PCT No. PCT/SE82/00124 Sec. 371 Date Dec. 13, 1982 Sec. 102(e) Date Dec. 13, 1982 PCT Filed Apr. 16, 1982 PCT Pub. No. WO82/03557 PCT Pub. Date Oct. 28, 1982.The present invention discloses a urinary catheter with a retention member in the form of an expandable balloon. The expandable balloon is arranged below the inlet opening and so designed that in its inflated condition a portion projects forward past the catheter tip at some distance from the inlet opening. The unique design of the catheter prevents contact between the wall of the urinary bladder and the catheter tip thereby avoiding infection and traumatization of the tissues. |
