Abstract
The present invention provides methods and modalities that can modify wave reflection in the vascular system in order to create constructive interactions between existing wave dynamics and new reflective waves for the purpose of lowering the workload on the heart and increasing cardiac output, providing a viable option for the prevention and treatment of many heart conditions and diseases.
Claims20
A method of reducing a hemodynamic load on a mammal's heart, the method comprising:
- positioning a plurality of rings around an aorta of the mammal, the rings each encircling a portion of the aorta and spaced apart from one another along the aorta;
- constricting the aorta with a curvature of each of the rings without changing ring diameter after implantation to generate a plurality of artificial pressure wave reflection sites in the aorta to reduce a hemodynamic load on the mammal's heart as compared to a hemodynamic load without the artificial pressure wave reflection sites.
A method of reducing a hemodynamic load on a mammal's heart, the method comprising affecting a reflective wave in a blood vessel of the mammal.
