Ventricular volume reduction

摘要

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.

主权项

1. A ventricular partitioning implant for insertion into a patient's ventricle, the implant comprising:
a partitioning membrane configured to span the ventricle to partition the ventricle; a support frame comprising a central hub and a plurality of support struts extending proximally from the central hub, the plurality of support struts supporting the partitioning membrane; a plurality of anchoring struts extending proximally from the central hub of the support frame and configured to anchor the partitioning member across the ventricle, wherein the plurality of anchoring struts are separate from the plurality of support struts; and a foot extending distally from the central hub; wherein the implant is configured to be inserted in a collapsed configuration and expanded into a deployed configuration within the ventricle.
