    摘要： Ablation instruments and methods are disclosed for ablating diseased tissue such as cardiac tissue. The ablation device can remotely apply ablative energy to biological tissue and comprises a flexible elongate member having a proximal end, a distal end and a longitudinal lumen extending therebetween. An energy emitting element is disposed within the longitudinal lumen of the flexible elongate member. The energy emitting element has a proximal end and a distal end for emitting energy along at least a portion of its length. The device is configured to emit a variable amount of energy along a length of the flexible elongate member. The method includes introducing the flexible elongate member into a predetermined tissue site to ablate a target tissue. The target tissue is ablated, coagulated or photochemically modulated without damaging surrounding tissue.

    摘要： Embodiments of the present invention provide systems and methods for assisting with contraction of the heart muscle. For example, in one embodiment of the invention, one or more flexible strips are attached to the surface of the heart, each strip having a plurality of electromagnets alternating with a plurality of permanent magnets. The electromagnets are electrically coupled to a control device and a power supply for generating current in the electromagnets. The control device controls the current in the electromagnets in such a way that the electromagnets are periodically activated to attract the adjacent permanent magnets to assist with contraction of the heart muscle. In some embodiments a sensor is provided for sensing the sinus rhythm so that the control device can activate the electromagnets based on the sensed sinus rhythm.
