Drainage catheter and method for the manufacture thereof.

摘要

Drainage catheter (1) such as a nephrostomy catheter and method for the manufacture thereof, comprising the extrusion from flexible plastic of a tubular basic body (2) with a central channel (8), the attachment to one end of said basic body of a coupling element (3), the deformation of the opposite end part (4) into a curved form and the arrangement in the curved end part of a number of side-openings (5) connecting said central channel to the outside. Said basic body is extruded such that said central channel comes to lie eccentrically in said basic body. During the plastic deformation of said end part said basic body is supported for free rotation along its lengthwise axis and the arranging of the side openings is carried out after said end part has been plastically deformed into the curved shape.
