Abstract
A valve for a bladder control device including an elongate housing having a valve seat disposed therein. A stopper is also disposed within the housing and is moveable between a first position in which the stopper engages the valve seat and a second position wherein the stopper is moved distally of the valve seat. A tension spring can be connected to the stopper to biases the stopper toward the valve seat. A lumen is defined through the housing having a first portion disposed distally of the valve seat having a diameter approximately equal to a diameter of the stopper. A second portion of the lumen disposed distally of the first portion has a greater diameter than the first portion of the lumen. Yet a third portion of the lumen disposed distally of the second portion has a diameter less than that of the first portion.
Claims19
A valve for a bladder control device, comprising:
- an elongate housing having a proximal end and a distal end, and a lumen extending therethrough;
- a valve seat disposed within the housing;
- a stopper disposed within the housing and moveable between a first position engaging the valve seat and a second position disposed distally of the valve seat;
- and
- a tension spring connected to the stopper disposed to biases the stopper toward the valve seat, the spring being under greater tension loading when the stopper is in the second position than when the stopper is in the first position.
A valve for a bladder control device, comprising:
- an elongate housing having a proximal end, a distal end, and a lumen extending therethrough;
- a valve seat disposed within the housing;
- a stopper disposed within the housing and moveable between a first position engaging the valve seat and a second position disposed distally of the valve seat, the stopper includes a proximal portion having a first diameter and a distal portion having a second diameter greater than the first diameter;
- a spring connected to the stopper to bias the stopper toward the valve seat;
- and
- wherein a first portion of the lumen is disposed distally of the valve seat and has a diameter approximately equal to the second diameter of the stopper, and the stopper is slidably disposed in the first portion of the lumen for movement between the first and second positions, and a second portion of the lumen, having a diameter greater than the diameter of the first portion of the lumen, is disposed distally of the first portion of the lumen.
