Methods for treating cardiac valves with adjustable implants
First Claim
1. A method for treating a patient'"'"'s cardiac valve, said method comprising:
- providing an annuloplasty ring having a first size of a dimension of said ring in a first configuration and a second size of said dimension of said ring in a second configuration;
attaching said annuloplasty ring while in said first configuration to or near a valve annulus in a heart having a first end-diastolic volume of a ventricle; and
after said ventricle has a second end-diastolic volume, said second end-diastolic volume being less than said first end-diastolic volume, changing said annuloplasty ring from said first configuration to said second configuration, wherein said second size is less than said first size.

Abstract
Methods and devices are provided for support of a body structure. The devices can be adjusted within the body of a patient in a minimally invasive or non-invasive manner such as by applying energy percutaneously or external to the patient'"'"'s body. The energy may include, for example, acoustic energy, radio frequency energy, light energy and magnetic energy. Thus, as the body structure changes size and/or shape, the size and/or shape of the annuloplasty rings can be adjusted to provide continued reinforcement. In certain embodiments, the devices include a shape memory material that is responsive to changes in temperature and/or exposure to a magnetic field. A material having enhanced absorption characteristics with regard to a desired heating energy may be used in order to facilitate heating and adjustment of the support device.

34. A method for treating a patient'"'"'s cardiac valve, said method comprising:
-
providing an annuloplasty ring having a first size of a dimension of said ring in a first configuration and a second size of said dimension of said ring in a second configuration;
while the patient'"'"'s heart is surgically open, attaching said annuloplasty ring while in said first configuration to or near a valve annulus in a heart; and

-
providing an annuloplasty ring having a first size of a dimension of said ring in a first configuration and a second size of said dimension of said ring in a second configuration;
in said first configuration, attaching said annuloplasty ring to or near a valve annulus in a heart; and
applying acoustic energy from a focused ultrasound device to a focal zone at or near said annuloplasty ring, wherein said annuloplasty ring responds to said acoustic energy by transforming from said first configuration to said second configuration. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43)
