摘要:
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.

The disclosure relates to a device for performing diagnostics and/or therapy and related kit, system, computer program, methods and computer readable mediums. The device of this disclosure has the advantages that the device does not need access to the pericardium and that the whole system including kit and device can be removed after diagnostics/therapy. A device for performing diagnostics and/or therapy of an organ in the thoracic cavity, comprising an organ support (10), which organ support (10) is devised to be arranged exterior to an organ, and comprises: a flexible structure (14), such as a fabric, net, coil, bag or mesh, which is configured to cover a region of the organ, the region comprising at least the surface at an apex of the organ; at least one actuator (16), such as a motor, for actuating a movement of the flexible structure (14) for the therapy, and optionally at least one transducer (18), is provided.

The embodiments relate to cardiac assist devices that comprise a jacket that wraps the exterior of the heart, where the jacket comprises one or more pneumatic or hydraulic bladders. The pneumatic or hydraulic bladders are linked to a pump, and the pump fills the bladders with fluid and withdraws the fluid in a cycle to match beats of the heart to assist contraction and pumping of the heart in systole or to assist expansion and filling of the heart in diastole.

A device, a kit and a method are presented for permanently augmenting the pump function of the left heart. The basis for the presented innovation is an augmentation of the physiologically up and down movement of the mitral valve during each heart cycle. By means of catheter technique, minimal surgery, or open heart surgery implants are inserted into the left ventricle, the mitral valve annulus, the left atrium and adjacent tissue in order to augment the natural up and down movement of the mitral valve and thereby increasing the left ventricular diastolic filling and the piston effect of the closed mitral valve when moving towards the apex of said heart in systole and/or away from said apex in diastole.

Devices, systems, and methods for accessing tissue, including the internal and external tissues of the heart, are disclosed. At least some of the embodiments disclosed herein provide access to the internal and external tissues of the heart to assist heart function. In at least one embodiment, a suction/infusion catheter is used to deliver gas to a pericardial space surrounding a heart.

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. The implantable device comprises at least one implantable pump device comprising: A fluid, A first reservoir having a first volume and at least one movable wall portion, for varying said first volume, and A second reservoir being in fluid connection with said first reservoir. Wherein said implantable pump device is adapted to allow free flow of fluid between said first reservoir and said second reservoir, and wherein said first reservoir, said second reservoir and said fluid connection forms a fully implantable closed pump device, and wherein said fully implantable closed pump device is adapted to transfer force from said first reservoir to said second reservoir.

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. The device comprises at least one pump device which in turn comprises a rotating member having a rotating center. The rotating member could be a shaft or rod. A driving member could be attached to the rotating member and adapted to perform an eccentric movement in relation to the rotating center of said rotating member. The eccentric movement performed by the rotating member is adapted to exert an external force on the heart muscle through a heart contacting organ which is in contact with the driving member.
摘要:
The invention relates to and describes a device (1) for supporting and/or take-over of the pumping function of the heart (2), having a multi-layer sheathing part (3) being configured for the compression of the heart (2) at least in some regions, wherein the sheathing part (3) has at least one stabilizing layer (4) for forming the sheathing part (3), and at least one inner, stretchable augmentation layer (5), and wherein at least one hollow space (6) is formed between the stabilizing layer (4) and the augmentation layer (5) for the cyclic compression of the heart (2), said hollow space being inflatable and deflatable by means of a fluid. The invention provides that the stabilizing layer (4) can be inflated by means of a fluid, at least in some regions, in order to convert the sheathing part (3) from a rolled-up and/or folded insertion state during the insertion of the device into the body into an arched functional state, wherein the heart (2) is at least partially sheathed and/or encompassed by the sheathing part (3) in the functional state.
