Abstract

An implantable device system includes an implantable device, such as an annuloplasty ring, for controlling at least a shape and/or size of a heart valve annulus. The implantable device includes an arcuate body and an adjustment system configured to adjust the shape and/or size of the arcuate body. An adjustment tool is configured to be coupled to the adjustment system so that the adjustment tool can be used to activate and control adjustment of the arcuate body. A sensor system is configured to be coupled to the implantable device. The sensor system includes a first sensor configured to measure physiological data at an inflow portion of the valve annulus when the implantable device is implanted into the valve annulus, and a second sensor configured to measure physiological data at an outflow portion of the valve annulus when the implantable device is implanted into the valve annulus.

Claims

wherein the first sensor includes a first coupling element extending therefrom and the second sensor includes a second coupling element extending therefrom, at least one of the first and second coupling elements being configured to attach to the implantable device,

wherein a wire ring is coupled to the arcuate body and configured to attach to at least one of the first and second coupling elements.

2. The implantable device system of claim 1, wherein the implantable device includes an adjustment system configured to adjust at least one of a shape and a size of the arcuate body, and the adjustment system includes an adjustment tool configured to be coupled to the adjustment system so that the adjustment tool can be used to activate and control adjustment of the arcuate body.

3. The implantable device system of claim 2, wherein the arcuate body includes a first body portion configured to slide with respect to a second body portion upon adjustment of the arcuate body.

4. The implantable device system of claim 3, wherein the first body portion is positioned at least partially within the second body portion.

5. The implantable device system of claim 4, wherein the second body portion is more rigid than the first body portion.
