Heart help device, system, and method
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.
Access Device And System For A Heart Including A Cardiac Assist Unit
An access device for a heart chamber, a removable hemostatic valve unit, and a system including a cardiac assist unit are disclosed. In examples, the access device) includes an apical base plate and a sealing unit configured to provide a separation of a wet zone from a heart chamber and a dry zone with a gaseous environment outside of said heart chamber inside a patient body at the same time.
Left atrial appendage stasis reduction
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.
MECHANICAL CARDIAC RESYNCHRONIZATION THERAPY DEVICE
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.

Direct Cardiac Compression Device with Improved Durability
The present invention provides a direct cardiac compression device comprising one or more passive chambers that taper from an aperture to an apex; one or more inflatable active pockets individually independently inflatable, wherein each of the one or more inflatable active pockets is connected to the one or more passive chambers at least partially from the aperture to the apex and wherein the each of the one or more inflatable active pockets does not tension the adjacent one or more inflatable active pockets upon inflation; and a frame in contact with the one or more active chambers to at least partially surround the one or more active pockets.
Cardiac treatment system
A cardiac device for implantation proximate an exterior of a heart, the cardiac device including an inflatable bladder including an inner wall and an outer wall, wherein the inner wall itself is more expandable than the outer wall itself such that the inflatable bladder itself is configured to deform substantially inwardly to exert localized pressure against a region of the heart when the inflatable bladder is positioned adjacent the region of the heart and inflated.
