Abstract
Improved flow indwelling urinary catheters are disclosed in which inflow openings at a distal end of a catheter are distally biased and in proximity to a distal end of a catheter balloon resulting in greater urine outflow volume and velocity, greater urine emptying volume from the bladder and patent urine outflow as the catheter is withdrawn from the bladder.
Claims26
An indwelling urinary catheter having a catheter body, a balloon, a balloon inflation lumen, a common drainage lumen, and at least two diametrically opposed urine inflow openings at a distal end of the catheter body each of the urine inflow openings in fluid flow communication with the common drainage lumen, wherein the urine inflow openings have a distally facing bias with an opening orientation that is angularly displaced with an angle α between about 15 degrees to about 75 degrees relative to a longitudinal axis of the catheter body, wherein the catheter body further includes a substantially frustoconical distal tip and the at least two diametrically opposed urine inflow openings pass into the substantially frustoconical distal tip forming a substantially Y-shaped opening in fluid flow communication with the drainage lumen and are configured to convey urine flow into both of the at least two diametrically opposed urine inflow openings simultaneously and remain open to urine inflow when the balloon is in both its inflated and deflated states and when the distal tip is positioned in the urinary bladder or urethra.

An indwelling urinary catheter, comprising a catheter body having a substantially conical distal tip, an inflatable balloon in proximity to the substantially conical distal tip, a balloon inflation lumen, a balloon inflation connector, a drainage lumen, a drainage port, and at least two urine inflow openings passing through lateral wall surfaces of the distal tip, wherein each of the at least two urine inflow openings have an angle between about 20 to about 45° relative to a longitudinal axis of the catheter body.
An indwelling urinary catheter having a catheter body, a balloon, a balloon inflation lumen, a drainage lumen, and opposing urine inflow openings at a distal end of the catheter body in fluid flow communication with the drainage lumen, comprising, at least one fluid conduit passing between the opposing urine inflow openings and the drainage lumen, the fluid conduit having an angle α between about 15 degrees to about 75 degrees relative to a longitudinal axis of the catheter body such that the at least one fluid conduit and the drainage lumen for a substantially Y-shaped fluid conduit, wherein the catheter body further includes a substantially frustoconical distal tip and the opposing urine inflow openings pass laterally through the wall surfaces and are in fluid flow communication with the fluid conduit and the drainage lumen and are configured to convey urine flow into both of the opposing urine inflow openings simultaneously and the opposing urine inflow openings remain open to urine inflow when the balloon is in both its inflated and deflated states and when the frustoconical distal tip is in the urinary bladder or urethra.
