    摘要: A bioabsorbable rivet and pin fastener is formed as an elongated unit that may be used for anchoring, or for attachment of a fixation plate. The rivet has a head mechanically connected to two or more legs that extend generally distally from the head and may flex outwardly from a central rivet axis. The pin is integral with the rivet and oriented along the central axis by a connection such as a web or a plurality of braces, forming an integral, aligned, one-piece assembly that may, for example, be molded as a single piece. The connection breaks under force as the pin is driven into the rivet, so that the pin contacts internal surfaces of the legs and pushes the legs outward into frictional engagement with the surrounding bone. The one-piece assembly may be formed in a gated mold having a central pin with a relief passage that defines the braces between upper and lower portions of the rivet. The braces so formed at the weld line readily part from the mold, and are easily sheared when the pin is advanced during installation of the rivet.

    摘要: A bioabsorbable rivet and pin fastening device that may be used for attachment of a fixation plate to bone is described herein. The rivet having a head that is mechanically connected to two or more legs that extend generally distally from the head. The pin being radially compressible and less compliant than the legs of the rivet. The pin when inserted into the rivet will contact the internal surface of said legs to apply force on said legs in a direction perpendicular to the central axis to frictionally engage with the adjacent bone.

    摘要: A surgical fastening system includes a fastener having a plurality of individual fastener pairs each having a piercing element with a pin that pierces the tissue to be repaired and a receiver portion that interlocks with the pin of a corresponding piercing element. A fastener dispenser holds the piercing elements and receiver elements in relative juxtaposition and in a predetermined geometric configuration, such as a circle. After the tissues to be joined are positioned between the piercing and receiving elements held in the dispenser, the dispenser is adjusted to draw the elements together capturing the tissue therebetween. The dispenser then pushes the piercing elements through the tissue and into the receiving elements causing the elements to interlock. Because the anastomosed junction is formed by a plurality of independent pairs, the junction retains flexibility. When used to anastomose a tubular organ, the fastener allows radial expansion of the organ permitting peristalsis.

    摘要: A biocompatible fastener that may be used for attachment of a fixation plate to bone is described herein, where the fastener has features that facilitate its deployment in a surgical environment. The fastener is composed of a screw, having a threaded shaft and slotted head, and a detachable body that is used for deploying the screw and is then broken away and discarded. The slot in the head of the screw has stress concentrating notch features that direct the fracture lines into the screw head upon detachment of the secondary body, thus ensuring that the screw head surface remains smooth after deployment. A suitable driver for applying the fastener is also described.

    摘要: The present invention relates to tissue-supporting medical devices and drug delivery systems, and more particularly to tubular flexible stents that are implanted within a body lumen of a living animal or human to support the organ, maintain patency and/or deliver drugs or agents. The tubular flexible stent has a cylindrical shape defining a longitudinal axis and includes a helical section having of a plurality of longitudinally oriented strut members and a plurality of circumferentially oriented hinge members connecting circumferentially adjacent strut members to form a band. The band is wrapped about the longitudinal axis in a substantially helical manner to form a plurality of helical windings. At least one connector member extends between longitudinally adjacent helical windings of the band.
