US 2025/0017734 A1 · PIEZOELECTRIC NON-RETURN VALVE SHUT-OFF

Abstract

An implantable fluid operated device includes a fluid control system to transfer fluid between a fluid reservoir and an inflatable member. The fluid control system includes at least one fluid control device including at least one pump and at least one valve, or at least one combination pump and valve device. A seal is provided in the at least one fluid control device. In a first mode, the seal provides a seal between a fluid passageway and a fluid chamber of the fluid control device, to close the fluid control device. In a second mode, the seal is disengaged to open the fluid control device and allow fluid to flow between the fluid passageway and the fluid chamber. A seal retention device maintains a position of the seal when the fluid control device is open and fluid is flowing through the fluid control device.

Dependent claims

An implantable fluid operated inflatable device, comprising:

a fluid control system configured to control fluid flow between a fluid reservoir and an inflatable member, the fluid control system including:
at least one fluid passageway defined within a housing;
and
at least one fluidic component positioned in the at least one fluid passageway and configured to control a flow of fluid through the at least one fluid passageway, the at least one fluidic component including:
a fluid chamber;
a seal positioned between the at least one fluid passageway and the fluid chamber, and configured to seal an interface between the at least one fluid passageway and the fluid chamber in a closed position of the at least one fluidic component;
and
a seal retention mechanism configured to retain a position of the seal in an open position of the at least one fluidic component.

5 more elements

A fluid control system for an implantable fluid operated inflatable device, comprising:

at least one fluid passageway defined within a housing;
and
a fluid control device positioned in the at least one fluid passageway, the fluid control device including:
a base plate;
a diaphragm coupled to the base plate;
a fluid chamber defined between the base plate and the diaphragm;
an opening formed in the base plate, the opening connecting the fluid chamber to a fluid passageway of the fluid control device;
a seal provided at the opening and configured to form a seal between the fluid passageway and the fluid chamber in a closed state of the fluid control device;
and
a seal retention mechanism engaged with the seal and configured to retain a position of the seal in an open state of the fluid control device.
