A smart cardiac assist device which may aid in ventricular recovery. The device proactively assists the left and the right ventricular chambers to contract and relax better. The device includes a plurality of sensors to understand the native cardiac function in real time and assist the heart as per its requirement and support required in real time.

Disclosed are techniques to generate ideal or near ideal profiles for regulation of the volume of fluid flow in a drive system of a pump for an externally mechanically supported heart, pressure in or near the pump, or measured strain/strain rates of the supported heart, based on an estimate/measurement of the heart's size. A part of the techniques for regulation may focus on achieving mechanical synchrony with the intrinsic cyclic pump function of a partially functional heart. The techniques do not fundamentally rely on hemodynamic measurements to function. However, when hemodynamic measures are available, those measures can be fed to control algorithms to increase the efficacy of regulation to restore the heart's pump function.

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, the operation device comprises an electrical motor comprising a static part comprising a plurality of coils and a movable part comprising a plurality of magnets, such that sequential energizing of said coils magnetically propels the magnets and thus propels the movable part. The operation device further comprises an enclosure adapted to hermetically enclose the coils of the static part, such that a seal is created between the static part and the propelled moving part with the included magnets, such that the coils of the static part are sealed from the bodily fluids, when implanted.

A first drive unit, in a state where a top end of a tubular joint is interposed into a chest of a target person and is located at a lower heart part, pushes a diaphragm out from the top end of the tubular joint while pressing a gas into the diaphragm, and simultaneously causes the diaphragm to start flexing to cover and wrap the lower heart part, and then stops pressing the gas into the diaphragm at a time point where compression balloons are positioned at atriums and ventricles of a heart, respectively; and second drive units support a pumping function of the heart by alternately repeating an ejecting operation to fill each of the compression balloons with a fluid and cause each compression balloon to expand and an absorbing operation to cause each compression balloon to discharge the fluid and contract.

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.

Methods and apparatuses relate to an implantable device for providing contractile assistance to an organ. The device may include an actuator and anchors located on either side of the actuator. The anchors engage with oppositely positioned tissue walls of an organ chamber, and provide contractile assistance to the organ, repeatedly, at appropriate times. For example, the device may be implanted within the right ventricle, anchored to the right ventricular free wall and the ventricular septum. The device may function to bring the opposing walls of the ventricle toward one another, synchronized with the pacing of the heart, resulting in an improved ejection fraction of blood from the chamber. In some embodiments, the actuator includes a bladder that is configured to contract upon receiving an inflow of pressurized fluid therein. When the fluid exits therefrom, the bladder relaxes back to an initial, extended state.

An implantable medical device for transcatheter delivery, which includes an anchor unit (100) configured to be anchored at an annulus of a cardiac valve of a patient, at least one coupling unit (200) that extends along a first length radially from said anchor unit (100) towards a coaptation line of said valve and including an extension unit (400) extending along a second length. The extension unit (400) is configured to cross between the leaflets of the cardiac valve in order to fill out for an insufficient closing of the valve leaflets of said cardiac valve.

The present invention relates to method for implanting a medical device for controlling a flow of fluid in a lumen formed by a tissue wall of a patient's urethra. The method is performed by: cutting the skin of the patient, inserting a dissecting tool and dissecting an area of at least one portion of the tissue wall of the urethra, placing an adjustable constriction device in the dissected area in operative engagement with the urethra, placing an operation device configured to operate the adjustable constriction device to control the flow of urine in the urethra in the patient's body, placing a sensor configured to sense a temperature of the medical device in the patient's body, and placing a control unit in the patient's body configured to control the operation device based on information from the sensor.

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 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, a second reservoir, 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.

Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patients superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patients Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.
