ABSTRACT:
The present invention provides a variable diameter catheter which is folded in a longitudinal manner in order to reduce the diameter for convenient and less traumatic insertion into a body orifice. The fold in the catheter is maintained by a slidably removable external sheath which aids in insertion of the catheter and in dispersion of an anti-infective medication. Once the catheter is placed in the body orifice, the external sheath is removed. The present invention is also directed to the external sheath.
