First Claim
Patent Images
1. A needle-free jet injection device for delivering a fluid into an internal organ, the device comprising:
- a rigid end effector including a plurality of orifices;
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 orifices with sufficient pressure to penetrate the organ while preserving functionality of the organ.

Abstract
A needle-free injection system is described. The needle-free injection system may be suitable for injection into internal organs. In one embodiment, the needle-free injection system includes an elongate end effector that may or may not include a curved or angled distal end. The needle-free injection system may include one or more orifices.

28. A method for delivering a fluid into an internal organ of a living organism, the method comprising:
-
inserting a first part of a needle-free injection system having a rigid end effector including a plurality of orifices into a living organism'"'"'s body such that an internal organ within the body is contacted by at least some of the orifices in the needle-free injection system;
maintaining a second part of the needle-free injection system outside of the body; and
injecting a fluid through the orifices and into the internal organ such that the fluid penetrates the organ without destroying the functionality of the organ. - View Dependent Claims (29, 30, 31, 32)
