    摘要： A device for interventional surgical or medical procedures is presented. The device is generally in the form of a balloon and is used to position itself or other working elements up against or through lumen walls in the body. The balloon is comprised of at least two materials of different elastic modulus, which allows for a flexible but relatively non-distensible, unfolding component of the balloon as well as an elastomeric, inflatable component of the balloon. The elastomeric component is fixedly attached to the flexible but relatively non-distensible component and together they form a pressure vessel that can be inflated within the lumens of the body.

    摘要： 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.

    摘要： Sympathetic nerves run through the adventitia surrounding renal arteries and are critical in the modulation of systemic hypertension. Hyperactivity of these nerves can cause renal hypertension, a disease prevalent in 30-40% of the adult population. Hypertension can be treated with neuromodulating agents (such as angiotensin converting enzyme inhibitors, angiotensin II inhibitors, or aldosterone receptor blockers), but requires adherence to strict regimens and often does not reach target blood pressure threshold to reduce risk of major cardiovascular events. A minimally invasive solution is presented here to reduce the activity of the sympathetic nerves surrounding the renal artery by locally delivering neurotoxic or sympathetic nerve-blocking agents into the adventitia. Extended elution of these agents may also be accomplished in order to tailor the therapy to the patient.
