Device for medical procedure localization and/or insertion
First Claim
1. A device for assisting, preparing for, or training for a medical procedure, said procedure entailing localization, incision, or insertion at a procedure site on a human patient, said device comprising:
- a locator base extending from a first end to a second end, said locator base having a shape at said first end configured to index contact with a first thoracic anatomical landmark defined by a sub-epidermal structure, and said locator base having a shape at said second end configured for visual or physical alignment with a second anatomical landmark that is caudad to said first thoracic anatomical landmark, said locator base thereby indexing a first reference point at said first thoracic anatomical landmark and a second reference point at said second caudad anatomical landmark, and a first axis extending between said first reference point and said second reference point;
a first movable member slidably attached to said locator base for movement along said first axis until alignment with a third anatomical landmark, said first movable member thereby indexing a third reference point at said third anatomical landmark, said third reference point being along a second axis that intersects said first axis; and
a guide for indicating said procedure site at an intersection of said first axis and second axis.

Abstract
A device (100) for medical procedure localization and/or insertion that can be dimensionally adjusted for different patient sizes and properly aligned and stabilized using anatomical landmarks. The device (100) for medical procedure localization and/or insertion provides an adjustable template that indexes the site of interest at the intersection of a first axis or plane and a second axis or plane. An embodiment is disclosed in which a first axis is the axillary line through the patient'"'"'s axilla (armpit) and iliac crest (pelvis), and a second axis is the patient'"'"'s ideal horizontal nipple line. The intersection of the first and second axes is the 4th or 5th intercostal space, into which a needle and/or chest tube may be placed for decompression.

27. A device for assisting percutaneous procedures on a human patient, comprising:
-
a base extending from a first end to a second end, said base having a first shape at said first end configured to index contact with a first thoracic anatomical landmark, said base having a second shape at said second end configured for visual or physical alignment with a second anatomical landmark that is caudad to said first thoracic anatomical landmark, said base thereby indexing a first reference point at said first thoracic anatomical landmark and a second reference point at said second caudad anatomical landmark, said first and second reference points being along and a first axis extending between said first reference point and said second reference point; at least one adjustable component attached to said base for linear sliding movement along said first axis until alignment with a third anatomical landmark along a second axis that intersects said first axis; and a guide that assists percutaneous access at a procedure site at an intersection of said first axis and second axis.

28. A device for assisting, preparing for, or training for a medical procedure, said procedure entailing localization, incision, or insertion at a procedure site on a human patient, said device comprising:
-
a locator base extending from a first end to a second end, said locator base having a first shape at said first end configured to index contact with a thoracic anatomical landmark and thereby indexing a first point, said locator base having a second shape at said second end configured for visual or physical indexing of an anatomical landmark that is caudad to said thoracic anatomical landmark and thereby indexing a second point, said first and second points being along a first axis extending between said first point and said second point; and a guide comprising an aperture through said locator base centered at an intersection of said first axis and a second axis that is offset from one of said thoracic anatomical landmark and caudad anatomical landmark and generally perpendicular to said first axis for indicating said procedure site. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)

36. A device for assisting, preparing for or training for a medical procedure, said procedure entailing localization, incision, or insertion at a procedure site on a human patient, said device comprising:
-
a locator base extending from a first end to a second end, said locator base having a first shape at said first end configured to index contact with a first thoracic anatomical landmark to thereby index a first point, said locator base having a second shape at said second end configured for visual or physical alignment with a second anatomical landmark that is caudad to said first thoracic anatomical landmark, said locator base thereby indexing a first reference point at said first thoracic anatomical landmark and a second reference point at said second caudad anatomical landmark, said first and second reference points being along a first axis extending between said first thoracic reference point and said second caudad reference point; a first movable member movably attached to said locator base for linear translation along said first axis; and a guide on said movable member for indicating said procedure site relative to said first axis, relative to at least one different anatomical landmark.
