System and method for treating tissue using an expandable antenna |
| 摘要 |
An ablation device includes an antenna assembly having a radiating portion configured to deliver energy from a power source to tissue of a patient. The radiating portion has an outer conductor and an inner conductor extending therethrough. The inner conductor is disposed within the outer conductor and defines a longitudinal axis. One of the inner conductor and the outer conductor is movable relative to the other to cause at least a portion of the outer conductor to expand radially relative to the longitudinal axis. |

1. An ablation device, comprising:
an antenna assembly having a radiating portion configured to deliver energy from a power source to tissue of a patient, the radiating portion defining a longitudinal axis and having an outer conductor and an inner conductor disposed within the outer conductor and separated by a dielectric material disposed on the inner conductor; wherein one of the inner conductor or the outer conductor is movable relative to the other to cause at least a portion of the outer conductor to expand radially relative to the longitudinal axis. |
