The needle-free injection system may include one or more orifices.
Claims16
A needle-free jet injection device for delivering a fluid into an internal organ, the device comprising:
- a rigid end effector including at least one injection orifice, the end effector being adapted to be positioned within a prostatic section of a patient's urethra adjacent the patient's prostate gland;
- a fluid reservoir in fluid communication with the end effector;
- and
- an ejection mechanism adapted to eject the fluid from the fluid reservoir through the end effector and out of the injection orifice with sufficient pressure to penetrate the prostate gland while preserving functionality of the prostate gland.

A needle-free jet injection device for delivering a fluid into an internal organ, the device comprising:
- a fluid reservoir;
- an extension structure adapted to be inserted within a patient's urethra so that a distal region of the extension structure is positioned adjacent the patient's prostate gland, wherein the distal region of the extension has an at least partially hollow interior that fluidly communicates with the fluid reservoir;
- and
- an ejection mechanism adapted to eject the fluid from the fluid reservoir through the extension structure and out of a plurality of injection orifices provided in the distal region of the extension structure.
