  • Methods for laser cutting tubing to make medical devices
    Patent number: 8779328
    Abstract: Methods for making devices include providing a tubular member to be formed into a device, placing a removable sacrificial block material in the lumen of the tubular member and laser cutting the tubular member. A tubular member made from nickel-titanium alloy can be tightly adhered to a sacrificial sleeve utilizing the phase changes associated with nickel-titanium. A mandrel which includes an enlarged diameter section causes the workpiece to expand slightly within its elastic deformation range to dislodge islands from the workpiece. Such a mandrel could be formed from a tubular member which has a central lumen that can be used to deliver a pressurized medium to “blast” islands from the workpiece.

  • Methods and Devices for Treating Hypertension
    Publication number: 20140180181
    Abstract: Devices, systems and methods are described which control blood pressure and nervous system activity by stimulating baroreceptors. By selectively and controllably activating baroreceptors and/or nerves, the present invention reduces blood pressure and alters the sympathetic nervous system; thereby minimizing deleterious effects on the heart, vasculature and other organs and tissues. A baroreceptor activation device or other sensory activation device is positioned near a dermal bone to provide the treatment.

  • Electrochemical formation of foil-shaped stent struts
    Patent number: 8747649
    Abstract: An apparatus and method for electrochemically treating the struts of an intravascular stent is disclosed. An intravascular stent is mounted in a chamber and is electrochemically treated in order to remove a portion of the stent struts in order to form an airfoil shape. The airfoil-shaped stent struts will reduce turbulent blood flow in the vasculature in which the stent is implanted thereby improving clinical outcome.

  • AGENT DELIVERY CATHETER HAVING RADIALLY EXPANDABLE CENTERING SUPPORT MEMBER
    Publication number: 20140121603
    Abstract: A catheter for delivering an agent to an injection site in a wall of a patient's body lumen, with an elongated shaft having a needle-through lumen slidably containing a needle therein, and an expandable member on the distal shaft section which has a collapsed configuration and a radially expanded configuration. In the radially expanded configuration, the expandable member supports the shaft in a position spaced away from the body lumen wall, and the needle slidably exits the needle-through lumen in the extended configuration through the port spaced away from the body lumen wall as a portion of the expandable member maintains the position of the port section of the shaft in the body lumen. The expandable member typically has an open-walled, helical, or lobed configuration providing a perfusion path along the expandable member.
