Packaging including a coiled and optionally prelubricated catheter, its distal end insertable into the urethra, a slidable hygienic sheath, a proximal catheter end for voiding urine from the distal end through the assembly to the proximal end. Mutually rotatable elements providing for withdrawal of the catheter from its coiled state to an extended state, and retraction of the catheter back to its coiled state. Methods of extending the catheter, inserting it into the urethra, and voiding urine through the catheter, without requiring complete removal from the catheter packaging. A kit including automatic extrusion of the catheter's distal end upon package opening, and a water pouch for hydrophilic lubrication, and sanitary wipes for reducing the likelihood of infection. A catheter within a flexible and optionally coiled tube, a slidable hygienic sheath covering a catheter's distal end that can move along the length of the catheter during insertion.

1. 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; anda 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; anda lubricant disposed on the catheter, under the tubular sheath. 2. A system as in claim 1, wherein the lubricant comprises a hydrophilic lubricant. 3. A system as in claim 1, further comprising a sealed package enclosing the catheter, the sheath and the enclosure. 4. A system as in claim 3, wherein the sealed package comprises a tearable pouch. 5. A system as in claim 1, wherein the enclosure, the catheter and the sheath are configured to allow a user to advance the catheter into a urethra and void urine through the catheter by touching only the sheath and the enclosure and without touching the catheter. 6. A system as in claim 1, wherein the proximal end of the catheter remains anchored outside of the enclosure throughout use of the system, such that urine passes into the distal end of the catheter, through the catheter, and out the proximal end of the catheter, while the catheter is attached to the enclosure. 7. A system as in claim 6, further comprising a urine receiving bag removably attached to the proximal end of the catheter. 8. An assembly as in claim 6, wherein the conical proximal portion of the catheter has a fixed shape that does not change. 9. A system as in claim 1, wherein the sheath comprises: a first, removable portion located at the catheter's distal end; anda second, slidable portion, configured to be slidably moved along the catheter. 10. A system as in claim 1, wherein the top member and the bottom member coupled together form a donut shape having an inner core wall and an external restraining wall. 11. A system as in claim 10, wherein the first hole is located on the external restraining wall and the second hole is located on the inner core wall. 12. A system as in claim 1, further comprising a flexible tube disposed around a majority of the catheter, wherein the flexible tube comprises a distal end, a proximal end, and a portion disposed substantially in a coil. 13. A system as in claim 1, further comprising multiple surface members disposed on at least one of the top member or the bottom member, wherein the surface members are configured to facilitate rotation of one the top member and the bottom member relative to the other. 14. A system as in claim 13, wherein the multiple members are selected from the group consisting of bumps, handles and ridges.
