The present disclosure relates to a packaged urinary catheter assembly and method of using the packaged urinary catheter assembly. The catheter assembly includes a conduit having a proximal end and a distal end. The distal end includes at least one aperture for receiving fluid from a patient. The conduit is contained within a sleeve having a length, a width, and a size configured to receive the catheter. According to one embodiment, the conduit and the sleeve may be arranged in a helical coil. The outer surface of the conduit may have a lubricious and/or an antimicrobial coating.

1. A method of catheterization, comprising: obtaining a catheter assembly, the catheter assembly including: a conduit having a proximal end and a distal end, the distal end including an aperture for receiving fluid from a patient; anda sleeve surrounding a length of the conduit, wherein the conduit and the sleeve are arranged in a helical coil configuration, and wherein the helical coil configuration is maintained by portions of the sleeve being releasably fixed together along at least a portion of the helical coil configuration;releasing the conduit and the sleeve from the helical coil configuration such that the portions of the sleeve are no longer fixed together;inserting the distal end of the conduit into a patient. 2. The method according to claim 1, wherein a first cap seals a proximal end of the sleeve, and a second cap seals a distal end of the sleeve, and wherein the second cap is removed before inserting the distal end of the conduit into the patient. 3. The method according to claim 2, wherein at least one of the first and second caps comprises a gripping feature, and wherein releasing the conduit and the sleeve from the helical coil configuration includes grasping the gripping feature. 4. The method according to claim 3, wherein the gripping feature is sized and shaped to receive a finger therethrough. 5. The method according to claim 1, wherein the releasably fixed portions of the sleeve include a perforated section, and wherein releasing the conduit and the sleeve from the helical coil configuration includes tearing the perforated section. 6. The method according to claim 2, wherein releasing the conduit and the sleeve from the helical coil configuration is done by grasping the first and second caps, and urging the caps in substantially different directions. 7. The method according to claim 1, wherein a lubricating material is contained within the sleeve, and wherein the lubricating material lubricates the distal end of the conduit before inserting the distal end of the conduit into the patient. 8. The method according to claim 7, wherein the lubricating material is selected from the group consisting of water, a hydrogel, and a vapor. 9. The method according to claim 1, wherein at least a portion of an outer surface of the conduit is hydrophilic, and wherein inserting the distal end of the conduit into the patient includes inserting the hydrophilic portion into the patient. 10. The method according to claim 1, wherein the sleeve is constructed from two blanks of material that are initially joined at edges of the two blanks of material, and wherein releasing the conduit and the sleeve from the helical coil configuration includes separating the edges of the two blanks of material. 11. The method according to claim 1, wherein the sleeve is constructed from a foil material or a film. 12. A method of catheterization, comprising: obtaining a urinary catheter assembly, the urinary catheter assembly including: a synthetic polyisoprene conduit having a proximal end and a distal end, the distal end including at least one aperture for receiving urine from a bladder; anda sleeve surrounding a length of the conduit, wherein the conduit and the sleeve are arranged in a helical coil shape, and wherein the helical coil shape is maintained by portions of the sleeve being releasably fixed together along at least a portion of the helical coil shape;releasing the conduit and the sleeve from the helical coil shape such that the portions of the sleeve are no longer fixed together;inserting the distal end of the conduit into the bladder. 13. The method according to claim 12, wherein a first cap seals a proximal end of the sleeve, and a second cap seals a distal end of the sleeve, and wherein the second cap is removed before inserting the distal end of the conduit into the bladder. 14. The method according to claim 13, wherein at least one of the first and second caps comprises a gripping feature, and wherein releasing the conduit and the sleeve from the helical coil shape includes grasping the gripping feature. 15. The method according to claim 14, wherein the gripping feature is sized and shaped to receive a finger therethrough. 16. The method according to claim 14, wherein the first and second caps are disposed outside the sleeve. 17. The method according to claim 16, wherein releasing the conduit and the sleeve from the helical coil configuration is done by grasping the first and second caps, and urging the caps in substantially different directions. 18. The method according to claim 12, wherein a lubricating material is contained within the sleeve, and wherein the lubricating material lubricates the distal end of the conduit before inserting the distal end of the conduit into the bladder. 19. The method according to claim 18, wherein the lubricating material is selected from the group consisting of water, a hydrogel, a vapor, and combinations thereof. 20. The method according to claim 12, wherein at least a portion of an outer surface of the conduit is hydrophilic, and wherein inserting the distal end of the conduit into the bladder includes inserting the hydrophilic portion into the bladder.
