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.
Claims5
A system implantable in a mammal along the mammal's aorta, comprising:
- a plurality of inelastic members comprising biocompatible material, each member being a fully encircling ring that is set to have the same diameter throughout use in the same location once implanted,
- the members positioned around the aorta, each member having a curvature for constricting the aorta and spaced apart from one another 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.
