Ablation method

摘要

A method of ablating a uterine fibroid using a particular trocar is disclosed. The trocar comprises a plurality of ablation stylets. The trocar is adjustable to assume a plurality of configurations, each of the configurations having the stylets extended to a different extent from the trocar. A region to he ablated is imaged, The size of the region to be ablated is noted. The size of the region to be ablated is compared to a matrix of known ablation regions, each of the known ablation regions being associated with one of the configurations of the particular trocar. The region to be ablated is associated with a most nearly matching known ablation region by comparison of the region to be ablated to the known ablation regions. A trocar is inserted into the uterine fibroid at a position, which more closely matches the position of the particular trocar with respect to the known ablation region. The stylets are deployed from the trocar to an extent corresponding to the configuration.

1. A method of ablating a region of a uterine fibroid, comprising:
(a) employing a trocar comprised of a plurality of ablation stylets, an arrangement of ablation elements, and a trocar point, said trocar being adjustable to assume a plurality of configurations; (b) imaging a region to be ablated; (c) noting size of the region to be ablated; (d) comparing the size of the region to be ablated to a matrix of known ablation regions, each of the known ablation regions being associated with one of the configurations of the trocar, each of the known ablation regions being associated with a position of the trocar relative to the known ablation region; (e) associating the region to be ablated with a most nearly matching known ablation region by comparison of the region to be ablated to the known ablation regions; (f) inserting the trocar with effectively the same arrangement of ablation elements and trocar point into the uterine fibroid at a location which most closely matches the location of the trocar at the known ablation region; and (g) deploying the stylets from the trocar to an extent corresponding to the configuration associated with the most closely matching known ablation region.
