Patent ID: 8708999

Claim:
A urinary catheter and enclosure system, the system comprising: a urinary catheter having a distal end configured for insertion into a urethra, a main catheter portion, and a conical proximal portion that ends in a proximal end having a diameter that is wider than the main catheter portion and the distal end; a tubular sheath slidably disposed around part of the catheter at or near the distal end; an enclosure for enclosing at least part of the urinary catheter, the enclosure comprising: a bottom member; a top member disposed over the bottom member so as to rotate relative to the bottom member about an axis of rotation; a first hole located in a first location on the enclosure and configured to allow advancement of the catheter distal end therethrough; and a second hole located in a second location on the enclosure, separated from the first location, out of which the catheter proximal portion extends, the second hole having a diameter that is smaller than the diameter of the catheter proximal end, such that the proximal end is restricted from slipping through the second hole, wherein rotating one of the top member or the bottom member relative to the other member causes the catheter to wind into a spiral within the enclosure; and a lubricant disposed on the catheter, under the tubular sheath.
