/or scar tissue formation at the treatment site is reduced. In some embodiments, the mesh substrate can be formed with a mesh having a low areal density. In some embodiments, the mesh substrate can include one or more apertures or pores to reduce the mass of the substrate.
