1. A method for modifying a vascular valve in a patient, comprising:
- connecting at least two valve leaflets in a vascular valve in at least one location with an extracellular matrix material, so as to promote tissue of the patient to remodel and connect said leaflets, wherein said extracellular matrix material is in the form of a suture.

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.
