Embodiment Construction

[0033] 1. CRCS design goals and implementation

[0034] Major issues related to CRCS implementation include fixation and synchronized sac actuation in response to systole and relaxation. To stimulate electrophysiological reverse remodeling, suction assistance should be applied over the ventricular free wall region. The CRCS design of the present invention intends to deliver biventricular epicardial compressions synchronized with the heart rhythm, with atrioventricular conduction delay control and simultaneous left and right cardiac assistance being the design goals to be achieved. The fixation method and cardiac resynchronization pump design are described below.

[0035] soft fixed

[0036] Hard fixation methods such as vacuum aspiration, glue adhesion, and fixed sutures are currently excluded. Instead, consider a soft fixation strategy that allows a non-interfering capsule to fit snugly around the heart. Soft fixation means fixation that confines or wraps the device aroun...

Abstract

The present direct cardiac compression (DCC) design, termed Cardiac Resynchronization Compression Sac System (CRCSS), combines together the mechanical and electrical characteristics associated with DCC and cardiac resynchronization therapy (CRT), respectively. The CRCSS comprises a shell at least one opening on the shell, and at least one inflatable balloon, and a pumping system. The shell is custom manufactured to substantially conform to the contour of a portion of a heart, die contour of the heart being obtained by an imaging system. The opening on the shell is designed for passing pericardial fluid so as not to impede the myocardial contraction. The inflatable balloon attaches to at least one predetermined location of the inner surface of the shell. Furthermore, the shell naturally positions in the pericardium space without resorting to any artificial force to prevent it from dislodging from the heart, and when the inflatable balloon inflates at least one ventricular free wall of the heart is compressed.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 010,241, filed January 4, 2008. technical field [0003] The present invention relates to a cardiac compression system, and more particularly, to a cardiac resynchronization compression balloon system. Background technique [0004] I. Direct cardiac compressions [0005] The concept of direct cardiac compressions (DCC) as a modality of circulatory support came from emergency resuscitation of the heart and lungs. Compared with other existing ventricular assist devices (Ventricular Assist Device, VAD), the most unique advantage of DCC is that it does not touch the blood. By directly applying force to compress the decompressed heart, the extrinsic DCC device helps to increase the systolic state of the ventricles and thereby increase cardiac output. DCC can be implemented by (but not limited to) the following methods: [0006] skeletal muscle pum...
