Patent ID: 6872213

Claim:
A method of placing a probe or defining a vector from outside a tissue into a target area located within said tissue using an imaging device, said target area being within reach of said probe from a targeting surface of said tissue, said method comprising: (1) establishing a lower plane substantially at said surface of said tissue, said lower plane comprising a lower vector point, and said lower plane portion comprising a lower plane template comprising a pair of angled members of an imager-conspicuous material, each of said pair of angled members defining an angle of about 53 degrees; (2) establishing an upper plane above said surface of said tissue, said upper plane comprising an upper plane template comprising a pair of adjacent angled members comprising an imager-conspicuous material, said pair of adjacent angled members aligned such that said pair of adjacent angled members open in substantially parallel directions, and wherein said angle defined by each of said pair of adjacent angled members defines an angle of about 53 degrees; (3) providing an alignment structure comprising an upper vector point adapted to move parallel to said upper plane, so as to be able to define a vector passing through said upper and lower vector points; (4) if not so aligned, aligning said upper plane and lower plane templates such that said image plane of said imaging device is aligned perpendicular to said bisectors of each of said adjacent angled members; (5) determining the position of said target area with respect to an entrance point through said lower plane template; (6) adjusting said alignment structure so as to form a vector containing said entrance point and a point in said target area, and (7) passing said probe along said vector to said target area.
