Ureteral and bladder catheters and methods of inducing negative pressure to increase renal perfusion
First Claim
1. A ureteral catheter, comprising:
- a drainage lumen comprising a proximal portion and a distal portion configured to be positioned in a patient'"'"'s kidney, renal pelvis and/or in the ureter adjacent to the renal pelvis, the distal portion comprising a coiled retention portion, the coiled retention portion comprising;
at least a first coil having a first diameter;
at least a second coil having a second diameter, the first diameter being less than the second diameter, the second coil being closer to an end of the distal portion of the drainage lumen than the first coil; and
one or more perforations on a sidewall of the coiled retention portion of the distal portion of the drainage lumen for permitting fluid flow into the drainage lumen,wherein the proximal portion of the drainage lumen is essentially free of or free of perforations.

Abstract
Ureteral catheters and assemblies are provided including: a drainage lumen including a proximal portion configured to be positioned in at least a portion of a patient'"'"'s urethra and a distal portion configured to be positioned in a patient'"'"'s ureter and/or kidney, the distal portion including a coiled retention portion including at least a first coil having a first diameter and a second coil having a second diameter, the first diameter being less than the second diameter; or wherein the retention portion extends radially outwardly from a portion of the distal end of the drainage lumen portion, the retention portion including a proximal end having a first diameter, a distal end having a second diameter, and a wall and/or surface extending therebetween, the retention portion having a second diameter is greater than the first diameter when deployed; or wherein the retention portion includes a plurality of drainage tubes.
