Abstract
An artificial urinary sphincter system includes a cuff implantable around a portion of a urethra, an implantable pressure-regulating reservoir, and a deflation assembly attachable between the cuff and the implantable pressure-regulating reservoir. The deflation assembly includes a valve that selectively restricts movement of the fluid from the cuff to the pressure-regulating reservoir, a base and an activation surface opposite the base. The activation surface includes an outer peripheral rim surrounding a pad that is movable to displace the valve to allow the fluid to flow from the cuff to the pressure-regulating reservoir. An entirety of the pad is recessed relative to the outer peripheral rim such that the outer peripheral rim defines a maxima of the activation surface.
Claims19
An artificial urinary sphincter system comprising:
- a cuff implantable around a portion of a urethra;
- an implantable pressure-regulating reservoir;
- and
- a deflation assembly attachable between the cuff and the implantable pressure-regulating reservoir, the deflation assembly comprising:
- a valve that selectively restricts movement of a fluid from the cuff to the pressure-regulating reservoir,
- a base and an activation surface opposite the base, the activation
- surface including an outer peripheral rim surrounding a pad that is
- movable to displace the valve to allow the fluid to flow from the cuff to the pressure-regulating reservoir;
- wherein an entirety of the pad is recessed relative to the outer peripheral rim such that the outer peripheral rim defines a maxima of the activation surface.
An artificial urinary sphincter system comprising:
- a cuff implantable around a portion of a urethra;
- a pressure-regulating reservoir;
- and
- a deflation assembly separate from the pressure-regulating reservoir and separate from the cuff, the deflation assembly connectable between the cuff and the pressure-regulating reservoir, the deflation assembly enclosing a valve that selectively restricts movement of a fluid from the cuff to the pressure-regulating reservoir;
- wherein the deflation assembly comprises a base and an activation surface opposite the base, the activation surface including an outer peripheral rim and a pad that is recessed in a concave configuration relative to the outer peripheral rim such that the outer peripheral rim defines a maxima of the activation surface;
- wherein the pad is movable to displace the valve to allow movement of the fluid from the cuff to the pressure-regulating reservoir.
An artificial urinary sphincter system comprising:
- a cuff implantable around a portion of a urethra;
- a pressure-regulating reservoir;
- and
- a deflation assembly separate from the pressure-regulating reservoir and separate from the cuff, the deflation assembly connectable between the cuff and the pressure-regulating reservoir, the deflation assembly enclosing a valve that selectively restricts movement of a fluid from the cuff to the pressure-regulating reservoir;
- wherein the deflation assembly comprises a base and an activation surface opposite the base, the activation surface including an outer peripheral rim and a pad that is recessed in a concave configuration relative to the outer peripheral rim;
- wherein the pad is movable to displace the valve to allow movement of the fluid from the cuff to the pressure-regulating reservoir;
- wherein the artificial urinary sphincter system is characterized by an absence of a pump.
An artificial urinary sphincter system comprising:
- a cuff implantable around a portion of a urethra;
- a body-implantable pressure-regulating reservoir provided to pressurize fluid contained in the system;
- and
- a deflation assembly attachable between the cuff and the body-implantable pressure-regulating reservoir, the deflation assembly comprising:
- an activation surface including a pad recessed relative to a rim of the activation surface;
- and
- a valve located between a base of the deflation assembly and the recessed pad, the valve provided to selectively restrict movement of the fluid in the cuff from moving to the pressure-regulating reservoir;
- wherein the recessed pad is movable to displace the valve to allow movement of the fluid from the cuff to the pressure-regulating reservoir.
