Abstract:
Catheter devices can include an elongate housing extending along a major axis, the elongate housing comprising a first end an opening. The catheter devices can also include an electrode assembly disposed in the elongate housing and including deformable electrodes with respective electrode distal ends, where the electrode distal ends each consist of respective member portions and respective tip portions. The electrode assembly is slidably movable within the housing along the major axis to allow the electrode distal end portions to transition between a first retracted position and a second extended position. The catheter device is configured such that an average distance between the tip portions in the second position is configured to be greater than an average distance between the tip portions in the first position the tip portions are positioned substantially in a same plane when the electrode assembly is in the second position.
