LINEAR MOTION, MUSCLE-ACTUATED CARDIAC ASSIST DEVICE |
摘要 |
A linear motion, muscle-actuated cardiac assist device novelly uses a powering muscle whose contractions and relaxations are made in a substantially linear fashion, as opposed to the curvilinear muscle motions associated with prior art muscle-actuated cardiac assist devices. As a result, collateral circulation of the powering muscle need not be cut, theoretically leading to prevention of ischemia in the powering muscle. Other benefits include: greater energy efficiency of the powering muscle; greater available choice of powering muscles (i.e., not limited to the latissimus dorsi as the powering muscle); and reduced profile height of the cardiac assist device to reduce protrusion from the implanted area of the body. |
