Abstract
A sphincter treatment apparatus has an introducer means including a distal portion means. An expandable device means includes a plurality of arm means. Each arm means of the plurality has a distal section means and a proximal section means. Each of distal sections means of the arm means are coupled and each of the proximal sections means of the arm means are coupled to the introducer means distal portion means. The expandable device means is configured to at least partially dilate a sphincter in a deployed state. An energy delivery device means is introduceable from the introducer means into a selected site of the sphincter. The energy delivery device means is configured to deliver sufficient energy to reduce a frequency of relaxation of the sphincter.
Claims11
A sphincter treatment apparatus comprising:
- an introducer having an introducer lumen,
- an expandable device coupled to the introducer, the expandable device including a first arm with a proximal section and a distal section and a second arm with a proximal section and a distal section, the first and second arm distal sections being coupled, at least one of the first and second arms including an arm lumen coupled in fluid communication with the introducer lumen for delivery of a fluid, the expandable device being configured to at least partially dilate a sphincter in a deployed state, and
- an energy delivery device coupled to the expandable device.
A method of treating a sphincter comprising:
- providing an introducer, the introducer carrying an expandable device,
- providing an energy delivery device coupled to the expandable device,
- deploying the introducer to a targeted tissue site at or near a sphincter,
- expanding the expandable device to at least partially dilate the sphincter,
- delivering energy from the energy delivery device to the targeted tissue site, and
- delivering a cooling fluid from the introducer.
