Systems and methods for cardiac remodeling
View Patent ↗Described herein are devices and methods for improving the hemodynamic function of a patient. In particular, a first device adapted to reshape an atrio-ventricular valve is used in combination with a second device configured to further alter the blood flow through the valve. The first device is typically an implant positioned in the subvalvular space of a ventricle. The second device may be an annuloplasty implant, a non-annulus valve apparatus implant, a ventriculoplasty implant, or a cardiac rhythm management device.
1. A method for reshaping a heart, comprising:
positioning a first therapy implant adjacent a first cardiac tissue using a first delivery tool, wherein the first cardiac tissue is non-leaflet tissue at a subvalvular space of a ventricle and the first therapy implant comprises a first plurality of tissue anchors slidably coupled to a first tether;
reconfiguring the first cardiac tissue using the first therapy implant;
reconfiguring a second cardiac tissue at a different non-annulus location from the first cardiac tissue using a second therapy implant separate from the first therapy implant that is delivered by a second delivery tool; and
withdrawing the first and second delivery tools and leaving the first and second therapy implants within the heart.
2. The method of claim 1 , wherein reconfiguring the first cardiac tissue occurs before reconfiguring the second cardiac tissue.
3. The method of claim 1 ,
wherein the second cardiac tissue is inferior to a third order chordae tendineae.
4. The method of claim 1 , wherein the second cardiac tissue is superior to a papillary muscle.
5. The method of claim 1 , wherein the second cardiac tissue is inferior to a papillary muscle.
6. The method of claim 1 , wherein the second therapy implant is oriented generally perpendicular to a longitudinal axis of the ventricle.
7. The method of claim 1 , further comprising passing a guide catheter in a retrograde direction through an aorta.
8. The method of claim 7 , wherein positioning the first therapy implant adjacent the first cardiac tissue comprises passing a first delivery catheter through the guide catheter and toward the first cardiac tissue.
9. The method of claim 8 , further comprising withdrawing the first delivery catheter from the guide catheter after reconfiguring the first cardiac tissue using the first therapy implant.
10. The method of claim 7 , wherein reconfiguring the second cardiac tissue comprises passing a second delivery catheter through the guide catheter and toward the second cardiac tissue.
11. The method of claim 1 , wherein reconfiguring the first cardiac tissue using the first therapy device comprises manipulating a cinching member of the first therapy implant.
12. The method of claim 11 , wherein the first therapy implant is wholly contained in one heart chamber.
13. The method of claim 1 , wherein the second therapy implant comprises a means for reducing a ventricular dimension.
14. The method of claim 13 , wherein the ventricular dimension is a septolateral dimension.
15. The method of claim 1 , further comprising implanting a third therapy implant at a location different from the locations of the first and second therapy implants.
16. The method of claim 1 , wherein the first and second delivery tools are the same tool.
