Abstract
A device can include a fitting including a first aperture, a second aperture, and a valve engageable to restrict fluid travel between the first and second apertures. The device can also include an elongate flexible shaft for coupling with the fitting. A piston can be disposed within the passage and configured to travel toward the distal end of the shaft while maintaining a fluid seal between first and second sides of the piston. Upon the valve being engaged, fluid pressure received at the first aperture can be translated to drive the piston toward the distal end of the shaft.
Claims20
A device for bronchoscopy, the device comprising:
- a fitting including a first aperture, a second aperture, and a valve selectively engageable to restrict fluid travel between the first and second apertures;
- an elongate flexible shaft sized and shaped to be fluidly coupled, at a proximal end of the shaft, with the second aperture of the fitting, the elongate flexible shaft defining a passage between the second aperture and a distal end of the shaft;
- and
- a piston sized and shaped to occlude the passage at a distal portion of the flexible shaft, the piston configured to travel toward the distal end of the shaft while maintaining a fluid seal, within the passage, between first and second sides of the piston;
- wherein upon the valve being selectively engaged to allow fluid travel between the first and second apertures, fluid pressure received at the first aperture of the fitting, via an external source of fluid pressure, is brought into fluid communication with the piston to drive the piston toward the distal end of the shaft.
A bronchoscopy system for accessing anatomy within a lung of a patient, the system comprising:
- a pump including a chamber and a first piston located inside the first chamber;
- and
- a check valve placement device including:
- a fitting including:
- a first fitting aperture fluidly connected to the pump;
- and
- a second fitting aperture;
- an elongate flexible shaft sized and shaped to be fluidly coupled, at a proximal end of the shaft, with the second fitting aperture, the elongate flexible shaft defining a passage between the second fitting aperture and a distal end of the shaft;
- and
- a second piston sized and shaped to occlude the passage at a distal portion of the flexible shaft, the piston configured to travel toward the distal end of the shaft while maintaining a fluid seal, within the passage, between first and second sides of the second piston;
- wherein the fitting valve is configured to allow fluid travel between the first and second fitting apertures, and the pump is thereby placed in fluid communication with the second piston such that movement of the first piston drives the second piston toward the distal end of the shaft, to eject an implantable endobronchial check valve from the distal end of the elongate flexible shaft.
The bronchoscopy system of claim 10, wherein:
- the fitting includes a fitting valve selectively engageable to restrict fluid travel between the first and second fitting apertures;
- during the fitting valve being selectively engaged to allow fluid travel between the first and second fitting apertures, the pump is placed in fluid communication with the second piston such that movement of the first piston drives the second piston toward the distal end of the shaft.
A method for bronchoscopy comprising:
- accessing anatomy within a lung of a patient via a distal end of a deployment device, the deployment device including:
- a fitting at a proximal end of the deployment device and including first and second apertures and a valve configured to selectively restrict fluid travel therebetween;
- and
- an elongate flexible shaft extending toward the distal end of the deployment device and defining a passage between the second aperture and a distal end of the shaft, the shaft including a piston disposed within the passage at a distal portion of the flexible shaft;
- selectively permitting, via the valve, fluid travel between the first and second apertures of the fitting;
- receiving fluid pressure at the first aperture of the fitting;
- and
- translating the fluid pressure into movement of the piston within the passage toward the distal end of the shaft.
