Abstract
A medical device for delivering a material using a pressurized fluid includes an enclosure having a first chamber and a second chamber separated by a membrane, and an outlet, and a pin configured to move within the enclosure between a first position and a second position, where a proximal end of the pin blocks the outlet when the pin is in the first position.
Claims20
A medical device configured to deliver a material using a pressurized fluid, the device comprising:
- an enclosure having a first chamber and a second chamber separated by a membrane, and an outlet;
- and
- a pin configured to move within the enclosure between a first position and a second position,
- wherein a proximal end of the pin is configured to block the outlet when the pin is in the first position.
A medical device configured to deliver a material, the device comprising:
- a body having an input opening for receiving a pressurized fluid and an output opening for delivering the material;
- an enclosure having a first chamber and a second chamber;
- a membrane including a plurality of apertures, wherein the membrane is disposed between the first chamber and the second chamber;
- and
- a pin configured to move within the enclosure between a first position and a second position, wherein the pin is configured to close the output opening in the first position.
A method for controlling a delivery of material delivery to a body of a patient, the method comprising:
- actuating an actuator to cause an enclosure containing a pressurized fluid to release the pressurized fluid from the enclosure;
- supplying the material to a first chamber;
- causing a pin in a second chamber, adjacent the first chamber, to move from a closed position to an open position, wherein the open position is configured to allow mixture of a material in the second chamber and the propellant fluid to pass from the second chamber;
- and
- supplying the mixture of the material in the second chamber and the propellant fluid to a target site.
