1. A method of delivering fluid into a patient, comprising:
- maintaining a fluid agent under a substantially constant high pressure within a fluid reservoir;
opening a fluid control downstream of the fluid reservoir from a closed configuration to allow the fluid agent maintained at substantially constant high pressure to flow under high pressure from the fluid reservoir to a fluid aperture disposed downstream to the fluid control; and
delivering the fluid agent at high velocity out of the aperture and into the patient.

13. An apparatus for delivering fluid to a target location within a patient'"'"'s body, comprising:
-
a high pressure source adapted to maintain a fluid within a fluid reservoir at a substantially constant high pressure; a fluid delivery device comprising a fluid delivery aperture, wherein the delivery device is adapted to be positioned within the patient; and a fluid control disposed downstream the high pressure source and upstream the aperture, wherein the fluid control is configured to control the flow of fluid therethrough and to modify fluid communication between the fluid reservoir and the fluid delivery aperture. - View Dependent Claims (14, 15, 16, 17, 18, 19)
