  • Patent number: 8562664
    Abstract: Medical devices are manufactured from fine grained materials, processed from of a variety of metals and alloys, such as stainless steel, cobalt-chromium and nickel-titanium alloys. A fine grained metal or alloy is formed from a specimen rapidly heated to its recrystallization temperature, and then subjected to high temperature, multi-axial deformation, for example, by heavy cross-forging or swaging. The deformed specimen may be cooled and reheated to a second recrystallization temperature. The metal or alloy in the specimen is then allowed to recrystallize, such that the grain size is controlled by quenching the specimen to room temperature. A desired medical device is then configured from the fine grained material. Decreasing the average grain size of a substrate material and increasing the number of grains across a thickness of a strut or similar component of the medical device increases the strength of the device and imparts other beneficial properties into the device.

  • Patent number: 8529591
    Abstract: An anastomotic instrument includes first and second units. The first unit is attached to a distal end portion of an insert section of an endoscope, and has a self-propellable apparatus and an anvil. The second unit is attached behind the first unit, and has a cartridge and a balloon. The insert section with the anastomotic instrument is inserted into the alimentary canal. In the alimentary canal, fluid is sucked out from space enclosed by the first and second unit through a suction port provided in the cartridge, to bring the space into negative pressure. While the alimentary canal is shrunk in the space, the second unit is shifted relative to the first unit. In a state where the shrunk alimentary canal is caught between the first and second units, a cutter resects living body tissue, and staples are struck to join edges of an incision of the alimentary canal.

  • Patent number: 8523885
    Abstract: An apparatus for regulating the functioning of a patient's organ or duct includes an elongated member having a first end and a second end. A fastener is disposed on the first end of the elongated member. The fastener is configured to engage the second end of the elongated member so that the elongated member forms a loop around the organ or duct. A tension element is disposed for movement within the elongated member. A drive element is associated with and engages the tension element for causing the tension element to control the tension applied by the elongated member against a patient's body organ or duct. A load monitor ensures that excessive pressure is not applied to a patient's body organ or duct.

  • Patent number: 8512360
    Abstract: Methods and devices for placing a target vessel in fluid communication with a source of blood and a target vessel. A conduit includes first portion adapted to be placed in fluid communication with a source of blood, such as a heart chamber, and a second portion adapted to be placed in fluid communication with a target vessel having a lumen, such as coronary artery. The first and second conduit portions are transverse to each other such that the conduit is generally T-shaped. The conduit lies on an exterior of the heart between the blood source and the target vessel and is configured to deliver blood in multiple directions into the lumen of the target vessel. For example, in an occluded coronary artery, blood flows both toward and away from the occlusion. The conduit may be flexible, rigid, collapsible or non-collapsible, and may be formed of synthetic vascular graft material, tissue, or a combination of the two.

  • Patent number: 8511310
    Abstract: The present invention, in an exemplary embodiment, provides a therapeutic medical appliance, delivery device and method of use. In particular, plug therapeutic medical appliances are provided that allow for the interventional treatment of pulmonary disorders such as defects characterized by pulmonary blebs and/or diffused destructive parenchymal disease. The plug therapeutic medical appliances themselves combine many of the excellent characteristics of both silicone and metal therapeutic medical appliances while eliminating the undesirable ones. In particular, these therapeutic medical appliances are preferably self-expanding in nature and allow the predetermined differential selection of relative hardness/softness of regions of the therapeutic medical appliance to provide additional patient comfort. An exemplary embodiment also provides a family of delivery devices that facilitate flexibility, durability and/or proper installation of one or more medical appliances in a single procedure.
