摘要： A catheter for ablating body tissue of the interior regions of the heart includes a handle assembly, a shaft, and a distal tip section coupled to the distal end of the shaft. The distal tip section has a non-compliant and non-porous cap that has a tubular wall that defines a bore, and an ablation element that is housed inside the bore and spaced apart from the wall of the cap.

摘要： The disclosure relates to a variety of systems and methods for sensing electrical events about a selected annulus region of the heart and for treating tissue in the selected annulus region. Wherein the system includes a first catheter that has an expandable member, an ablation element, and a lumen configured to allow a second catheter therethrough. The second catheter includes a distal section in a ring shape and a plurality of electrodes coupled around the ring. Optionally a second lumen can be included through the first catheter that allows for contrast media to be delivered to the distal end of the system.

摘要： Embodiments of the present invention provide a catheter that comprises an elongated catheter body (16) and an electrode assembly (10) at the distal end of the catheter body. The electrode assembly comprises a plurality of spines (11), each of the spines having a proximal end connected to the distal end of the catheter and a distal end, the distal ends of the spines being connected at a spine tip junction (13). Each spine includes an elbow (20) having at least one discontinuity in stiffness at an intermediate position between the distal end and the proximal end thereof. The spines include a plurality of electrodes (12). The electrode assembly is collapsible to a collapsed arrangement to fit within a lumen of the elongated catheter body and expandable to an expanded arrangement with the elbows of the spines bending outwardly relative to the proximal and distal ends of the spines.
