摘要: Medical devices, systems, and methods for treating patients with tissue ablation include catheter systems having bi-modal steering mechanisms, which are capable of both linear and loop ablation. In other words, the catheter system may have two different steering modes: two-dimensional and three-dimensional. In the first and second steering modes, the steering actuator may cause one or more portions of the catheter shaft to bend in different planes. A steerable ablation catheter may include treatment elements such as electrodes at its distal end and along the catheter shaft, each of which may map, pace, and ablate.

摘要: A medical device is provided, including an elongate body defining a lumen therethrough; a shaft extending through the lumen; and an electrode array coupled to the elongate body at a first end and coupled to the shaft at a second end, where linear manipulation of the shaft causes the electrode array to transition from a first geometric configuration to a second configuration, and where rotational manipulation of the shaft causes the electrode array to transition from the second geometric configuration to a third configuration.
