Sphincter treatment apparatus
View Patent ↗A sphincter treatment apparatus includes an elongated member having at least one lumen including an inflation lumen and a basket assembly with first and second arms. The basket assembly is coupled to the elongated member and has deployed and non-deployed configurations. An inflatable member is coupled to the elongated member and positioned in an interior of the basket assembly. The inflatable member has deployed and non-deployed states and is coupled to the inflation lumen. In the deployed state, the inflatable member expands the basket assembly to its deployed configuration. A first energy delivery device is positionable in the first arm and advanceable from the first arm to a selected treatment site. A second energy delivery device is positionable in the second arm and advanceable from the second arm to a selected treatment site.
1. A sphincter treatment apparatus comprising:
an elongated member having at least one lumen including an inflation lumen,
a basket assembly including a first and a second arm, at least one of the first and second arms including a fluid lumen having an aperture for conveying a fluid from the basket assembly, the basket assembly being coupled to the elongated member and having a deployed and a non-deployed configuration,
an inflatable member coupled to the elongated member and positioned in an interior of the basket assembly, the inflatable member being coupled to the inflation lumen, the inflatable member having a deployed and a non-deployed state, wherein in the deployed state the inflatable member expands the basket assembly to the basket assembly deployed configuration, and
an energy delivery device coupled to the basket assembly and configured to be advanceable into tissue to deliver energy to a selected treatment site.
2. The apparatus of claim 1
wherein the energy delivery device is positioned on an exterior surface of the basket assembly.
3. The apparatus of claim 1
wherein the energy delivery device is integral to the basket assembly.
4. The apparatus of claim 1
wherein the energy delivery device is disposed in the basket assembly.
5. The apparatus of claim 4
wherein the energy delivery device is disposed on an interior surface of the basket assembly.
6. The apparatus of claim 1
wherein the energy delivery device includes a tissue-piercing distal end.
7. The apparatus of claim 6
wherein the energy delivery device is a radiofrequency electrode.
8. The apparatus of claim 7
wherein the radiofrequency electrode is a needle electrode.
9. The apparatus of claim 7
wherein the energy delivery device includes a plurality of radiofrequency electrodes.
10. The apparatus of claim 1
wherein the fluid is a cooling fluid.
11. The apparatus of claim 10
wherein the fluid cools tissue adjacent the energy delivery device.
12. The apparatus of claim 10
wherein the fluid cools the energy delivery device.
13. The apparatus of claim 1
wherein the energy delivery device is advanceable from the at least one arm through the aperture.
14. The apparatus of claim 1
wherein the fluid is an electrolytic solution.
