Drainage catheter system

A drainage catheter system which comprises:

• a) an elongate catheter body dimensioned for insertion into a patient's urethra, said elongate catheter body having an interior lumen extending therethrough defined by an interior surface and having an exterior surface;
• b) an elongate tubular sheath operatively associated with said catheter body and having opposed first and second ends, the first and second ends of said sheath being positioned adjacent the exterior surface of said catheter body and said sheath being supported by said catheter body to facilitate progressive deployment of the elongate tubular sheath from within the interior lumen of the catheter body during insertion of the catheter body into a patient's urethra;
• and
• c) a layer of lubricant sealingly disposed between said sheath and said catheter body along the interior and exterior surfaces thereof to reduce frictional resistance between said sheath and said catheter body.

• b) an elongate tubular sheath operatively associated with said catheter body and having opposed first and second ends, the first and second ends of said sheath supported adjacent the exterior surface of said catheter body;
• c) a layer of lubricant sealingly disposed between said sheath and said catheter body along the interior and exterior surfaces thereof to reduce frictional resistance between said sheath and said catheter body;
• and
• further including a grip member positioned adjacent said exterior surface of said catheter body, said grip member being movable relative to said catheter body.

A drainage catheter system which comprises:

• a) an elongate catheter body having an interior lumen extending therethrough defined by an interior surface and having an exterior surface;
• b) an elongate tubular sheath operatively associated with said catheter body and having opposed first and second ends, the first and second ends of said sheath supported adjacent the exterior surface of said catheter body;
• and
• c) a layer of lubricant sealingly disposed between said sheath and said catheter body along the interior and exterior surfaces thereof to reduce frictional resistance between said sheath and said catheter body,
• wherein said tubular sheath includes a multiplicity of bumps to reduce slippage between said tubular sheath and a patient's urethra.

• b) an elongate tubular sheath operatively associated with said catheter body and having opposed first and second ends, the first and second ends of said sheath supported adjacent the exterior surface of said catheter body;
• c) a layer of lubricant sealingly disposed between said sheath and said catheter body along the interior and exterior surfaces thereof to reduce frictional resistance between said sheath and said catheter body;
• and
• further including means for inflating said tubular sheath.

A closed system collection bag comprising:

• a fluid entry portion defining a fluid conduit, the conduit having a one-way fluid valve in line to prevent back flow of fluid and a gas separation chamber for venting gas to the atmosphere, said fluid entry portion further including at least one one-way gas valve for preventing entry of ambient air into the collection bag;
• a main liquid reservoir in fluid communication with the fluid entry portion for receiving and storing liquid therein;
• and
• a sealed drainage member in fluid communication with the main liquid reservoir for permitting drainage of the main liquid reservoir.

A collection bag saddle comprising:

• a main body portion;
• a plurality of mounting pads attached to the main body portion, the mounting pads having adhesive backing thereon for adherence to a patient's skin;
• and
• collection bag mounting structure supported by the main body portion, the collection bag mounting structure being configured to releasably mount a collection bag thereon.
