Abstract

A urinary catheter assembly (10) having a folded, compact configuration and a straight ready to use configuration, having an outer tube (30) and an inner catheter tube (12), the inner catheter tube comprising a bendable region (24), the inner catheter tube and the outer tube being movable relative to one another so that a bending element of the bendable region of the inner catheter tube is moved into the lumen of the outer tube, thereby straightening the inner catheter tube so as to place the urinary catheter assembly into a straight ready to use configuration.

First claim

What is claimed is:

1 . A urinary catheter product, comprising:
a urinary catheter assembly comprising:
outer tube having a lumen;
an inner catheter tube partially positioned within the lumen of the outer tube, the inner catheter tube including a bendable region having a bending element, the bendable region being at least partially outside of the outer tube and bent so as to place the catheter assembly into a folded configuration;
the inner catheter tube and the outer tube being movable relative to one another so that a bending element of the bendable region of the inner catheter tube is moved into the lumen of the outer tube, thereby straightening the inner catheter tube so as to place the urinary catheter assembly into a straight ready to use configuration; and
wherein the outer tube and inner catheter tube are configured to be inserted into a urethra.

2 . The urinary catheter product of claim 1 , wherein the inner catheter tube has a proximal end portion and a distal end portion, and the bendable region is between the proximal end portion and the distal end portion.

3 . The urinary catheter product of claim 2 , wherein the bendable region is a separate component connected to the proximal end portion and the distal end portion of the inner catheter tube.

4 . The urinary catheter product of claim 2 , wherein when the catheter assembly is in the folded configuration, the distal end portion of the inner catheter tube is located within the outer tube.

5 . The urinary catheter product of claim 1 , wherein when the catheter assembly is in the folded configuration, the bendable region is adjacent a proximal end portion of the outer tube.

6 . The urinary catheter product of claim 2 , wherein when the catheter assembly is in the folded configuration, the proximal end portion of the inner catheter tube is located within the outer tube.

7 . The urinary catheter product of claim 1 , wherein when the catheter assembly is in the folded configuration, the bendable region is adjacent a distal end portion of the outer tube.

8 . The urinary catheter product of claim 1 , wherein the catheter assembly includes a biasing member that biases the catheter assembly toward the straight ready to use configuration.

9 . The urinary catheter product of claim 8 , wherein the biasing member comprises a spring.

10 . The urinary catheter product of claim 9 , wherein the spring is positioned between a distal end of the outer tube and the inner catheter tube.

11 . The urinary catheter product of claim 1 , wherein the bending element comprises a spring.

12 . The urinary catheter product of claim 1 , wherein the bending element comprises a notch.

13 . The urinary catheter product of claim 1 , wherein the bending element comprises a slit.

14 . The urinary catheter product of claim 1 , further including at least one sleeve extending over at least a portion of the inner catheter tube and/or at least a portion of the outer tube.

15 . The urinary catheter product of claim 14 , wherein the sleeve extends over the outer tube.

16 . The urinary catheter product of claim 15 , wherein the sleeve extends proximally beyond a proximal end of the outer tube.

17 . The urinary catheter product of claim 15 , wherein the sleeve extends over a portion of the inner catheter tube.

18 . The urinary catheter product of claim 14 , wherein the at least one sleeve comprises a first sleeve and a second sleeve, wherein the first sleeve extends over the outer tube and the second sleeve extends at least a portion of the inner catheter tube.

19 . The urinary catheter product of claim 1 , further including a packaging, wherein the catheter assembly in the folded configuration is located in the packaging.

20 . The urinary catheter product of claim 19 , wherein the packaging is configured to maintain the urinary catheter assembly in the folded configuration.

21 . The urinary catheter product of claim 1 , wherein the urinary catheter assembly further includes a activation mechanism for moving the urinary catheter assembly from the folded configuration to the straight ready to use configuration.

22 .- 23 . (canceled)
