    摘要： Systems and methods are disclosed for assessing electrode-tissue contact for tissue ablation. An exemplary electrode contact sensing system comprises an electrode 10 housed within a distal portion of a catheter shaft 14. At least one electro-mechanical sensor 20 is operatively associated with the electrode 10 within the catheter shaft 14. The at least one electro-mechanical sensor 20 is responsive to movement of the electrode 10 by generating electrical signals corresponding to the amount of movement. The system may also include an output device electrically connected to the at least one electro-mechanical sensor 20. The output device receives the electrical signals for assessing a level of contact between the electrode 10 and a tissue 12.

    摘要： Acoustic coupling systems and methods are disclosed as these can be used for assessment and ablation procedures. An exemplary acoustic assessment system for a catheter may comprise a flexible catheter shaft. At least one acoustic transducer is positioned in the flexible catheter shaft. The at least one acoustic transducer emits a generated acoustic signal for reflection by adjacent tissue. The at least one acoustic transducer receives a reflected acoustic signal from the adjacent tissue and generates electrical signals corresponding to one or more property of the tissue. An output device is electrically connected to the at least one acoustic transducer. The output device receives the electrical signals and generate output for a user for assessing the tissue.
