  • Patent number: 5236443
    Abstract: A surgical suturing assembly and method of suturing are provided. The suturing assembly comprises a surgical needle having a pin within a casing or sheath having an aperture, wherein the pin of the needle is within the casing aperture. A suture is attached to the needle, casing or both. In use, a surgeon slides the pin of the needle, forcing the sharpened distal point of the needle to project through the distal opening of the casing. Once the distal portion of the needle/casing assembly penetrates the tissue, the sliding force is released or retracted which causes the needle to return to its original position, leaving an unsharpened point for further manipulation. The chance of needle-stick is thus greatly reduced.

  • Patent number: 5129558
    Abstract: A sewing needle has a main body 10 and a closed loop 18 of a resilient filament material rigidly secured to the rear end of the main body and lying a single common plane with the lengthwise axis of the main body. In unstressed condition, the filament has an open diamond configuration allowing a sewing thread to be easily passed through it. As the needle is pulled through the fabric, the loop collapses under the forces imposes on its sides by the fabric and thereafter expands to reassume its unstressed configuration. The rigid securement of the loop to the main body of the needle ensures that the loop remains in a single common plane with the needle axis as it collapses upon passage through the fabric and as it expands to its unstressed configuration following such passage.

  • Patent number: 4926860
    Abstract: Arthroscopic instrumentation for use in arthroscopic surgery and similar procedures. The instrumentation includes a cannula having a curved lumen and an elongated, flexible normally straight shape memory alloy probe. The probe is insertable into the lumen of the cannula, which in turn can be directed to a hard to reach operative site. The cannula causes the probe to bend as it passes the curves of the cannula, but the shape memory character of the probe causes the probe to exit the distal end of the cannula in a substantially straight orientation.
