  • Publication number: 20200345342
    Abstract: According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly and a biasing element. The driver is disposed in mechanical cooperation with the drive assembly. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.

  • Publication number: 20190053828
    Abstract: An occlusion device includes a body having a plurality of layers and defining a first diameter. Each layer of the plurality of layers is releasably coupled to a respective inwardly-adjacent layer. An outermost layer of the plurality of layers is removable from the respective inwardly-adjacent layer. Removal of the outermost layer reduces an outer diameter of the body from the first diameter to a second diameter that is less than the first diameter.

  • Publication number: 20180110512
    Abstract: According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a drive assembly, a driver, a needle assembly, and a follower. The drive assembly includes a first helical groove. Rotation of the drive assembly in a first direction causes distal translation of the driver with respect to the drive assembly. The needle assembly is disposed in mechanical cooperation with the driver. Distal translation of the driver causes a corresponding distal translation of the needle assembly. The follower is configured to engage the first helical groove of the drive assembly. When the follower is engaged with the first helical groove, rotation of the drive assembly in the first direction causes distal translation of the follower with respect to the drive assembly.

  • Patent number: 8882785
    Abstract: 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.

  • Patent number: 8617190
    Abstract: 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.

  • Patent number: 8075573
    Abstract: Provided is an endoscopic suturing system for joining internal body tissues in a variety of procedures. The system comprises a suturing capsule releasably mountable to the distal end of an endoscope and capable of forming multiple stitches in tissue at a plurality of locations without requiring withdrawal of the capsule from the patient between stitches. Also enclosed is a suture lock to secure the placed stitch that is delivered by a device introduced through the working channel of the indwelling endoscope. Suitable control handles for the suturing capsule and for the suture lock delivery device positioned at the proximal end of the endoscope are provided to facilitate operation by the user.

  • Patent number: 7972578
    Abstract: A device and method is provided 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 an elastic portion and a plug member. A fluid sample is delivered to the container and the device is subjected to centrifugation whereby the centrifugal load causes the elastic portion of the separator to deform so that the separator migrates into the fluid sample and stabilizes between the heavier and lighter fractions of the fluid sample. The elastic portion of the separator will resiliently return to its initial configuration upon termination of the centrifugal load such that the elastic portion sealingly engages the container and separates the heavier and lighter fractions of the fluid sample.
