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.

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.

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.

An operable implant adapted to be implanted in the body of a patient, the operable implant comprising an operation device and a body engaging portion, wherein the operation device comprises a first unit comprising a receiving unit for receiving wireless energy and a first gear system adapted to receive mechanical work having a first force and first velocity, and output mechanical work having a different second force and a different second velocity. The operation device further comprises a second unit comprising an electrical motor adapted to transform electrical energy to the mechanical work, and a distance element adapted to separate the first and second units such that the receiving unit, when receiving wireless energy, is not substantially affected by the second unit.

A method of fixating an implantable heart help device in a human patient is provided. The method comprises the steps of: cutting the skin of said human patient, dissecting an area of the body comprising bone, and fixating said implantable heart help device to said part of the body comprising bone.

Heart failure (HF) is a global pandemic affecting at least 26 million people worldwide. Thus, methods and devices that reduce the clinical and economic burden of HF are critical. The present invention features an adjustable cardiac sleeve comprising a basal ring structure and an apical hub couple together, wherein the basal ring structure comprises a plurality of interconnected loops made from a distensible wire.

Devices, systems, and methods for combinatorial treatment of a condition with an implantable damping device and therapeutic agent (e.g., drug) are disclosed herein. Methods for treating one or more effects of the condition, such as a neurological condition, include providing the implantable damping device and at least neck one other therapy, such as a therapeutic agent, that treats the condition to the patient. The implantable damping device includes a flexible damping member and an abating substance and can be placed in apposition with a blood vessel. The flexible damping member forms a generally tubular structure having an inner and an outer surface, the inner surface formed of a sidewall having a partially deformable portion. The abating substance is disposed within the partially deformable portion and moves longitudinally and/or radially within the partially deformable portion in response to pulsatile blood flow.

A spring (3, 3′) comprising a plurality of elements (30), each element (3) comprising a rigid portion (31) and a flexible beam (32), the extremities (320, 321) of the flexible beam being supported by the rigid portion (31), the flexible beam (32) having a single stable position, so that the flexible beam can be deformed when a pressure is exerted between said extremities in the direction of the rigid portion (31), and returns to said single stable position when the pressure is released, and wherein the rigid portion (31) of at least one element (30) is in contact with the flexible beam (32) of the next element between said extremities (320, 321) of the flexible beam (32), so that the spring has a negative stiffness over an operating range. The arrangement ensures a pure radial compression/expansion of the spring.
