Devices, systems and methods are disclosed for the ablation of tissue. A steerable ablation catheter can include one or more ablation elements at its distal end and one or more ablation elements fixedly attached to its shaft. The distal end of the ablation catheter can be deflected to assume a number of different deflection geometries in at least one direction along the shaft. One feature of the ablation catheter is that its shaft can comprise materials of differing durometers or stiffnesses attached together at a joint. Methods associated with use of the ablation catheter are also covered.

RF energy delivery system and method

An expandable balloon for a medical device having a static state, at least one first expanded state, and at least one second expanded state, the expandable balloon having a substantially polygonal geometric shape in the static state.

Balloon folding design and method and apparatus for making balloons

A catheter balloon may include a proximal waist portion, a proximal cone portion, a first body portion, a second body portion, a third body portion, a distal cone portion and a distal waist portion. The second body portion may comprise a stepped-down section. An inflated diameter of the second body portion may be less than an inflated diameter of the first body portion or the third body portion. An outer surface of the second body portion may be provided with at least one implement, such as a blade or stiffening member.
