Abstract
An introducer sheath (30) having a short distal tip section (34,40) that is highly radiopaque. The distal tip section may be of FEP with 20% to 75% by weight tungsten particulate filler, and may be initially a separate member (40) and bonded to the sheath shaft distal end (32).
Claims14
An introducer sheath comprising:
- a shaft extending from a proximal end portion to a distal end portion;
- and
- a distal tip section at said distal end portion of said shaft,
- said distal tip section comprising a polymeric material containing over 20% and up to about 75% by weight of radiopaque material, and
- said shaft being distinctly less radiopaque than said distal tip section.
