Papillary muscle position control devices, systems, and methods
First Claim
1. A papillary muscle positioning system comprising:
- a first anchor configured to fixedly connect to an in situ heart valve situated in a heart between a heart ventricle and atrium;
a second anchor configured to fixedly connect to at least one of a ventricular wall and a papillary muscle of the heart;
a support structure coupled between and to the first anchor and the second anchor such that adjusting a length of the support structure varies a distance between the first anchor and the second anchor;
an adjustment mechanism at the first anchor configured to lockably adjust the length of the support structure; and
an adjustment device for adjusting, from outside the heart and while the heart is beating, the adjustment mechanism to adjust the length of the support structure and a distance between an annulus of the heart valve and a papillary muscle of the heart.

Abstract
Papillary muscle position control devices (900) systems and methods are provided. According to an exemplary embodiment, a papillary muscle position control device generally comprises a first anchor (905), a second anchor (920), and a support structure (915). The first anchor can be configured to fixedly connect to an in situ valve of a heart ventricle. The second anchor can be configured to fixedly connect to a muscle wall of the valve. The support structure can be configured to have an adjustable length and be coupled to the first anchor and second anchor such that adjusting the length of the support structure varies a distance between the first anchor and the second anchor. Other embodiments are also claimed and described.
