摘要:
An intra-cardiac medical device adapted to enhance intra-cardiac blood circulation of a heart of a patient by assisting left ventricular pump action, said device having a blood displacement unit adapted to circulate blood from the left ventricle to the aortic valve by displacement of blood in the left atrium and/or left ventricle towards an apex of the heart and/or to said aortic valve, thus assisting left ventricular pump action.
摘要:
A medical device is disclosed that is adapted to enhance intra-cardiac blood circulation of a heart of a patient by assisting pump action of said heart. The device includes a fixation unit for fixating a mechanical unit of said device to a cardiac valve annulus. The mechanical unit is devised to apply a mechanical supporting force to the valve annulus during at least a portion of systole for augmenting the natural pumping force of the heart, and/or during at least a portion of diastole for augmenting a natural filling of the ventricle of said heart. The fixation unit is for instance at least partly loop shaped and adapted to be affixed to the valve annulus, and wherein said mechanical unit is attached to said fixation unit at a circumference of said fixation unit.
摘要:
An implant for assisting contraction and/or extension of a muscle comprises a stem (10) with an adhesion resistant segment (14) and an anchoring segment (20) wherein at least a portion of each of said adhesion resistant segment and said anchoring segment is configured to be implantable within a muscle and said anchoring segment is positioned on a distal portion of said stem and said adhesion resistant segment is positioned proximally on said stem relative to said anchoring segment.
摘要:
An intra cardiac device transforms kinetic energy from heart tissue movement into electrical energy to power the device and provide information in respect of heart function. A system comprising such an intra cardiac device may communicate wirelessly with at least one receiver outside the body and may be used for conveniently monitoring or stimulating a patient's heart.
摘要:
An implantable hydraulic displacement actuator comprising a biocompatible hydraulic displacement fluid for providing a force inside a human or animal body, wherein said hydraulic displacement actuator preferably is a linear hydraulic actuator for generating a cardiac movement.
