Locating guide
First Claim
1. A target tissue site locating guide comprising:
- a body defining a major surface;
a first set of substantially radiopaque reference markers on the major surface of the body, wherein at least one reference marker of the first set extends in a first plane; and
a second set of substantially radiopaque reference markers extending laterally from the major surface of the body, wherein at least one reference marker of the second set extends in a second plane, the first plane being different than the second plane, and wherein at least two reference markers of the second set are arranged to be separated from each other along the major surface.

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.

26. A method comprising:
-
positioning a locating guide on a skin surface of a patient, wherein the locating guide comprises; a body defining a major surface; a first set of radiopaque reference markers on the major surface of the body, wherein at least one reference marker of the first set extends in a first plane; and a second set of radiopaque reference markers configured to extend laterally from the major surface of the body, wherein at least one reference marker of the second set extends in a second plane, the first plane being different than the second plane, wherein markers of one of the first set or the second set of radiopaque references markers are configured to extend away from the skin surface of the patient when the locating guide is positioned on the skin surface, and wherein at least two reference markers of the second set are arranged to be separated from each other along the major surface; generating an image of at least a portion of the locating guide and at least a portion of tissue of the patient proximate to the locating guide with a medical imaging device; and registering the image with an actual location on or within the patient based on at least one of the first or second reference markers. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
