    摘要： Devices and methods are disclosed for stabilizing tissue within a patient's body during a surgical operation to provide a relatively motionless surgical field, such as during a coronary artery bypass graft procedure. The devices include tissue stabilizers which engage and provide stabilization to a targeted area of tissue and further have the ability to engage and manipulate some portion of tissue within or adjacent the targeted area to improve the surgical presentation of that portion of tissue. The tissue stabilizer typically has one or more stabilizer feet which have a first foot portion configured to provide stabilization to the targeted tissue and a second foot portion moveable relative to the first foot portion for manipulating a portion of tissue to improve the surgical presentation.

    摘要： Continuous-feed plasma treater systems are designed to treat continuous substrates, such as webs or films, by continuously feeding the substrates through an enclosure having a plasma discharge that alters the substrate's surface properties in some desirable fashion. The plasma discharges are generated by one or more electrode assemblies housed within the enclosure. In general, the plasma treater systems of the present invention have one or more cylinder-sleeve electrode assemblies and/or one or more cylindrical cavity electrode assemblies. A cylinder-sleeve electrode assembly comprises a cylinder electrode and a sleeve electrode positioned with its concave face facing and substantially parallel to the cylinder electrode to form an annular gap between the outer surface of the cylinder electrode and the inner surface of the sleeve electrode. The electrode assembly is adapted to be excited to generate a plasma within the annular gap to form a primary plasma discharge zone for exposure of the plasma to a substrate. A cylindrical cavity electrode assembly comprises (1) a cavity electrode, having a cylindrical bore and a wall slot running parallel to the cylindrical bore and exposing the cylindrical bore; (2) a cylinder electrode coaxially positioned within the cylindrical bore of the cavity electrode to form an annular gap between the outer surface of the cylinder electrode and the surface of the cylindrical bore, the annular gap forming a primary plasma discharge zone; and (3) a treater drum positioned adjacent to the wall slot of the cavity electrode. During operations, the substrate is translated past the wall slot by the treater drum and exposed to plasma species that are convected from the primary plasma discharge zone to the wall slot. Plasma treater systems of the present invention can be used (a) to treat substrates in an efficient cost-effective manner and (b) to produce treated substrates having superior surface properties as compared to those generated using prior-art systems, such as corona-type discharge systems.

    摘要： A heart retractor links lifting of the heart and regional immobilization which stops one part of the heart from moving to allow expeditious suturing while permitting other parts of the heart to continue to function whereby coronary surgery can be performed on a beating heart while maintaining cardiac output unabated and uninterrupted. Circumflex coronary artery surgery can be performed using the heart retractor of the present invention. The retractor includes a plurality of flexible arms and a plurality of rigid arms as well as a surgery target immobilizing element. One form of the retractor can be used in minimally invasive surgery, while other forms of the retractor can accommodate variations in heart size and paracardial spacing.
