Ventricular volume reduction
First Claim
1. A ventricular volume reduction implant for insertion into a ventricle to reduce an active volume of the ventricle, the implant having a collapsed configuration that may be passed through a cannula and an expanded configuration spanning a portion of the ventricle, the implant comprising:
- a plurality of flattened leaves extending outwards from a central hub, wherein in the expanded configuration the leaves are configured to form a partitioning barrier across the ventricle, wherein the leaves are discrete from each other; and
a plurality of anchors at the distal edge of the partitioning barrier configured to secure the partitioning barrier to the walls of 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.

12. An implant having a collapsed configuration and an expanded configuration, the implant comprising:
-
a central hub; and a plurality of flattened plates extending from the central hub, wherein the plates are discrete from each other, wherein the plates are overlapping in the collapsed configuration and fanned out in the expanded configuration, wherein in the collapsed configuration the implant is configured to be delivered percutaneously through a delivery catheter and in in the expanded configuration the implant is configured to partition a chamber in a heart. - View Dependent Claims (13, 14, 15, 16, 17, 18)
