Abstract

The invention is entitled "Basket Catheter with Prestrained Frame". The present invention discloses a catheter having a basket-shaped electrode assembly at the distal end of the catheter body, the basket-shaped electrode assembly being formed from a plurality of spines with electrodes. The plurality of ridges may be formed by a frame that is pre-strained to have a diameter greater than a diameter of the basket electrode assembly in an expanded arrangement and a length less than a length of the basket electrode assembly in an expanded arrangement.

Description

Technical field [0001] The present invention relates to an electrophysiological (EP) catheter for standarding and / or ablation in the heart. Background technique [0002] Now, a cardiac catheter including an electrophysiological sensor for labeled cardiac electromatics is often used to perform the standard of the potential in the heart. Typically, depending on the position in the heart and record the time-to-endogenation in the endocardius, it is then used to measure the local electrical sampling or partial activation time. Due to the time required to pass the myocardial conductive electrical pulse, the activation time of each point in the endocardiofer is different. The direction of the electrical conduction at any point at the heart is conventionally represented by the activation vector, which may be from the active time of the activation time. The propagation rate of any intention of the endocardius before the activation wave can be represented as a speed vector. Specturing t...
