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.

The present invention relates to an implantable device for improving the pump function of the heart of a human patient by applying an external force on the heart muscle, said device comprising at least one pump device comprising: a first part having a first surface, and a second part having a second surface. The first part is displaceable in relation to the second part and said first and second surfaces abut each other, at least partially. The second part exerts, directly or indirectly, force on an external part of said heart muscle.

Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning, including: (a) a jacket made of a flexible biocompatible material, the jacket having an open top end that is received around the heart and a bottom portion that is received around the apex of the heart; and (b) at least one inflatable bladder disposed on an interior surface of the jacket, the inflatable bladder having an inelastic outer surface positioned adjacent to the jacket and an elastic inner surface such that inflation of the bladder causes the bladder to deform substantially inwardly to exert localized pressure against a region of the heart.

An elongated actuator including: an elongated inner tube for carrying a pressurized actuation fluid; a helical coil wrapped around the elongated inner tube; wherein the actuator undergoes actuation by means of pressure fluctuations in the elongated inner tube.

A surgical or laparoscopic method of creating and maintaining an opening in the thoracic diaphragm of a patient. The method comprising the steps of creating an incision in the thoracic diaphragm and thereby creating an opening in the thoracic diaphragm, placing a diaphragm passing part in said opening created in the thoracic diaphragm, passing from the abdomen through the thoracic diaphragm and into the thorax; wherein the step of placing said diaphragm passing part comprises placing a force transferring part of the diaphragm passing part in contact with the thoracic diaphragm, the force transferring part being adapted to transfer force between the abdominal side of the thoracic diaphragm and the thoracic side of the thoracic diaphragm while sliding against the thoracic diaphragm.

An implantable heart help device adapted for implantation in a human patient is provided. The device comprising a fixating member adapted to fixate said device to a part of the human body comprising bone. Further 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.

The embodiments relate to cardiac assist devices that comprise a jacket that wraps the exterior of the heart, where the jacket comprises a left chamber and a right chamber overlaying the left and right ventricles of the heart, respectively, where the chambers are expanded pneumatically to exert pressure on the heart and thereby mechanically assist its pumping. The timing of expansion of the left and right bladders is controlled by an electrical controller to match the desired or natural timing of contraction of the left and right ventricles, where both the left and right chambers may not expand simultaneously but are timed to optimize assistance of the heart. The embodiments provide jackets that apply pneumatic pressure to the right and left ventricles separately in timing to provide mechanical cardiac resynchronization therapy, as distinct from the conventional electrical stimulation cardiac resynchronization therapy.
