Abstract
Medical devices and methods for making and using the same are disclosed. An medical device may include a medical device for renal nerve ablation. The medical device may include a catheter shaft having a distal region. An expandable balloon may be coupled to the distal region. An electrode assembly may be coupled to the balloon. The electrode assembly may include a first electrode pad including one or more electrodes. The first electrode pad may have a first lead-in edge, a first protruding edge, and a first transition region with a continuously changing curvature disposed between the first lead-in edge and the first protruding edge.
Claims20
A medical device for renal nerve ablation, comprising:
- a catheter shaft having a distal region;
- an expandable balloon coupled to the distal region;
- an electrode assembly coupled to the balloon, the electrode assembly including a first electrode pad including one or more electrodes;
- wherein the first electrode pad has a first lead-in edge, a first protruding edge, and a first transition region with a continuously changing curvature disposed between the first lead-in edge and the first protruding edge.
A medical device for renal nerve ablation, comprising:
- a catheter shaft having a distal region;
- an expandable balloon coupled to the distal region;
- an electrode assembly attached to an outer surface of the balloon, the electrode assembly including a distal electrode pad including a first pair of bipolar electrodes and a proximal electrode pad having a second pair of bipolar electrodes;
- wherein a proximal tail extends proximally from the proximal electrode pad;
- and
- wherein the proximal electrode pad is centered with the proximal tail.
A medical device for renal nerve ablation, comprising:
- a catheter shaft having a distal region;
- an expandable balloon coupled to the distal region;
- an electrode assembly attached to an outer surface of the balloon, the electrode assembly including a first electrode pad including a first pair of bipolar electrodes and a second electrode pad having a second pair of bipolar electrodes;
