1. A method for modifying a vascular valve in a patient, comprising:
- accessing a vascular valve in the body of a patient; and
attaching a remodelable material to at least a first valve leaflet and a second valve leaflet in the vascular valve, the remodelable material effective upon implantation to become replaced by native patient tissue so as to provide a remodeled tissue spanning between the first valve leaflet and the second valve leaflet to fuse the first valve leaflet to the second valve leaflet.

Abstract
Described are methods and systems for modifying vascular valves in order to reduce retrograde blood flow through the valves. Preferred methods include connecting vascular valve leaflets with at least one remodelable material, such that the valve leaflets become fused by the ingrowth of the patient'"'"'s native tissue. Preferred remodelable materials include collagenous extracellular matrix material, such as small intestine submucosa.

9. A method for modifying the flow of blood in a vascular vessel, comprising:
-
accessing a vascular valve in the body of a patient; and connecting a first valve leaflet in the vascular valve to a second valve leaflet in the vascular valve with a material that is receptive to tissue ingrowth so as to promote native patient tissue to grow into the material to fuse the first valve leaflet to the second valve leaflet. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method for modifying a vascular valve in a patient, comprising:
-
accessing a vascular valve in the body of a patient; and locating an extracellular matrix material in the vascular valve such that the extracellular matrix material contacts a first valve leaflet and extends therefrom to contact a second valve leaflet so as to promote native patient tissue to grow into the extracellular matrix material to fuse the first valve leaflet to the second valve leaflet. - View Dependent Claims (19, 23, 24, 25)

20. A method for modifying a vascular valve in a patient, comprising:
locating an extracellular matrix material in a vascular valve such that the extracellular matrix material contacts a first valve leaflet and extends therefrom to contact a second valve leaflet so as to promote native patient tissue to grow into the extracellular matrix material to fuse the first valve leaflet to the second valve leaflet, wherein said extracellular matrix material is delivered to said vascular valve with a delivery catheter. - View Dependent Claims (21, 22)
