Abstract
A catheter includes an elongated tubular member having a lumen extending through the elongated tubular member. The elongated tubular member also has an outer surface, a distal end and at least one opening. The opening extends between the inner and outer surfaces, provides communication between the outer surface and the lumen and includes at least two straight edges extending parallel to the lumen of the tubular member.
Claims15
A catheter comprising:
- an elongated tubular member having a lumen extending through the elongated tubular member, the elongated tubular member further comprising an outer surface, a distal end, and at least one opening providing communication between the outer surface and the lumen and having at least two substantially straight edges extending parallel to the lumen.
A catheter comprising:
- an elongated tubular member having a lumen extending through the elongated tubular member, the elongated tubular member further comprising an outer surface, a distal end, a curved portion and an opening means in the curved portion providing communication between the outer surface and the lumen.
A method for manufacturing a catheter with at least one distal side opening comprising the steps of:
- creating a straight elongated tubular member having a distal end and a proximal end;
- punching into the distal end of the tubular member at least one opening having two straight edges extending parallel to a lumen of the tubular member;
- and
- curving the distal end of the tubular member to create an interior curved surface and an exterior curved surface and to position the opening in the interior curved surface.
