Elongated medical catheter including marker band
An elongated medical catheter includes a marker band with sidebands. The elongated medical catheter and the marker band have a radiopacity being different from the radiopacity of the sidebands.
1. An apparatus, comprising:
an elongated medical catheter including a marker band with a first sideband and a second sideband, said first and second sidebands are directly attached to opposite sides of the marker band; and
wherein a catheter radiopacity of the elongated medical catheter and a marker band radiopacity of the marker band are different from a radiopacity of the first sideband and the second sideband, the radiopacity of the first sideband being less than the catheter radiopacity and the radiopacity of the second sideband being less than the marker band radiopacity.
2. The apparatus of claim 1 , wherein:
the elongated medical catheter defines a catheter lumen extending through the sidebands and the marker band.
3. The apparatus of claim 1 , wherein:
the catheter radiopacity decreases near the marker band.
4. The apparatus of claim 3 , wherein:
a proportion of radiopaque materials in the elongated medical catheter near the marker band is reduced.
5. The apparatus of claim 3 , wherein:
radiopaque materials are omitted in the elongated medical catheter near the marker band.
6. An apparatus, comprising:
an elongated medical catheter having a catheter distal portion and a catheter proximal portion, the catheter having a catheter radiopacity;
a marker band having a first end portion and a second end portion and being positioned between the catheter distal portion and the catheter proximal portion, the marker band having a marker band radiopacity;
a first sideband having a first sideband radiopacity and being directly bonded to the first end portion of the marker band; a second sideband having a second sideband radiopacity and being directly boned to the second end portion of the marker band;
wherein the first sideband radiopacity is less than the catheter radiopacity and the second sideband radiopacity is less than the marker band radiopacity, and wherein the catheter radiopacity decreases near the marker band.
7. The apparatus of claim 6 , wherein:
the elongated medical catheter defines a catheter lumen extending through the first sideband, the second sideband and the marker band.
8. The apparatus of claim 6 , wherein:
the catheter radiopacity of the elongated medical catheter is less than the radiopacity of the marker band.
9. The apparatus of claim 6 , wherein:
a proportion of radiopaque materials in the elongated medical catheter near the marker band is reduced.
10. The apparatus of claim 6 , wherein:
radiopaque materials are omitted in the elongated medical catheter near the marker band.
11. The apparatus of claim 6 , wherein:
the elongated medical catheter includes a first catheter section and a second catheter section; and
the first catheter section is positioned proximate to the first sideband; and
the second catheter section is positioned proximate to the second sideband.
12. The apparatus of claim 11 , wherein:
the elongated medical catheter defines a catheter lumen extending through the first sideband, the second sideband, the marker band, the first catheter section and the second catheter section.
13. A method of using an elongated medical catheter, the method including:
providing the elongated medical catheter having a marker band and first and second sidebands, said first and second sidebands are directly attached to opposite sides of the marker band, each of the elongated medical catheter and the marker band having a radiopacity being different from a radiopacity of the first sideband and the second sideband, the radiopacity of the first sideband being less than the radiopacity of the elongated medical catheter and the radiopacity of the second sideband being less than the radiopacity of the marker band, and the radiopacity of the elongated medical catheter decreasing near the marker band; and operably coupling the elongated medical catheter with a compatible medical-imaging system.
14. The method of claim 13 , wherein:
a proportion of radiopaque materials in the elongated medical catheter near the marker band is reduced.
15. The method of claim 13 , wherein:
radiopaque materials are omitted in the elongated medical catheter near the marker band.
