Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a catheter for use in cardiac mapping and/or ablation. The catheter may include an elongate catheter shaft having a distal ablation electrode region capable of ablating tissue. An electrode assembly may be coupled to the distal ablation electrode region. The electrode assembly may include a flexible circuit having one or more electrodes disposed thereon.

Medical devices with a flexible electrode assembly coupled to an ablation tip

An expandable electrode assembly for use in a cardiac mapping procedure includes multiple bipolar electrode pairs including a first electrode located on an outer surface and a second electrode located on an inner surface of the individual splines forming the expandable electrode assembly. Such an electrode arrangement may produce improved electrical activation signals which may be used to produce a more accurate map of the electrical activity of a patient's heart.

Electrode assembly

A catheter including expandable electrode assembly having a distal cap that mechanically engages a locking feature provided on the distal ends of each of two or more flexible splines forming a portion of the expandable electrode assembly is described. The distal cap defines an atraumatic distal tip of the catheter. The catheter may be used in a cardiac mapping and/or ablation procedure.
