Abstract
A locating guide for locating a target tissue site within a patient includes a body, a first substantially radiopaque reference marker on the body, and a second substantially radiopaque reference marker extending from a major surface of the body. The reference markers provide reference points that extend in at least two dimensions, and may be useful for registering a medical image of tissue with an actual location on or within the patient in order to more accurately and precisely locate a target tissue site within the patient. In some embodiments, the second reference marker is oriented at a predetermined angle relative to the major surface of the body, and provides a guide that a clinician may reference in order to orient a medical element introducer when introducing the introducer into the patient to access a particular target tissue site.
