The present invention relates to a medical chamber system (700) for implantation in the chest of a patient to support the heart activity, preferably by displacing the heart apex (105), comprising at least a first chamber (702) for arrangement inside the heart sac (300) and a second chamber (701) for arrangement outside the heart sac (300), wherein the chambers (701, 702) comprise at least one connection portion or connection channel (703) which connects the two chambers (701, 702) to each other, the chambers (701, 702) and the connection channel (703) are further embodied to be filled with fluid (705) and, preferably in the implanted state, to be arranged such that the heart activity acts on the first chamber (702) and that the second chamber (701) acts as a volume storage and/or energy storage for the fluid (705). Furthermore, the present invention relates to an introduction system for a medical chamber system (700) and to a kit, encompassing a medical chamber system (700) and an introduction system.

A system and method are disclosed in the field of preparing a catheter for use in a patient, in particular a catheter of an intravascular blood pump, more specifically for properly purging and de-airing the catheter. The catheter comprises an elongate tubular portion and a connected device. The elongate tubular portion is configured to be inserted into a patient's blood vessel and defines a lumen. The connected device is connected to the elongate tubular portion and has a cavity, which may accommodate a drive unit of the blood pump, and which is in fluid communication with the lumen of the elongate tubular portion. In order to securely de-air the system, a sensor, such as an accelerometer, for detecting an orientation of the connected device is provided, and a user may be guided to correct the orientation of the connected device for proper purging.

The present invention relates to surgical or laparoscopic method of creating and maintaining an opening in the thoracic diaphragm of a patient. In said method, an incision in the thoracic diaphragm is created, thereby creating an opening in the thoracic diaphragm. Further a diaphragm passing part is placed in said opening created in the thoracic diaphragm, passing from the abdomen, through the thoracic diaphragm at the pericardial contacting section, into the pericardium; When placing the diaphragm passing part a force transferring part of the diaphragm passing part is placed in contact with the thoracic diaphragm, the force transferring part being adapted to, by motion of the force transferring part, transfer force between the abdominal side of the thoracic diaphragm and the thoracic side of the thoracic diaphragm or the pericardium while sliding against the thoracic diaphragm.

Systems and methods for determining the positioning of intracardiac devices, such as intracardiac blood pump assemblies, using electrical sensors configured to sense electrical potential as it propagates through the heart. In one example, the present technology provides an intracardiac device with one or more electrical sensors mounted thereon, and a controller configured to determine the absolute or relative location of the intracardiac device based on the timing, shape, and/or amplitude of the electrical signals received from the one or more sensors.

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.

A percutaneous circulatory support device includes a housing, an impeller disposed within the housing and being rotatable relative to the housing, through the housing, and out of the outlet, a cannula coupled to the housing, the cannula having a body extending between a proximal end and a distal end and along a longitudinal axis, a structural body portion, a surface coating disposed onto the structural body portion of the cannula, and a channel defined between the structural body portion of the cannula and the surface coating, and a pull wire coupled to the cannula and extending through the channel of the cannula. Manipulation of the pull wire causes a change in shape profile of the cannula body.
