PAPILLARY MUSCLE POSITION CONTROL DEVICES, SYSTEMS, & METHODS
First Claim
1. A papillary muscle positioning device comprising:
- a first anchor configured to fixedly connect to an in situ valve of a heart ventricle;
a second anchor configured to fixedly connect to a muscle wall of the valve; and
a support structure with an adjustable length, a selected length being releasably lockable, the support structure 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.

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.
