The arrangement also controls the ease of lateral movement of the catheter in relationship to the elastomeric tube. The arrangement includes a substantially rigid telescoping tube for supporting the elastomeric tube therewithin. The rigid telescoping tube further includes an inner tube having a pin disposed on the outer circumference thereof; and an outer tube having an opening therein forming a slot, and a plurality of substantially equally spaced stops; a first clamping arrangement for fixing one end of the elastomeric tube to the end of the outer tube furthest from the inner tube; and, a second clamping arrangement for fixing the other end of the elastomeric tube to the end of the inner tube furthest from the outer tube.
