Abstract
A device, a kit and a method is presented for permanently augmenting the pump function of the left heart. The mitral valve plane is assisted in a movement along the left ventricular long axis during each heart cycle. The very close relationship between the coronary sinus and the mitral valve is used by various embodiments of a medical device providing this assisted movement. By means of catheter technique an implant is inserted into the coronary sinus, the device is augmenting the up and down movement of the mitral valve and thereby increasing the left ventricular diastolic filling when moving upwards and the piston effect of the closed mitral valve when moving downwards.
Claims20
A medical device for mimicking at least a portion of left ventricular pump action in a heart of a patient comprising:
- a first anchor unit configured for implantation in a cardiac vessel of said heart in proximity to a mitral valve (MV) plane,
- a second anchor unit configured for implantation at a location different from said first anchor unit and in communication with said first anchor unit, and
- a powered force generating unit configured to generate anchor forces that move the first and second anchor units relative to each other in synchronicity with heartbeats.
A medical device for mimicking at least a portion of left ventricular pump action in a heart of a patient comprising:
- a first anchor unit configured for implantation in a cardiac vessel of said heart in proximity to a mitral valve (MV) plane,
- a second anchor unit configured for implantation at a location different from said first anchor unit and in communication with said first anchor unit, and
- a powered force generating unit configured to generate anchor forces that move the first and second anchor units relative to each according to a set sequence;
- wherein said set sequence comprises a first anchor force that moves said anchor units toward each other and a second anchor force moves said anchor units away from each other.
The device of claim 20, wherein said remote energy source is comprised of a mechanical section for generating at least one of a rotational motion and a linear motion, and an extension unit extending from said mechanical section, wherein said mechanical section is said force generating unit and wherein said motion is transferred in operation of said mechanical section to said first anchor unit for said assisted movement of said mitral valve plane via said extension unit.
