Abstract

A catheter fabricated of unitary incineratable polymeric material, including a removable solid pusher rod closely mated to the interior of the cannula, engagable with the front tapered end thereof to strengthen and stiffen the cannula during insertion into the body.

Claims

1. A hollow catheter for delivering or receiving fluid from a vein, comprising:

a hollow, cylindrical, elongated, thin, unitary incineratable polymeric main body portion including an interior wall having a first end for piercing, penetrating and temporarily indwelling in a vein, said first end including a solid piercing point and a plurality of openings extending from adjacent the point to the hollow interior and a second end adapted to mate with a tube for delivery or receipt of the fluid; and

a cylindrical, rigid pusher rod closely mated to the interior wall of said body portion, said pusher rod inserted within said main body portion during the placement thereof within the vein and removed prior to the attachment of a tube.

2. A catheter having at least one non-axial opening.

3. A hollow catheter fabricated of a polymeric material capable of being incinerated, comprising:

an elongated, hollow unitary main body portion with an inner wall, including a pointed solid, uniformly tapered first end including openings extending from the tapered surface to the hollow interior and a second end adapted to receive the end of a mating tube; and

an insertable cylindrical pusher rod closely mated to the inner wall of the catheter and used for inserting the first end of the catheter into a receiving vein and then removed.
