    摘要: A fastener for securing adjacent layers of body tissue to each other and being configured and composed of a material so as to emerge from the body tissue after a limited period of time. The fastener includes a backspan and at least two prongs extending from the backspan. Each prong has a tapered tip culminating in a sharp point. The prongs each include a shaft having a cylindrical portion of uniform diameter. In one embodiment, the prong includes a serrated portion having a plurality of notches spaced apart so as to define ridge portions there between. In another embodiment, the prong includes a pair of tapered projecting surfaces extending around a portion thereof.

    摘要: A blade actuating assembly is provided which permits selective reciprocal movement of a tissue cutting blade positioned at a distal end of an optical trocar assembly from a non-deployed position to a deployed position and back to a non-deployed position. The trocar assembly has an optical obturator which includes a sleeve having a longitudinal bore between a proximal end and a distal end. The longitudinal bore of the sleeve is configured to receive at least a portion of an endoscope or like image transferring system. An objective optical member, such as an optical window is positioned at the distal end of the sleeve and is provided to permit optical images to pass into the longitudinal bore of the sleeve and to permit illumination light to pass to the surgical site.

    摘要: A meniscal fastener applying device for repairing tears in the meniscus of the knee. The device includes a handle assembly and an elongated body portion attached thereto. The handle assembly is operatively attached to a firing mechanism to remotely actuate a firing bar. The firing bar is movably positioned within the elongated body portion to engage and eject a fastener from within the elongated body portion. The elongated body portion includes a support casing which is preferably constructed from stainless steel. The support casing has a cylindrical proximal cross-section that tapers into a distal cross-section having planar top and bottom surfaces. The distal end of the elongated body portion further includes a pair of locator barbs and a tapered distal face.
