Adjustable cardiac valve implant with selective dimensional adjustment
First Claim
1. An annuloplasty device, configured to support a heart valve having an annulus that defines a perimeter around the valve, said annuloplasty device comprising:
- a body, comprising;
an anterior portion;
a posterior portion;
two lateral portions corresponding to intersections of said anterior portion and said posterior portion;
wherein said annuloplasty device has a first shape in a first configuration and a second shape in a second configuration;
wherein said annuloplasty device is configured to transform from said first configuration to said second configuration in response to a first activation energy applied thereto; and
wherein said transformation is configured to reduce a distance between said anterior portion and said posterior portion without substantially decreasing a distance between said two lateral portions; and
a flexible member coupled to the body;
wherein the flexible member is configured such that, when the annuloplasty device is secured to the heart, the flexible member is anchorable to heart tissue at or adjacent to the annulus, along at least a portion of the perimeter, the portion of the perimeter extending between fibrous trigones of the heart.

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. 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 an anterior portion, a posterior portion and two lateral portions corresponding to intersections of the anterior portion and the posterior portion. The devices have a first shape in a first configuration and a second shape in a second configuration and are configured to transform from the first configuration to the second configuration in response to an activation energy applied thereto. The transformation is configured to reduce a distance between the anterior portion and the posterior portion without substantially decreasing a distance between the two lateral portions.

33. An annuloplasty device configured to be secured to a heart, at or near a base of a heart valve having an annulus that defines a perimeter around the valve, the annuloplasty device comprising:
-
a body, comprising; an elongate members comprising; an anterior portion; a posterior portion; and two lateral portions corresponding to intersections of said anterior portion and said posterior portion; and a first shape memory member at least partially covering or contacting said elongate member; wherein said first shape memory member is configured to respond to a first activation energy applied thereto by reducing a distance between said anterior portion and said posterior portion without substantially reducing a distance between said two lateral portions; and a flexible member coupled to the body; wherein the flexible member is configured to be anchored to a heart tissue, at or adjacent to the annulus along at least a portion of the perimeter, the portion of the perimeter extending between fibrous trigones of the heart; and wherein, when the device is secured to the heart, and when the flexible member is anchored to the heart tissue, and the first shape memory member responds to the first activation energy, a distance between an anterior aspect and posterior aspect of the valve is reduced. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. An annuloplasty device comprising:
-
adjustment means for changing a patient'"'"'s cardiac valve annulus size in an anteroposterior dimension without substantially changing said annulus in a lateral dimension; and wherein the changing occurs in response to a transmission of energy from a non-invasive source external to the patient'"'"'s heart to said adjustment means; and anchoring means coupled to said adjustment means, said anchoring means configured to anchor the device to heart tissue (1) at or adjacent to the annulus, and (2) along at least a portion of a perimeter around the valve defined by the annulus, the at least a portion of the perimeter extending between fibrous trigones of the heart.

48. An annuloplasty device that changes a patient'"'"'s cardiac valve annulus size in an anteroposterior dimension without substantially changing said annulus in a lateral dimension, wherein the changing occurs in response to a transmission of energy from a non-invasive source external to the patient'"'"'s heart to said annuloplasty device, comprising:
-
an arcuate body; a flexible member, coupled to the arcuate body; wherein the flexible member is configured to anchor the device to heart tissue (1) at or adjacent to the annulus, and (2) along at least a portion of a perimeter around the valve defined by the annulus, the at least a portion of the perimeter extending between fibrous trigones of the heart; wherein, when the device is secured to the heart, and when the flexible member is anchored to the heart tissue, and when the device responds to the energy transmission, the cardiac valve annulus size changes in the anteroposterior dimension.

49. An annuloplasty device, configured to support a heart valve having an annulus that defines a closed perimeter, the device comprising:
-
an arcuate body that has a first shape in a first configuration and a second shape in a second configuration; wherein the arcuate body is configured to transform from the first configuration to the second configuration in response to an activation energy applied thereto; wherein the transformation reduces a distance between an anterior portion of the arcuate body and a posterior portion of the arcuate body without substantially decreasing a distance between two lateral portions of the arcuate body; and a flexible member coupled to the arcuate body; wherein the flexible member is configured to be anchored to heart tissue at or adjacent to the annulus, along at least a portion of the perimeter, the portion of the perimeter extending between fibrous trigones of the heart; and wherein, when the device is secured to the heart, and when the flexible member is anchored to the heart tissue, and when the device responds to the activation energy, the cardiac valve annulus size changes in the anteroposterior dimension.
