Abstract

A medical device can be used to drain fluids from the body during a medical procedure that requires the insertion of a medical instrument into an anatomical lumen or cavity. The device generally allows the simultaneous introduction of the medical instrument into the body and drainage of fluid out of the body during a medical procedure.

Claims (27)

1. A medical device comprising:

a tubular access member for insertion into a urinary system comprising an open insertion end, an open proximal end, and a lumen, wherein the tubular access member is adapted to allow access for at least one medical instrument through the lumen, the tubular access member being sized to extend from a location in a kidney of a patient to a location beyond a urethra of the patient; and

a tubular drainage member comprising a first end portion, a drainage end portion, and a lumen for draining fluid from the urinary system, the first end portion of the tubular drainage member includes a curved portion, the open insertion end of the tubular access member being disposed apart from the first end portion of the tubular drainage member, the open proximal end of the tubular access member being disposed apart from the drainage end portion of the tubular drainage member, the tubular drainage member being sized to extend from a location in a bladder of the patient to a location beyond the urethra of the patient,

wherein a portion of the tubular access member is coupled to a portion of the tubular drainage member.

2. The medical device of claim 1 , wherein the curved portion of the tubular drainage member forms a coil.

3. The medical device of claim 1 , wherein at least one of the tubular access member and the tubular drainage member includes a plurality of apertures for migration of fluid.

4. The medical device of claim 1 , wherein the tubular access member tapers inward at the insertion end.

5. The medical device of claim 1 , wherein the tubular drainage member is sized to extend from a location in the urinary system to a location beyond the urethra.

6. The medical device of claim 1 , wherein the tubular drainage member includes a valve.

7. The medical device of claim 1 , wherein the tubular access member includes medial portion disposed between the open insertion end and the open proximal end, the tubular drainage member includes a middle portion disposed between the first end portion and the drainage end portion, the medial portion of the tubular access member being coupled to the middle portion of the tubular drainage member.

8. The medical device of claim 1 , wherein the tubular drainage member includes a securement member disposed between a middle portion of the tubular drainage member and the first end portion of the tubular drainage member.

9. The medical device of claim 1 , wherein the tubular access member includes medial portion disposed between the open insertion end and the open proximal end, the tubular drainage member includes a middle portion disposed between the first end portion and the drainage end portion, the medial portion of the tubular access member being coupled to the middle portion of the tubular drainage member, the tubular drainage member includes a securement member disposed between the middle portion of the tubular drainage member and the first end portion of the tubular drainage member.

10. The medical device of claim 1 , wherein the tubular drainage member is disposed outside the lumen of the tubular access member.

11. A medical device comprising:

a tubular access member for insertion into a urinary system having an open insertion end, an open proximal end, a medial portion disposed between the open insertion end and the open proximal end, and a lumen, wherein the tubular access member is adapted to allow access for at least one medical instrument through the lumen, the tubular access member being sized to extend from a location in a kidney of a patient to a location beyond a urethra of the patient; and

a tubular drainage member having a first end portion, a drainage end portion, a middle portion disposed between the first end portion and the drainage end portion, and a lumen for draining fluid from the urinary system, the middle portion of the tubular drainage member being coupled to the medial portion of the tubular access member, the open insertion end of the tubular access member being disposed apart from the first end portion of the tubular drainage member, the open proximal end of the tubular access member being disposed apart from the drainage end portion of the tubular drainage member, the tubular drainage member being sized to extend from a location in a bladder of the patient to a location beyond the urethra of the patient.

12. The medical device of claim 11 , wherein the tubular drainage member includes a portion that forms a coil.

13. The medical device of claim 11 , wherein at least one of the tubular access member and the tubular drainage member includes a plurality of apertures for migration of fluid.

14. The medical device of claim 11 , wherein the tubular access member tapers inward at the insertion end.

15. The medical device of claim 11 , wherein the tubular drainage member is sized to extend from a location in the urinary system to a location beyond the urethra.

16. The medical device of claim 11 , wherein the tubular drainage member includes a valve.

17. The medical device of claim 11 , wherein the tubular drainage member includes a securement member disposed between the middle portion of the tubular drainage member and the first end portion of the tubular drainage member.

18. A medical device comprising:

a tubular access member for insertion into a urinary system having an open insertion end, an open proximal end, a medial portion disposed between the open insertion end and the open proximal end, and a lumen, wherein the tubular access member is adapted to allow access for at least one medical instrument through the lumen;

a tubular drainage member having a first end portion, a drainage end portion, a middle portion disposed between the first end portion and the drainage end portion, and a lumen for draining fluid from the urinary system, the middle portion of the tubular drainage member being coupled to the medial portion of the tubular access member, the open insertion end of the tubular access member being disposed apart from the first end portion of the tubular drainage member, the open proximal end of the tubular access member being disposed apart from the drainage end portion of the tubular drainage member; and

a securement member coupled to the tubular drainage member at a location on the tubular drainage member, the location on the tubular drainage member being disposed a distance from the tubular access member.

19. The medical device of claim 18 , wherein an outer surface of the securement member is disposed between the tubular access member and the tubular drainage member.
