Abstract
A method of delivering a urological device includes providing a catheter and a urological valve that can be retained within the catheter; advancing the catheter toward a bladder neck of a user; withdrawing the catheter from the user; and deploying the urological valve out of the catheter into the bladder neck or urethra of the user.
Claims9
A method of delivering a urological device, the method comprising:
- providing a catheter and a urological valve that is adapted to be retained within the catheter, wherein the urological valve comprises a stem defining a lumen, a plurality of leaflets connected to a proximal portion of the stem, and a head part connected to the stem and extending radially around the plurality of leaflets;
- advancing the catheter toward a bladder neck of a user;
- withdrawing the catheter from the user;
- deploying the urological valve out of the catheter into one of the bladder neck and a urethra of the user;
- deploying the head part of the urological valve in a bladder of the user;
- and
- deploying the stem of the urological valve in the urethra of the user.

A method of delivering a urological device in treatment of a urology patient, the method comprising:
- providing a catheter and a urological valve that is adapted to be retained within the catheter, where the urological valve comprises leaflets that are movable to come together to provide the urological valve with a closed configuration and move apart to provide the urological valve with an open configuration;
- advancing the catheter toward a bladder neck of a user;
- withdrawing the catheter from the user and leaving the urological valve inside the user;
- adapting the leaflets to move in response to a urological pressure greater than 750 mm H2O applied for at least 5 seconds thus providing the urological valve with the open configuration and allowing urine to flow out of the user through the urological valve;
- and
- adapting the leaflets to remain in the closed configuration in response to a urological pressure of up to 900 mm H2O applied for less than 0.5 seconds.

A method of delivering a urological device, the method comprising:
- providing a catheter and a urological valve that is adapted to be retained within the catheter, wherein the urological valve comprises a plurality of leaflets that are engaged at a region of co-aption when the urological valve is in a closed configuration;
- advancing the catheter toward a bladder neck of a user;
- withdrawing the catheter from the user;
- deploying the urological valve out of the catheter into one of the bladder neck and a urethra of the user;
- configuring the plurality of leaflets to separate out of engagement in the region of co-aption in response to an applied urological pressure thus opening the urological valve allowing urine to flow out of the user through the urological valve;
- and
- configuring the plurality of leaflets to remain in the closed configuration in response to a urological pressure of up to 900 mm H2O applied for less than 0.5 seconds.
