Microfabricated surgical device for interventional procedures
First Claim
1. An actuator for an interventional surgical procedure comprising:
- an actuator body having a distal end and a proximal end;
a central expandable section located between the distal end and the proximal end, said expandable section operable between an unactuated condition in which said expandable section is in a furled state and an actuated condition in which said expandable section is in an unfurled state; and
a needle at said expandable section, said needle being movable in an approximately perpendicular direction relative to a central longitudinal axis of said actuator body from a position within said actuator body to a position outside of said actuator body when said expandable section is caused to change from said furled state to said unfurled state.

Abstract
An actuator for an interventional surgical procedure is described. The actuator may include an actuator body having a distal end and a proximal end. A central expandable section is located between the distal end and the proximal end. The expandable section is 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. A needle is located at the expandable section. The needle is moveable in an approximately perpendicular direction relative to a central longitudinal axis of the actuator body from a position within the actuator body to a position outside of the actuator body.

13. A microfabricated surgical device for an interventional surgical procedure comprising:
-
a catheter having a distal end for insertion into and manipulation within a body of a vascularized organism and a proximal end for providing a user with control over the manipulation of the distal end of the catheter within the body;
an actuator joined to the distal end of the catheter, said actuator including an actuator body and a needle joined to an expandable section of the actuator body such that said needle is located within said actuator body when said actuator is in an unactuated condition and outside of said actuator body when said actuator is in an actuated condition, said needle being, movable along a path substantially perpendicular to a central longitudinal axis of said actuator body when said actuator changes from the unactuated condition to the actuated condition; and
fluid connections at the distal end of the catheter and a proximal end of said actuator to supply a therapeutic or diagnostic agent to said needle, and to provide an activating fluid to said actuator to cause said actuator to change from the unactuated condition to the actuated condition. - View Dependent Claims (14, 15, 16, 17, 18, 19)
