Abstract:
1. A tissue-localizing device comprising: a sleeve having a lumen; an insulating layer at least partially covering an outer surface of the sleeve; a locator element at least partially disposed in the lumen of the sleeve in a slidable manner, the locator element having a distal portion and a distal end, the locator element further having at least a first surface and a second surface; a first electrically conductive surface region disposed at the distal end of the locator element and at least partially on the first surface and at least partially on the second surface; and at least a second electrically conductive surface region disposed at least partially along a length of the distal portion of the locator element and at least partially on the first surface and at least partially on the second surface, the locator element further adapted to penetrate tissue so that the distal portion of the locator element forms at least a partial loop that defines a volume of tissue when the locator element is deployed in tissue.
