Abstract

A urinary catheter assembly includes a urinary catheter having a proximal part with an insertion tip, a distal part and a tubular shaft extending between the insertion tip and the distal part. A package having at least a first compartment with an opening is provided to enclose the proximal part and at least a part of the tubular shaft therein in a curved or curled state during storage. A protective sleeve arrangement is arranged around the distal part of the urinary catheter, and a distal end of the protective sleeve arrangement is connected to the urinary catheter, at or in the vicinity of a distal end of the catheter. The protective sleeve arrangement includes at least two sleeves that are telescopically displaceable in relation to each other, and the protective sleeve arrangement is transformable between a retracted position and an extended position.
