TARGETING OBTURATOR
A medical targeting device includes an elongated body member extending between a distal end and a proximal end. In one embodiment, a three-dimensional targeting region is formed adjacent to the distal end such that the targeting region is formed to be substantially co-planar with an outside surface of the body member. The targeting region further includes a contrast agent. A method for using the medical targeting device is also disclosed.
1 . A medical targeting device, comprising:
an elongated body member extending between a distal end and a proximal end;
a three-dimensional targeting region formed adjacent to said distal end, wherein said targeting region is formed so as to be substantially coplanar with an outside surface of said body member and having a portion that extends inwardly therefrom into a portion of said body member; and
wherein said targeting region includes a contrast agent.
2 . The device of claim 1 , wherein said body member further comprises a generally centrally located longitudinal axis extending therethrough and wherein said targeting region is radially offset from said axis.
3 . The device of claim 1 , wherein said body member is generally cylindrical and said targeting region includes an elongated arcuate volume.
4 . The device of claim 3 , wherein said arcuate volume includes:
a substantially rectangular base portion defined by first and second generally longitudinally extending edges and first and second generally transverse edges;
first and second upright side surfaces extending from said transverse edges;
a generally arcuate surface extending between said first and second upright side surfaces and said first and second longitudinally extending edges.
5 . The device of claim 4 , wherein said body member further comprises a generally centrally located longitudinal axis extending therethrough and wherein said generally rectangular base surface is spaced radially from said longitudinal axis.
6 . The device of claim 1 , wherein said contrast agent is metallic.
7 . The device of claim 1 , wherein said targeting region is a liquid contrast agent.
8 . The device of claim 1 , wherein said body member is solid.
9 . The device of claim 1 , wherein said body member is a polymeric material.
10 . The device of claim 1 , wherein said targeting region is integrally formed with said body member.
11 . The device of claim 10 , wherein said targeting region is integrally molded into said body member.
12 . A medical targeting device, comprising:
an elongated body member extending between a distal end and a proximal end;
a laterally extending and defined chamber positioned adjacent the distal end and extending inwardly therefrom a predetermined distance; and
a contrast agent positioned within said chamber.
13 . The medical targeting device of claim 12 , wherein said chamber is closed off at said distal end by a distal end cap.
14 . The medical targeting device of claim 13 , wherein said distal end cap is secured to said distal end so as to seal said chamber.
15 . The medical targeting device of claim 13 , wherein said distal end cap further includes a mounting portion that is at least partially received within said chamber.
16 . The medical targeting device of claim 12 , wherein said body member is a generally solid member.
17 . The medical targeting device of claim 12 , wherein said contrast agent is molded into said chamber.
18 . A medical targeting device, comprising:
A elongated body member extending between a first end and a second end; and
a targeting region comprised of a contrast agent integrally formed with at least a portion of the targeting device, adjacent a distal end of the targeting device and extending inwardly therefrom a predetermined distance.
19 . The medical targeting device of claim 18 , wherein the elongated body member is solid and the targeting region is integrally formed in the second end of elongated body member so as to form a unitary member.
20 . The medical targeting device of claim 18 , further comprising a distal end section, wherein the targeting region is integrally formed with the distal end section and wherein the distal end section operatively connects to the first end of the elongated body member.
