Abstract: An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand with open ends around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and/or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system also includes means to limit and/or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The preferred embodiment of the catheter includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.

A method of treating hypertension involves injecting an ablative fluid such as ethanol deep into zones in the wall of the renal artery such that the zones of fluid merge to form a circumferential ablation ring at a depth which ablates sympathetic nerves while minimizing injury to interior layers of the vessel wall.

Abstract: The invention provides an actuator for an electric motor and an electric motor including said actuator. The actuator includes one or more body formed from a dielectric elastomer, each body having at least one active region that is directly or indirectly coupled to a drive means. The active regions are arranged such that, in use, actuation thereof causes driven means to move with components in at least first and second directions, preferably within a plane of the body.

Abstract: The invention disclosed herein is a steering system that can be attached to a catheter, guidewire or obturator that consists of polymeric tubing with a center lumen and at least three off-axis lumens evenly spaced around the circumference of the device shaft. The distal sections of the off-axis lumens are formed to induce curvature of the tip of the device by a physician controlled pressure source, which may be foot activated. Forming the individual lumens to induce curvature of the shaft of the device in a certain direction is done by making one side of each lumen significantly longer, such as with a one sided corrugated configuration. These embodiments induce curvature in predetermined directions when pressurized.

Abstract: A cabinet knob construction which allows decorative aspects of the knob to be readily altered to vary the appearance of the hardware. A knob body mounted to the cabinet includes an axial bore which receives a magnetic disk and an insert sleeve. The sleeve has a non-circular interior configuration for receiving a metal stud affixed to a fascia member. The fascia member alters the front face of the knob body and the stud is maintained within the bore by the magnet. Removal of the fascia member allows replacement with a different member to alter the appearance of the hardware.
