发明名称 Cardiac tissue elasticity sensing
摘要 A system and method are provided for assessing the compliance of internal patient tissue for purposes of catheter guidance and/or ablation procedures. Specifically, the system/method provides for probing internal patient tissue in order to obtain force and/or tissue displacement measurements. These measurements are utilized to generate an indication of tissue elasticity. In one exemplary embodiment, the indication of elasticity is correlated with an image of the internal tissue area and an output of this image including elasticity indications is displayed for a user.

主权项 1. A method, comprising: receiving a first force signal from a catheter as the catheter is displaced relative to an internal tissue location; receiving a first displacement signal indicative of movement of the catheter between a reference position and the internal tissue location; and processing said first force signal and said first displacement signal to generate a tissue characteristic value for the internal tissue location.
