VENTRICULAR VOLUME REDUCTION
First Claim
1. A ventricular volume reduction implant for insertion into a patient'"'"'s ventricle to reduce the active volume of the ventricle wherein the height of the implant can be adjusted to adjust the reduction volume, the implant comprising:
- a partitioning membrane configured to span across the ventricle to partition the ventricle; and
a support frame comprising an adjustable-height stem region, the support frame comprises a plurality of support struts, wherein adjusting the height of the stem region adjusts the height of the partitioning membrane within the ventricle;
wherein the implant is configured to be inserted in a collapsed configuration and expanded into a deployed configuration within the ventricle.

Abstract
Devices and systems including implants (which may be removable) and methods of using them for reducing ventricular volume. The implants described herein are cardiac implants that may be inserted into a patient'"'"'s heart, particularly the left ventricle. The implant may support the heart wall, or may be secured to the heart wall. The implants are typically ventricular partitioning device for partitioning the ventricle into productive and non-productive regions in order to reduce the ventricular volume.
