1. A method of interventional surgery comprising:
- inserting an actuator within a body of a vascularized organism and stopping the actuator adjacent a target region within a vessel of the vasculature of the body, the actuator including an expandable section incorporating a needle, the actuator being operable between an unactuated condition in which the expandable section is in a furled state and an actuated condition in which the expandable section is in an unfurled state;
causing the expandable section to change from the furled state to the unfurled state, to cause the needle to move in a substantially perpendicular direction relative to a wall of the vessel to produce an opening therein; and
delivering a therapeutic or diagnostic agent from the needle to the target region via the opening in the wall of the vessel.

Abstract
A method of interventional surgery is described. The method may include inserting an actuator within a body of a vascularized organism and positioning the actuator adjacent a target region within a vessel of the body. The actuator is operated to cause a needle thereof to move in a substantially perpendicular direction relative to a wall of the vessel to produce an opening therein. A therapeutic or diagnostic agent may be delivered by the needle to the target region via the opening in the vessel wall.

7. A method of interventional surgery comprising:
-
inserting an actuator within a body of a vascularized organism and stopping the actuator adjacent a target region within a vessel of the vasculature of the body, the actuator including an actuator body having a distal end and a proximal end, a central expandable section including a needle and located between the distal end and the proximal end, the actuator being operable between an unactuated condition in which the expandable section is in a furled state and an actuated condition in which the expandable section is in an unfurled state; and
operating the actuator to cause the expandable section to change from the furled state to the unfurled state such that the needle moves in an approximately perpendicular direction relative to a central longitudinal axis of the actuator body from a position inside the actuator body to a position outside the actuator body.

8. A method of catheter-based interventional surgery comprising:
-
inserting and manipulating a distal end of a catheter within a body of a vascularized organism, the distal end of the catheter including an actuator;
positioning the actuator adjacent a target region of a vessel of the vasculature of the body and terminating movement of the distal end of the catheter;
operating the actuator to cause an expandable section thereof to change from a furled state to an unfurled state such that a microneedle at the expandable section moves in a substantially perpendicular direction relative to a wall of the vessel, from a position inside a body of the actuator to a position outside the body of the actuator, to produce an opening in the wall of the vessel. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method of interventional surgery comprising:
-
inserting an actuator within a body and stopping the actuator adjacent a target region within a vessel of the vasculature of the body, the actuator being operable between an unactuated condition in which an expandable section thereof is in a furled state and an actuated condition in which the expandable section is in an unfurled state, and a plurality of needles at the expandable section; and
operating the actuator to cause the expandable section to change from the furled state to the unfurled state such that the needles move in an approximately perpendicular direction relative to a central longitudinal axis of the actuator from a position inside the actuator to a position outside the actuator. - View Dependent Claims (16, 17, 18, 19)
