  • Patent number: 9011355
    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.

  • Patent number: 9006604
    Abstract: A system and method for precision cutting using multiple laser beams is described. The system and method includes a combination of optical components that split the output of a single laser into multiple beams, with the power, polarization status and spot size of each split beam being individually controllable, while providing a circularly polarized beam at the surface of a work piece to be cut by the laser beam. A system and method for tracking manufacture of individual stents is also provided.

  • Patent number: 8986339
    Abstract: A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.

  • Patent number: 8845684
    Abstract: A tissue closure device includes a main body, a sheath, and a biasing member. The main body has a plurality of resilient arms that each extend from a proximal end to a distal tip. The resilient arms are movable between an open configuration in which the distal tips are radially spaced apart from the longitudinal axis of the main body and from each other and a closed configuration in which the distal tips abut one another at or near the longitudinal axis. The sheath is longitudinally slideable on the main body to move the arms between the open and closed configurations. The biasing member causes the sheath to bias the arms toward the closed configuration.

  • Publication number: 20140200655
    Abstract: Intravascular cardiac restraining implants designed for treatment of heart disease and heart failure and methods for their use. The disclosed implants can be used to reshape or reinforce a diseased, weakened or distended portion of a patient's heart to counteract heart disease and heart damage. An intravascular cardiac restraining implant may include a first tissue anchor configured for implantation in a first region of a coronary vein, a second tissue anchor configured for implantation in a second region of the coronary vein, and at least one elongate member coupled to the first tissue anchor and the second tissue anchor. In one embodiment, the at least one elongate member may be a spring or a similar device configured for biasing the first and second tissue anchors toward one another, thus reshaping or reinforcing a diseased, weakened or distended portion of a patient's heart.
