Dual lumen catheter with contrastradiography sections to identify the lumens

摘要

A catheter has an outer peripheral portion (15) in the form of a tube and an internal, wall (16, 26) within the tube forming a plurality of lumens (11a, 11b, 21a, 21b). Axially extending linear contrastradiography sections (17a, 17b, 27a, 27b) of radiopaque material are formed at a plurality of intersection points between the outer peripheral section and the wall, the peripheral extent (a, b) of the respective contrastradiography sections being different.

主权项

1. A catheter comprising:
a catheter main body having a first and second end, the catheter main body including an outer peripheral section and an internal wall intersecting the outer peripheral section to define first and second lumens extending along a longitudinal axis defined by the catheter main body; and first and second contrastradiography sections disposed at least within the outer peripheral section, at the intersection of the outer peripheral section and the internal wall, and the first and second contrastradiography sections defining respective first and second different peripheral extents.
