Anchored cardiovascular valve

1. An anchored cardiovascular valve, comprising:

an expandable valve support member comprising remodelable acellular extracellular matrix (ECM) from a first mammalian tissue source, said ECM valve support member being capable of transitioning from a support member pre-deployment configuration, wherein said support member is capable of being positioned within a cardiovascular structure, to a support member post-deployment configuration, wherein said support member is disposed proximate host cardiovascular tissue of said cardiovascular structure, and wherein bioremodeling of said ECM valve support member and said host cardiovascular tissue, and regeneration of new cardiovascular tissue and cardiovascular tissue structures with site-specific structural and functional properties are induced,

said ECM valve support member having a longitudinal axis, an outer surface, a lumen, an inlet portion and an outlet portion, said lumen defining a support member inner surface, said outlet portion defining an outlet in communication with said lumen, said outlet portion being outwardly reflected over and attached to said valve support member outer surface, wherein a first anchor pocket is formed therein,

said inlet portion defining an inlet in communication with said lumen, said inlet portion being inwardly reflected within said ECM valve support member lumen and attached to said support member inner surface at a first attachment point, wherein a second anchor pocket is formed therein, and wherein a first valve leaflet is formed within said ECM valve support member lumen, said valve leaflet being sized and configured to selectively restrict fluid flow through said support member; and

first and second biodegradable expandable anchoring mechanisms, said first biodegradable expandable anchoring mechanism being disposed in said first anchor pocket, said second biodegradable expandable anchoring mechanism being disposed in said second anchor pocket,

said first and second biodegradable anchoring mechanisms being capable of transitioning from an anchoring mechanism pre-deployment configuration, wherein said ECM valve support member is configured in said support member pre-deployment configuration, to an anchoring mechanism post-deployment configuration, wherein said first and second biodegradable expandable anchoring mechanisms temporarily position said ECM valve support member proximate said host cardiovascular tissue of said cardiovascular structure and maintain contact therewith for an anchor support period of time within said process of new cardiovascular tissue regeneration, wherein bioremodeling of said ECM valve support member and host cardiovascular tissue, and regeneration of cardiovascular tissue structures with site-specific structural and functional properties are induced, and wherein said first and second biodegradable expandable anchoring mechanisms degrade during said anchor support period of time.

2. The anchored valve of claim 1 , wherein said support member inlet portion is attached to said support member inner surface at two attachment points, and wherein first and second valve leaflets are formed within said ECM valve support member lumen.

3. The anchored valve of claim 1 , wherein said support member inlet portion is attached to said support member inner surface at three attachment points, and wherein first, second and third valve leaflets are formed within said ECM valve support member lumen.

4. The anchored valve of claim 3 , wherein said three attachment points are positioned substantially within a common plane, said common plane being substantially perpendicular to said longitudinal axis of said ECM valve support member.

5. The anchored valve of claim 1 , wherein said first tissue source is selected from the group consisting of small intestine submucosa (SIS), urinary bladder submucosa (UBS), stomach submucosa (SS), mesothelial tissue, placental extracellular matrix, ornomentum extracellular matrix, cardiac extracellular matrix, kidney extracellular matrix, pancreas extracellular matrix, and combinations thereof.

6. The anchored valve of claim 1 , wherein said remodelable ECM comprises an additional pharmacological agent.

7. The anchored valve of claim 6 , wherein said pharmacological agent comprises a statin selected from the group consisting of atorvastatin, cerivastatin, fluvastatin, lovastatin, mevastatin, pitavastatin, pravastatin, rosuvastatin and simvastatin.

8. The anchored valve of claim 6 , wherein said pharmacological agent comprises a growth factor selected from the group consisting of transforming growth factor alpha (TGF-alpha), transforming growth factor beta (TGF-beta), fibroblast growth factor-2 (FGF-2), basic fibroblast growth factor (bFGF) and vascular epithelial growth factor (VEGF).

9. The anchored valve of claim 6 , wherein said pharmacological agent comprises an anti-arrhythmic agent selected from the group consisting of quinidine, procainamide, disopyramide, lidocaine, phenytoin, mexiletine, flecainide, propafenone, moricizine, propranolol, esmolol, timolol, metoprolol, atenolol, amiodarone, sotalol, ibutilide, dofetilide, verapamil, diltiazem, adenosine and digoxin.

10. The anchored valve of claim 1 , wherein said first and second biodegradable expandable anchoring mechanisms comprise a biodegradable polymeric material selected from the group consisting of a copolymer of polylactic acid and copolyesters of e-caprolactone.

11. The anchored valve of claim 1 , wherein said first and second biodegradable expandable anchoring mechanisms comprise magnesium.

12. The anchored valve of claim 1 , wherein said first and second biodegradable expandable anchoring mechanisms comprise crosslinked ECM from a second mammalian tissue source selected from the group consisting of SIS, UBS, SS, mesothelial tissue, ornomentum extracellular matrix, cardiac extracellular matrix, kidney extracellular matrix, pancreas extracellular matrix, lung extracellular matrix, and combinations thereof.
