Urinary catheter and bladder irrigation system

A soft tip suitable for being integrally and permanently mounted at the distal end of a catheter having at least two lumina, said tip comprising:

• an exterior roof and an interior ceiling, said roof being rounded for ease of insertion into a body cavity;
• delivery means defining an aperture centrally disposed in said tip, said aperture being fluidly connected with the second lumen for delivery of solution into the body cavity;
• drainage means defining at least two drainage ports laterally disposed in said tip, said drainage ports being fluidly connected with the first lumen for removal of waste materials from the body cavity;
• oriface means within said tip defining a passage for entry of said solution from said second lumen into said first lumen;
• and
• deflection means within said tip to deflect said solution downward and past said drainage ports such that the downward flow creates suction to assist removal of the waste materials from the body cavity, said deflection means being a concavity in the ceiling.

A catheter adaptable for insertion into a body cavity and capable of delivering an irrigating solution thereto and of providing a mild suction to assist in the removal of waste materials such as blood clots, bacteria, fluids and tissue debris therefrom, said catheter comprising:

• a substantially flexible tube means having a proximal end and a distal end;
• first and second lumina extending substantially the length of said tube, said first lumen for drainage of the waste materials from the body cavity and said second lumen for delivery of the irrigating solution to the body cavity;
• tip means integral with the distal end of said tube;
• delivery means defining an aperture centrally disposed in said tip, said aperture being fluidly connected to said second lumen for administering the irrigating solution into the body cavity;
• drainage means defining at least two drainage ports laterally disposed in said tip, said drainage ports being fluidly connected to said first lumen for removal of the waste materials from the body cavity;
• at least two clot breaking members disposed opposite and below said drainage ports;
• oriface means within said tip defining a passage for entry of said irrigating solution from said second lumen into said first lumen such that the irrigating solution cleanses the length of the first lumen;
• deflection means within said tip to deflect said irrigating solution downward and past said drainage ports such that the downward flow creates the suction to assist removal of the waste materials from the body cavity;
• and
• separate external means at the proximal end of the tube for communication with said first and second lumina.
