A surgical method of treating a patient is disclosed. The method comprises the steps of: cutting the patient's skin and abdominal wall; dissecting an area of the patient's intestine; and dissecting a portion of the dissected intestinal area such that intestinal mesentery connected thereto is opened in such a way that supply of blood through the mesentery to the dissected intestinal area is maintained as much as possible on both sides of the dissected portion. The method further comprises the steps of dividing the patient's intestine in the dissected portion so as to create an upstream part of the intestine with a first intestinal opening and a downstream part of the intestine with a second intestinal opening with the mesentery still maintaining a tissue connection between the upstream and downstream intestine parts.

An implantable device for improving the pump function of the heart of a human patient by applying an external force on a first position of the heart muscle following the heart's contractions. The implantable device comprising a first pump device adapted to assist the pump function of the heart. The pump device comprises a first reservoir having a first volume and adapted to varying said first volume, a second reservoir having a second volume and adapted to varying said second volume, a fluid connection adapted to fluidly connect said first reservoir with said second reservoir, such that fluid can flow between said first reservoir and said second reservoir. The reservoir, said second reservoir and said fluid connection form a fully implantable pump device adapted to maintain a fluid in a closed system, when in operation and wherein said fully implantable pump device is adapted to transfer force by transferring fluid from said first reservoir to said second reservoir to directly or indirectly apply an external force on the first position of the heart muscle, following the heart's contractions, for improving the pump function of the heart, when said device is implanted. The implantable device further comprises a sensor sensing muscle contractions of the heart.

A medical device for assisting a function of the heart is provided. The heart is placed in the thorax, the thoracic diaphragm is dividing the thorax from the abdomen and the pericardium is surrounding the heart and is attached to the thoracic diaphragm at a pericardial contacting section of the thoracic diaphragm. The medical device comprises a diaphragm passing part adapted to pass from the abdomen, through the thoracic diaphragm at the pericardial contacting section, into the pericardium, wherein said diaphragm passing part is adapted to allow the thoracic diaphragm to move during respiration, when implanted.

A muscle-powered pulsation device for cardiac support including a muscle energy converter device including a piston arrangement for directing fluid out of an outlet of the muscle energy converter device using energy provided by a patient's muscle, and a hydraulic volume amplification device fluidly connected to the muscle energy converter device. The volume amplification device includes a casing including an inlet and an outlet, the inlet in fluid communication with the outlet of the muscle energy converter device, at least one resilient member positioned within an interior cavity defined by the casing, and at least one piston member movably and sealingly positioned within the interior cavity of the casing and operatively connected to the at least one resilient member, the at least one piston member separating the interior cavity into a first chamber and a second chamber.

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 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 dysfunction, 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 or for healing.

An implantable device for improving the pump function of the heart of a human patient by applying an external force on the heart muscle. The device comprises at least one pump device comprising a heart contacting organ, an operating device for operating the heart contacting organ, and an implantable pressurized fluid system. The fluid system comprises a first implantable chamber adapted to hold a pressurized fluid, wherein said first chamber is adapted to hold a fluid having a high pressure and a second implantable chamber adapted to hold a pressurized fluid, wherein said second chamber is adapted to hold a fluid having a lower pressure. The movement of the heart contacting organ assists the pump function of the heart.

The present invention provides an implantable cardiac compression device comprising: an inflatable cardiac compression jacket configured when inflated to directly compress a heart and assist in displacing blood therefrom, a channel that connects the inflatable cardiac compression jacket and an expandable fluid reservoir configured to contain a fluid when displaced compresses the inflatable cardiac compression jacket, and a fluid driver operably connected to the inflatable cardiac compression jacket and to the expandable fluid reservoir, wherein the fluid driver is configured to inflate the cardiac compression jacket and to deflate the expandable fluid reservoir during systole of the heart; said driver is further configured to deflate the cardiac compression jacket and to inflate the expandable fluid reservoir during diastole of the heart.

A system and method for determining the proper dynamic strain profile of an elastomeric construct. The strain characteristics of a deficient heart are determined and compared to the normal strain characteristics of a healthy heart. A construct having elastomeric elements is provided that can expand along multiple axes. In an unloaded condition remote from the deficient heart, the elastomeric elements are pressurized to determine the pressure differential being experienced. Furthermore, optimal strain characteristics are calculated along a first axis and a second axis as a function of the pressure differential. The first optimal strain characteristic and the second optimal strain characteristic are used to estimate the dynamic strain characteristics that will be applied to the heart. The dynamic strain characteristics are compared to the optimal strain characteristics required by the heart to determine if the construct is proper using an automated drive.
