Abstract

The present invention relates to a rapid exchange or single operator exchange catheter device comprising at least one elongated tubular member having an inner surface and an outer surface, a proximal and a distal end, and having an opening located between the proximal and the distal end. The inner surface of the elongated tubular member defines a guide member lumen and is at least occasionally subjected to contact with at least one guide member. The guide member lumen, including the opening or port for receiving the guide member, are filled with the lubricious material in accordance with the present invention. This method of filling the lumen eliminates the need for flushing the catheter device before and/or during surgical procedures to remove air and contaminants and provides a lubricant for easy maneuvering of the catheter over the guide member.

Claims

1. A non-flush catheter device having a storage state and a use state, said device comprising at least one elongated tubular member having an inner surface and an outer surface, a proximal and a distal end, and wherein said inner surface of said elongated tubular member defines a guide member lumen and is at least occasionally subjected to contact with at least one guide member, said guide member lumen filled with a lubricious material throughout the storage state and the use state.

2. The catheter device of claim 1 wherein said device is a single operator exchange catheter device.

3. The catheter device of claim 2 wherein said elongated tubular member further has an opening located between said proximal end and distal end for receiving a guide member.

4. The device of claim 1 wherein said elongated tubular member is a catheter shaft and further comprises an inner shaft having an inlet port, said inlet port for receiving a guide member therein.

5. The device of claim 1 wherein said elongated tubular member comprises a thermoplastic polymeric material.

6. The device of claim 1 wherein said guide member comprises at least one metal or metal alloy.

7. The device of claim 1 wherein said lubricious material is selected from hydrophilic materials, hydrophobic materials, and mixtures thereof.

8. The device of claim 7 wherein said lubricious material is selected from polyalkylene glycols;

alkoxy polyalkylene glycols;

poly(saccharide);

poly(vinylpyrrolidone);

poly(vinyl alcohol);

poly(acrylic acid);

poly(acrylamide);

poly(maleic anhydride);

copolymers thereof and mixtures thereof.

9. The catheter device of claim 1 wherein said inner surface of said elongated tubular member defining said guide member lumen is pretreated with a reactive primer composition.

10. The catheter assembly of claim 9 wherein said reactive primer composition comprises at least one crosslinkable silicone compound.

11. The catheter device of claim 10 wherein said silicone compound comprises amino groups.

13. The catheter device of claim 9 wherein said lubricious material comprises at least one hydrophilic compound which is an ethoxylated castor oil or a polyoxypropylene/polyoxyethylene copolymer.

14. The catheter device of claim 1 wherein said inner surface of said elongated tubular member defining said guide member lumen is pretreated with plasma.

15. The device of claim 1 wherein said device is a stent deployment device.

16. The device of claim 1 wherein said device is a dilatation catheter comprising an inflatable medical balloon.

17. The non-flush catheter device of claim 1 wherein during the use state, a guide wire is inserted through said guide wire lumen displacing some of said lubricious material.

12. The catheter device of 10 wherein said silicone is a liquid amino polydimethylsiloxane.

18. A single operator exchange or rapid exchange nonflush catheter device having a storage state and a use state, said device having a proximal end and a distal end comprising a shaft having an inner surface and an outer surface, and proximal and distal ends, the shaft open at said proximal and distal ends, and carried in said shaft is a guide wire lumen defined by said inner surface of said shaft, said shaft having a guide wire port for receiving a guide wire located between said proximal and distal ends of said device, and filling said guide wire lumen is a lubricious material, said lumen filled with said lubricious material throughout the storage state and the use state.

19. A single operator exchange or rapid exchange non-flush catheter device having a storage state and a use state, said device comprising a sheath wherein a guide member is adapted to be inserted into a patient'"'"'s vasculature so that a distal portion of the guide member is within the patient and a proximal portion thereof remains outside the patient, the sheath comprising an elongated tubular member having an inner surface defining a single longitudinally extending lumen sized to slidably receive a guide member therein, the tubular member having a distal insertion opening in communication with the lumen adjacent its distal end, a proximal insertion opening in communication with the lumen adjacent its proximal end, and having, a side hole port in communication with the lumen for receiving said guide member, and filling said lumen is a lubricant material, said lumen filled with said lubricant material throughout the storage state and the use state.

20. A non-flush catheter delivery device comprising at least one elongated tubular member having an inner surface and an outer surface, a proximal and a distal end, said inner surface of said elongated tubular member defines a guide member lumen and is at least occasionally subjected to contact with at least one guide member, and wherein said non-flush catheter delivery device is stored with said guide member lumen filled with a non-flowing lubricious material.
