APPARATUS, SYSTEMS, AND METHODS FOR PERCUTANEOUS PNEUMATIC CARDIAC ASSISTANCE

A cardiac assist system includes a pneumatic effector which is implanted beneath a pericardial sac and over a myocardial surface overlying the patient's left ventricle. A port is implanted and receives a percutaneously introduced cannula. The port is connected to supply a driving gas received from the cannula to the pneumatic effector. An external drive unit includes a pump assembly and control circuitry which operate the pump to actuate the pneumatic effector in response to the patient's sensed heart rhythm. A connecting tube has a pump end connected to the pump and a percutaneous port-connecting end attached to the implantable port.

Cardiac Compression Device Having Passive and Active Chambers

The present invention provides a direct cardiac compression device for individualized support at different locations around the heart, the device comprising: a housing shaped to conform to the shape of the heart and to surround the heart; two or more active chambers positioned adjacent to the housing, wherein the two or more active comprise one or more right active chambers positioned on the right ventricle side of the heart and one or more left active chambers positioned on the left ventricle side of the heart, wherein the two or more active chambers are designed to conform to the shape of the heart, each active chamber comprising an inner membrane sealingly attached along its periphery to the housing and an active fluid individually supplied thereto; a right input connection in fluid communication with the one or more right active chambers to ingress the active fluid into each of the one or more right active chambers; a left input connection in fluid communication with the one or more left active chambers to ingress the active fluid into each of the one or more left active chambers, and a driver in fluid communication with each of the right input connection and the left input connection to individually and periodically ingress and egress the active fluid therefrom, wherein the active fluid individually inflates the one or more right active chambers and the one or more left active chambers to compress the heart.

Total Heart Assistance Device

The present invention relates generally to the field of cardiac, vascular system, and heart assistance devices. It provides the energy required to keep the blood flowing in the pulmonary and systemic circuits to a desired level, acting on one or more chambers. Actual problems of Total Artificial Heart pumping blood are design limitations, infection, hemorrhage, end organ failure, thromboembolism, device disfunction, life span of diaphragms, and impossibility to restore the heart but with a transplant. The device is external and has four units replicating the natural heart and its dynamics, driving by a pneumatic transcutaneous system to provide the energy needed up to the desired working level of a healthy organ. Applications are on those types of surgical or clinical treatment of patients with Diastolic Heart Failure or used to treat Heart Failure with Reduced Ejection Fraction (Systolic Heart Failure), the device can be left connected permanently of for healing.

The present invention relates to surgical or laparoscopic method of creating and maintaining an opening in the thoracic diaphragm of a patient. In said method, an incision in the thoracic diaphragm is created, thereby creating an opening in the thoracic diaphragm. Further a diaphragm passing part is placed in said opening created in the thoracic diaphragm, passing from the abdomen, through the thoracic diaphragm at the pericardial contacting section, into the pericardium; When placing the diaphragm passing part a force transferring part of the diaphragm passing part is placed in contact with the thoracic diaphragm, the force transferring part being adapted to, by motion of the force transferring part, transfer force between the abdominal side of the thoracic diaphragm and the thoracic side of the thoracic diaphragm or the pericardium while sliding against the thoracic diaphragm.

Synchronizing a pulsatile cardiac assist device with a pacemaker

Methods for synchronizing the actions of a pulsatile cardiac assist device with a dysfunctional heart using a cardiac pacemaker. Aspects include receiving a signal from the pacemaker and actuating the pulsatile cardiac assist device in response to the signal from the pacemaker to either help push blood out of the heart during systole or to help suck blood from the atria during diastole.

Left atrial appendage stasis reduction

Methods and devices that prevent stasis in the LAA by either increasing the flow through the LAA or by closing off or sealing the LAA. Increasing the flow is accomplished through shunts, flow diverters, agitators, or by increasing the size of the ostium. Closing off the LAA is accomplished using seals or by cinching the LAA.

OPERABLE IMPLANT
