    • A system for performing an end-to-side vascular anastomosis including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple. A second aspect of the invention includes an anastomotic fitting, having an inner flange over which the graft vessel is everted and an outer flange which contacts the exterior surface of the target vessel. A tailored amount of compression applied by the inner and outer flanges grips the target vessel wall and creates a leak-proof seal between the graft vessel and the target vessel. A third aspect of the invention has a flange to which the graft vessel attaches, by everting the graft vessel over the flange, and a plurality of staple-like members which attach the flange and the everted end of the graft vessel to the wall of the target vessel to form the anastomosis
    • 一种用于执行端对侧血管吻合的系统,包括吻合装置,应用仪器和用于进行血管吻合的方法。 该系统适用于在冠状动脉旁路手术中进行血管移植物和升主动脉之间的吻合,特别是在进入CABG手术中。 本发明的第一方面包括血管吻合缝。 第一构造具有两部分:锚定构件,与目标血管壁形成附件和联接构件,与旁路移植血管形成附件。 通过将连接构件插入到锚定构件中来完成吻合。 第二种结构将锚定构件和联接构件的功能结合成一体式吻合钉。 本发明的第二方面包括一种吻合装置,其具有内部凸缘,移植物容器在其上延伸,外部凸缘接触靶容器的外表面。 由内外法兰施加的定制的压缩量夹住目标血管壁,并在移植血管和靶血管之间产生防漏密封。 本发明的第三方面具有凸缘,移植管通过使移植物容器穿过凸缘而附接到该凸缘上,以及多个钉状构件,其将该移植物容器的凸缘和脱出端附接到 靶血管形成吻合

    • A device and method is provided for separating heavier and lighter fractions of a fluid sample. The device includes a plurality of constituents. The constituents include a container, a liner in the container and a composite element in the liner for separating the fractions of a fluid sample. The separator comprises a specific density at a target density range as defined by separable fluid components densities. A fluid sample is delivered to the liner and then the device is subjected to centrifugation whereby the centrifugal load causes the liner to deform and the composite element migrates into the fluid sample and stabilizes between the heavier and lighter fractions of the fluid sample. The liner will resiliently return to its initial configuration upon termination of the centrifugal load such that the liner sealingly engages the composite element and separates the heavier and lighter fractions of the fluid sample.
    • 提供了用于分离流体样品的较重和较轻馏分的装置和方法。 该装置包括多个成分。 组分包括容器,容器中的衬垫和用于分离流体样品的级分的衬垫中的复合元件。 分离器包括由可分离的流体组分密度所限定的目标密度范围的特定密度。 将流体样品输送到衬套,然后使装置进行离心,由此离心负载导致衬套变形,并且复合元件迁移到流体样品中并且在流体样品的较重和较轻部分之间稳定。 衬垫将在离心负载终止时弹性地返回到其初始构型,使得衬套密封地接合复合元件并分离流体样品的较重和较轻的部分。
