发明名称 | Device, system and use of a catheter system to record and map cardiac rhythm | ||
解决的技术问题 | The disclosure is believed to provide for an intra-cardiac signal capture device with an increased number and higher density of electrodes to facilitate more reliable identification of targets during procedures, as well as an electrophysiology catheter with closely-spaced microelectrodes for high electrode density that is believed to be clinically effective. This disclosure allows for a electrophysiology catheter having electrode-carrying structures that are delicate in construction to provide desired flexible yet be predictable in their movement upon tissue contact. The disclosure also provides for a electrophysiology catheter that is constructed in a manner that minimizes the risk of components detaching, kinking and tangling, and reinforces the spine construction to minimize deformation, including elongation of soft spine covers and of microelectrodes carried thereon. | ||
技术方案 | A catheter system to record and map electrical signals by cardiac tissues before, during, and/or after the treatment of cardiac arrhythmias in a group of patients. The system can include an elongated body; a distal electrode assembly comprising a proximal stem, a plurality of spines emanating from the stem; and a plurality of nonconductive spine covers, each surrounding a respective spine. Each spine can cover one or more tensile members of the respective spine cover. The system can be configured to achieve clinically improved performance and safety of catheter configurations as to accessibility into target areas of a beating heart. | ||
