System for improving cardiac function by sealing a partitioning membrane within a ventricle
First Claim
1. A ventricular partitioning device comprising:
- a membrane disposed around a center region;
a valve positioned in the center region; and
an inflation channel radially extending from the valve to a peripheral region of the membrane, wherein the inflation channel is in fluid communication with the valve,wherein the valve is configured to control passage of a fluid into the inflation channel,wherein the membrane is outwardly expandable when the fluid passes into the inflation channel, andwherein the device further comprises an inflatable element positioned on or in the peripheral region of the membrane, wherein the inflatable element is in fluid communication with the inflation channel and the valve.

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 membrane with a plurality of inflatable elements. The membrane may include a valve disposed in a central region of the membrane with a plurality of inflation channels extending radially from the valve. These devices may be secured within the heart chamber by sealing them to the wall of the heart chamber, for example, by inflating the plurality of inflatable elements 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.
