    摘要： An endoscopic suturing device that can be employed to suture tissue using endoscopic techniques to place one or more stitches in tissue during a single intubation of an endoscope. The suturing device may include a suturing capsule with a suction chamber that is configured to capture tissue that is to be sutured. A needle is movable along a pathway across the suction chamber to penetrate and place stitches in the captured tissue. A catch is located distal to the suction chamber to receive and retain the suture during a stitching sequence. The catch may be movable along the needle pathway and configured to release the suture when the catch moves a predetermined distance along the pathway. The catch may be configured so that a predetermined amount of force is required to move the catch the predetermined distance required to release the suture.

    摘要： A device and method for separating heavier and lighter fractions of a fluid sample. The device includes a plurality of constituents comprising a container and a composite element in the container. The composite element is a separator comprising at least two components and more particularly, a bellows with a seal body, a low-density float and a high-density ballast. A fluid sample is delivered to the container and the device is subjected to centrifugation whereby the centrifugal load causes the seal body of the separator to deform so that the separator migrates through the fluid sample and then stabilizes between the heavier and lighter fractions of the fluid sample. The seal body of the separator will resiliently return to its initial configuration upon termination of the centrifugal load such that the seal body sealingly engages the container and the composite element separates the heavier and lighter fractions of the fluid sample.

    摘要： A surgical portal apparatus includes a housing and a cannula member. The housing includes a seal mount and a flexible housing wall. The cannula member is connected to the housing and defines a longitudinal axis and passageway. The seal mount has an internal seal. The flexible housing wall is dimensioned to permit both axial and radial movement of the seal mount with respect to the longitudinal axis between a first position of the seal mount and a plurality of second positions of the seal mount. The seal mount may be biased by a biasing member toward the first position. In an embodiment, the biasing member is a spring that is engageable with the cannula member and the seal mount.

    摘要： A device and method is provided for separating components of a fluid sample. The device includes a plurality of constituents comprising a container, a liner in the container, a closure for the container and a composite element. The composite element is a seal plug with a density between the densities of the components of the fluid sample is releasably engaged with the container closure and with the liner. A needle cannula is used to deposit a fluid sample in the liner and the entire device is placed in a centrifuge. The centrifugal load causes the seal plug to separate from the closure and causes the liner to expand outwardly against the container. The seal plug migrates into the fluid sample and stabilizes between the densities of the components of the fluid sample. The liner will resiliently return to its initial configuration upon termination of centrifugal load such that the liner sealingly engages the seal plug and separates the components of the fluid sample.

    摘要： A suture lock fastening device to cinch a suture in a suture lock, cut the suture end, and deploy the suture lock in response to a single movement of a user. The fastening device includes a fastening head with a retainer that is configured to hold a suture lock in the fastening head. To release the suture lock from the fastening head, the retainer is irreversibly deformed. The fastening device may include an axially movable cutter with a cutting edge to sever the ends of the suture close to the suture lock. A threading device may be preloaded into the fastening device to facilitate threading the suture through the fastening device.
