Abstract

A ureteral drainage stent is designed to be placed in a patient's ureter and extend into a patient's bladder. An elongated tubular segment includes a distal region for placement in the renal cavity, and a proximal region for placement in a urinary bladder. A central lumen connects at least one opening in the distal region to at least one opening in the proximal region. The elongated segment is constructed such that the wall surrounding the lumen is thinner in the proximal region than in the distal region. The thin-walled portion of the elongated segment extends along at least part of the ureter, across the ureteral vesicle junction, and from there into the bladder.

Claims

AMENDED CLAIMS[received by the International Bureau on 03 December 2002 (03.12.02); original claims 1, 15 and 37 amended; remaining claims unchanged (4 pages)]
1. A medical device for assisting the drainage of fluid from a body cavity, comprising: an elongated segment extending from a distal region through a transition zone to a proximal region comprising a pliable wall, said segment having a substantially constant outer diameter and an inner wall defining a lumen having an inner diameter in the proximal region that is greater than the inner diameter in the distal region.
2. The medical device of claim 1, wherein said device comprises a stent.
3. The medical device of claim 1, wherein said device comprises a ureteral stent.

5. The medical device of claim 1, wherein said transition zone comprises varying inner diameters between said proximal and distal regions.
6. The medical device of claim 1, further comprising at least one member extending through at least some of said lumen to said proximal region.
7. The medical device of claim 6, wherein said member comprises a flexible material.
8. The medical device of claim 6, wherein said member comprises a thread.
9. The medical device of claim 6, wherein said member is secured to the inner wall.
10. The medical device of claim 6, wherein said member comprises a substantially noncompressible material.
11. The medical device of claim 6, wherein said member includes a loop.
12. The medical device of claim 1, wherein said elongated segment further comprises a retention structure in the distal region.
13. The medical device of claim 1, wherein said elongated segment further comprises a kink resistant retention structure in the distal region.
14. The medical device of claim 1, wherein said elongated segment further comprises a coil in the distal region.
15. The medical device of claim 1 , wherein said proximal region is flexible.
16. A medical device for assisting the drainage of fluid from a body cavity, comprising: an elongated segment extending from a distal region through a transition zone to a proximal region, said segment having a substantially constant outer diameter and an inner wall defining a lumen having an inner diameter in the proximal region that is greater than the inner diameter in the distal region; and a second segment comprising an exterior wall contacting at least a portion of the inner wall of said elongated segment, and further comprising an inner wall defining a lumen coaxial with said lumen of said elongated segment.
