1. A method for localizing a target tissue, comprising the steps of:
- determining the location of the target tissue;
passing a distal end of an elongate localization device through the patient'"'"'s skin and to the target tissue to create a tissue track between the patient'"'"'s skin and the target tissue, the localization device comprising a tubular mesh anchor element secured to a placement device, the placement device extending from the tubular mesh anchor element, along the tissue track and through the patient'"'"'s skin;
locating the tubular mesh anchor element at the target tissue;
expanding the tubular mesh anchor element from a contracted to an expanded configuration; and
wherein the cross-sectional area of the tubular mesh anchor element in the expanded configuration is at least four times the cross-sectional area in the contracted state.

Abstract
A target tissue localization device includes a tubular mesh anchor element that is secured to a placement device. In use, the localization device is passed through the patient'"'"'s skin to the target tissue, creating a tissue track. The tubular mesh anchor element is located at the target tissue and expanded from a contracted to an expanded configuration. Methods for localizing a lymph node are also described. After determining the position of the lymph node, a localization device, which includes an anchor element, is localized near or within the lymph node. The anchor element is then expanded.
