Abstract
An apparatus for transferring location and/or trajectory information from a reference surface to a patient tissue surface for guiding placement of a landmark includes a landmark guiding structure. At least two locating feet are provided, each being laterally spaced from, and indirectly connected to, the landmark guiding structure. A holdaway structure is connected to each locating foot and to the landmark guiding structure. The landmark guiding structure is placed in desired location and/or a desired trajectory with respect to the reference surface. Each locating foot is adjusted into guiding contact with a particular portion of the reference surface. Each locating foot is maintained in the guiding contact position, and the apparatus is placed with each locating foot in guiding contact with a particular portion of the patient tissue surface. A method of transferring location and/or trajectory information from a reference surface to a patient tissue surface is also disclosed.
