System for improving cardiac function by sealing a partitioning membrane within a ventricle
First Claim
1. A device for partitioning a ventricle of a patient'"'"'s heart into a productive portion and a non-productive portion, the device comprising:
- a membrane and a membrane support frame, the membrane and the membrane support frame sized to span the patient'"'"'s ventricle, wherein the membrane and the membrane support frame are configured to have a collapsed configuration and an expanded configuration, wherein the membrane and membrane support frame are concave to form a trumpet-shaped surface in the expanded configuration;
at least one securing element on a peripheral portion of the membrane or membrane support frame configured to secure the membrane to a wall of the ventricle; and
a container secured to the device and positioned between the membrane support frame and the non-productive portion of the subject'"'"'s ventricle when the device is deployed in the subject'"'"'s ventricle.

Abstract
Partitioning devices that may be secured and sealed within a heart chamber for separating a patient'"'"'s heart chamber into a productive portion and a non-productive portion are described herein. The partitioning devices described herein may include a reinforced membrane with outwardly biased members. The reinforced membrane may have a central hub with a distally extending support stem with a plurality of feet which extend radially from a centerline axis and preferably have ends that are aligned in a common plane. These devices may be secured within the heart chamber by sealing them to the wall of the heart chamber, for example, by inflating an inflatable element on the periphery of the device. The non-productive portion may be filled with a material, including occlusive materials. Sealing and/or filling the non-productive portion formed by the devices described herein may help prevent leakage from the non-productive region.
