Abstract: Methods and devices for biasing a balloon catheter are disclosed. In one example, a medical device may include a catheter shaft and a balloon assembly coupled to a distal region of the catheter shaft. The balloon assembly can define a chamber configured to be inflated and deflated using a fluid supplied from the catheter shaft. A biasing member may be positioned in the chamber of the balloon assembly and may be configured to bias the balloon assembly to a longitudinally extended state without obstructing an exhaust lumen of the catheter shaft. In some cases, the biasing member may be a spring. In other cases, the biasing member may be a coiled portion of a fluid supply line.

Abstract: A catheter can include a shaft; an inflatable balloon having a proximal end that is anchored to an end of the shaft; an elongate member that is separate from and disposed inside the shaft, extends into an interior chamber of the balloon, and is anchored to a distal end of the balloon; and a spring member that exerts a distally-oriented longitudinal force on the elongate member, relative to the shaft, where the distally-oriented longitudinal force causes the balloon to be biased in an extended position, away from the end of the shaft. The catheter can further include a sheath that surrounds the shaft and balloon before a treatment procedure. The balloon can be configured to be advanced outside the sheath during a treatment procedure and inflated, and the spring member can be configured to facilitate deflation and withdrawal of the balloon into the sheath following the procedure.

Abstract: An electrophysiology system comprises an ablation catheter, a radiofrequency generator, and a mapping processor. The ablation catheter has a tissue ablation electrode and a plurality of microelectrodes distributed about the circumference of the tissue ablation electrode and electrically isolated therefrom. The plurality of microelectrodes define a plurality of bipolar microelectrode pairs. The mapping processor is configured to acquire output signals from the bipolar microelectrode pairs, compare the output signals, and generate an output to a display providing a visual indication of a characteristic of the microelectrodes and the tissue ablation electrode relative to myocardial tissue to be mapped and/or ablated.
