Pericardial reinforcement device

摘要

The following relates to catheter-based devices, systems, and methods for minimally-invasively delivering an inflatable pericardial support into the pericardial space of a mammalian myocardium. The devices and systems include extending and positioning plural support members through a catheter into the pericardial space and then positioning the inflatable member on the epicardial surface of the myocardium. Once positioned, fluid can be delivered to the inflatable member to provide a confining pressure to the myocardium.

主权项

1. A cardiac treatment device comprising:
a plurality of support elements that can be positioned in a pericardial space for placement about a surface of a mammalian heart; an inflatable member that translates using the support elements from a first position within an insertion device to a deployed position within the pericardial space and surrounding the heart, the inflatable member having one or more inflatable chambers such that at least one inflatable chamber can receive a fluid under pressure; a port to insert a fluid under pressure into at least one of the one or more inflatable chambers of the inflatable member; an actuator of the insertion device that positions the inflatable member within the pericardial space; and a plurality of rods that translate relative to the support elements, the rods being coupled to a distal end of the inflatable member such that movement of the rods within the pericardial space and relative to the support elements with the actuator operates to push the inflatable member to the deployed position that surrounds the heart within the pericardial space.
