摘要：
Apparatus and methods are described, including apparatus for puncturing a fossa ovalis of a heart. The apparatus includes a catheter shaped to define a catheter lumen. A puncturing element is slidably disposed within the catheter lumen, and is deployed from a distal portion of the catheter and to puncture the fossa ovalis. A probing element is deployed from the distal portion of the catheter. Upon being deployed, the probing element probes tissue near the fossa ovalis, the probing element having a first configuration thereof upon probing the tissue near the fossa ovalis. Upon probing tissue of the fossa ovalis, the probing element facilitates positioning of the puncturing element, by automatically adopting a second configuration thereof that is different from the first configuration. Other applications are also described.
