Abstract

A notched catheter has a lumen and a notched outer surface intersecting the lumen with a filament-containing layer adjacent to the outer surface. A part of the filament-containing layer is capturable between the notched surface portion and an elongate element extendable through the lumen.

Claims

1. A notched catheter comprising:

a catheter body having an outer surface and a longitudinally extending lumen;

the outer surface having a main surface portion and a notched surface portion, the notched surface portion extending from the main surface portion to intersect the lumen; and

a filament-containing layer adjacent to the main surface portion and the notched surface portion, whereby a portion of the filament-containing layer is capturable between the notched surface portion and an elongate element extendable through the lumen.

2. The notched catheter according to claim 2 wherein catheter body comprises a second, main lumen and the filament-containing layer comprises a braided material impregnated with a polymer.
