Method of heart valve repair
View Patent ↗Catheter based systems and methods for securing tissue including the annulus of a mitral valve. The systems and methods employ catheter based techniques and devices to plicate tissue and perform an annuloplasty.
1. A method of modifying the spatial relationship between a coronary sinus and an annulus of a mitral valve, the coronary sinus lying at least partially apart from the annulus at least at one location, comprising:
applying a fastener through the annulus and into the coronary sinus;
temporarily anchoring the coronary sinus to the annulus at least at the one location while applying the fastener; and
using at least the applied fastener to bring the coronary sinus closer to the annulus at least at the one location.
2. The method of claim 1 , wherein using at least the applied fastener to bring the coronary sinus closer to the annulus further comprises: moving the coronary sinus downwardly to a position adjacent the annulus at least at the one location.
3. The method of claim 1 , wherein temporarily anchoring the coronary sinus to the annulus further comprises moving the coronary sinus and annulus together with magnetic elements at least at the one location.
4. The method of claim 1 , further comprising: modifying the annulus so as to reduce regurgitation of blood through the mitral valve.
5. The method of claim 4 , wherein modifying the annulus further comprises:
plicating the annulus with fasteners.
6. The method of claim 4 , wherein modifying the annulus further comprises: moving the posterior and anterior sides of the annulus closer together, and fixing the annulus such that the posterior and anterior sides remain closer together.
7. The method of claim 4 , wherein modifying the annulus further comprises: placing anchors in the coronary sinus, and cinching the anchors together.
8. A method of modifying the annulus of a mitral valve, wherein a coronary sinus is positioned proximate to the annulus at least at one location, the method comprising:
applying a fastener through the annulus and into the coronary sinus;
temporarily anchoring the coronary sinus to the annulus at least at the one location while applying the fastener; and
modifying the annulus so as to reduce regurgitation of blood through the mitral valve using at least the applied fastener.
9. The method of claim 8 , wherein temporarily anchoring the coronary sinus to the annulus further comprises moving the coronary sinus and annulus together with magnetic elements at least at the one location.
10. The method of claim 8 , wherein modifying the annulus further comprises: plicating the annulus with fasteners.
11. The method of claim 8 , wherein modifying the annulus further comprises: moving the posterior and anterior sides of the annulus closer together, and fixing the annulus such that the posterior and anterior sides remain closer together.
12. The method of claim 8 , wherein modifying the annulus further comprises: placing anchors in the coronary sinus, and cinching the anchors together.
