Abstract
Catheter to be used in the skull area consisting of an elongated elastic tube having a closed distal end and having a connecting part arranged at the rear end. The tube comprises an opening at a predetermined distance from said distal end, the dimensions of said opening being sufficient for inserting an elongated manipulating needle into the tube such that the distal point of said needle contacts the closed distal top of the catheter. Furthermore the tube may comprise a closure element which is clamped around the tube and can be shifted along the tube between a first position in which said opening is covered by said closure element and at least one further position in which the opening is not obstructed.
Claims10
Catheter to be used in the skull area consisting of an elongated tube having a closed distal end and having a connecting part arranged at a rear end, said catheter characterized in that the tube has an opening at a predetermined distance from said distal end, said opening having dimensions sufficient for allowing insertion of an elongated manipulating needle into the tube such that a distal point of said needle contacts the closed distal end of the catheter, said needle having a desired length and being used to locate said catheter in said skull, said needle being removed through said opening after said catheter is located, and said predetermined distance being larger than a maximum length of the catheter introduced into the skull and shorter than the length of the manipulating needle.
