Abstract

A method of treating urinary incontinence includes providing a urological device having a stem defining a lumen, a valve connected to a proximal portion of the stem and located in the lumen, and a head part connected to the stem and extending radially around the valve. The method further includes deploying the urological device by moving the stem and the valve and the head part out of a catheter and placing the head part and the valve of the urological device in a bladder of the user and placing the stem of the urological device in the urethra of the user.

First claim

What is claimed is:

1. A method of treating urinary incontinence, the method comprising:
providing a urological device having a stem defining a lumen, a valve connected to a proximal portion of the stem and located in the lumen, and a head part connected to the stem and extending radially around the valve;
locating the stem and the valve and the head part of the urological device inside of a catheter;
advancing the catheter into a urethra of a user;
deploying the urological device by moving the stem and the valve and the head part out of the catheter;
placing the head part and the valve of the urological device in a bladder of the user; and
placing the stem of the urological device in the urethra of the user.

2. The method of claim 1 , further comprising:
removing the catheter out of the urethra of the user.

3. The method of claim 1 , further comprising a tab connected to a distal portion of the stem, the method further comprising:
anchoring the tab at a meatus of the urethra and preventing migration of the stem into the bladder of the user.

4. The method of claim 1 , wherein the head part has a distal surface with a concave curvature, the method further comprising:
placing the concave curvature of the distal surface of the head part in contact with the bladder of the user.

5. The method of claim 1 , wherein the valve has a plurality of leaflets, the method further comprising:
placing the plurality of leaflets of the valve in the bladder of the user.

6. The method of claim 1 , wherein the valve has a plurality of leaflets that are engaged at a region of co-aption in a closed configuration, the method further comprising:
configuring the plurality of leaflets to separate out of engagement in the region of co-aption in response to an applied urological pressure thus allowing urine to flow out of the bladder and through the urological device.

7. The method of claim 1 , further comprising:
configuring the valve to open in response to a pressure greater than 750 mm H 2 O applied for at least 5 seconds.

8. The method of claim 1 , further comprising:
configuring the valve to remain in a closed configuration in response to a pressure of up to 900 mm H 2 O applied for less than 0.5 seconds.

9. A method of treating urinary incontinence, the method comprising:
providing a urological device having a stem defining a lumen, a valve having three leaflets that are connected to a proximal portion of the stem and located in the lumen, and a head part connected to the stem and extending radially around the valve;
locating the stem and the valve with the three leaflets and the head part of the urological device inside of a catheter;
advancing the catheter into a urethra of a user;
deploying the urological device by moving the stem and the valve with the three leaflets and the head part out of the catheter;
placing the head part and the valve with the three leaflets of the urological device in a bladder of the user, with the three leaflets of the valve touching each other in a region of co-aption, and placing the stem of the urological device in the urethra of the user and treating the urinary incontinence; and
configuring the three leaflets of the valve to separate one from each other in the region of co-aption in response to an applied urological pressure thus allowing urine to flow out of the bladder and through the urological device.

10. The method of claim 9 , further comprising:
anchoring a tab connected to the stem to a meatus of the urethra and preventing migration of the stem into the bladder of the user.

11. The method of claim 9 , further comprising:
configuring the three leaflets of the valve to separate one from each other in the region of co-option in response to a pressure greater than 750 mm H 2 O applied for at least 5 seconds.

12. The method of claim 9 , further comprising:
configuring the three leaflets of the valve to remain in a closed configuration in response to a pressure of up to 900 mm H 2 O applied for less than 0.5 seconds.
