1. A system for treating a dilated cardiac valve, comprising:
- a delivery device including an inner catheter received in an outer catheter; and
a tension device slidably disposed within the inner catheter, the tension device including a first anchor connected to a second anchor by a tension member, the second anchor including a portion complementary to the wall of a cardiac vessel, wherein, when the tension device is delivered proximate the cardiac valve, the first anchor is inserted into a first cardiac wall and the second anchor expands within the cardiac vessel to apply tension across heart chamber via the tension member and the first anchor to reduce an annulus of the dilated cardiac valve.

23. A method of treating a dilated heart valve, the method comprising:
-
delivering a tension device comprising a first anchor connected to a second anchor by a tension member to a location within a cardiac vessel proximate the dilated heart valve;
inserting the first anchor into a heart wall proximate the dilated heart valve;
positioning the second anchor upon a cardiac vessel wall opposite the heart wall, wherein an arcuate portion of the second anchor is complementary to the cardiac vessel wall;
reducing an annulus of the dilated heart valve via the tension device. - View Dependent Claims (24, 25, 26, 27)
