Prosthetic device for heart valve reinforcement and remodeling procedures
View Patent ↗A prosthetic heart valve reinforcement ring is disclosed. The prosthetic includes an outer ring sized and dimensioned to fit around an annulus of a heart valve and an inner ring configured and arranged to couple to the outer ring. The inner ring and the outer ring have complimentary mating formations configured and arranged to grip sutures therebetween. A method of reinforcing heart valve is also disclosed. Sutures are provided around an annulus of a heart valve. The sutures are corralled within an outer sizing ring. The outer sizing ring is placed around the annulus of the heart valve. An inner sizing ring is inserted within the outer ring, locking the sutures. The sutures are adjusted and the heart valve is tested for a proper fit. The outer sizing ring is removed and a prosthetic ring is placed over the inner sizing ring, locking the sutures. The sutures are tied.
1. A method of reinforcing a heart valve, comprising:
providing annular sutures sutured to an annulus of the heart valve;
corralling the annular sutures within an outer sizing ring;
after the annular sutures have been corralled, placing the outer sizing ring around the annulus of the heart valve;
inserting an inner sizing ring within the outer sizing ring, temporarily locking the annular sutures radially between the outer sizing ring and the inner sizing ring;
during insertion of the inner sizing ring within the outer sizing ring contemporaneously adjusting the annular sutures to achieve a corrected fit of leaflets of the heart valve;
testing the corrected fit of the leaflets after the annular sutures have been adjusted;
after the corrected fit of the leaflets has been determined, replacing the outer sizing ring with a prosthetic ring over the inner sizing ring-thereby locking the annular sutures between the prosthetic ring and the inner sizing ring; and
tying the annular sutures.
2. The method of claim 1 , further comprising removing the inner sizing ring.
3. The method of claim 2 , wherein the inner sizing ring is removed after the annular sutures are tied.
4. The method of claim 1 , further comprising tying the annular sutures to the prosthetic ring.
5. The method of claim 1 , further comprising tying the annular sutures to both the inner sizing ring and the prosthetic ring.
6. The method of claim 1 , further comprising using a knot-tying device to tie the annular sutures in the tying the annular sutures step.
7. The method of claim 1 , further comprising wrapping the annular sutures around the prosthetic ring.
8. The method of claim 1 , further comprising suturing the annular sutures through graft material extending from the prosthetic ring.
9. The method of claim 1 , further comprising suspending tabs of tissue where leaflets meet to peaks formed in the prosthetic ring.
10. The method of claim 1 , further comprising repeating the steps of adjusting the annular sutures and testing the heart valve until the corrected fit of the leaflets is achieved.
11. The method of claim 1 , further comprising testing the heart valve for the corrected fit of the leaflets after the outer sizing ring is replaced with the prosthetic ring.
