  • Patent number: 6592473
    Abstract: A color-coded “user friendly” chart or display is provided for each putting green on a golf course, showing respective “extreme”, “hazard”, regulation” and “optimal” zones, respectively, and the chart or display may be changed easily and quickly and on a daily basis, if desired, whenever conditions on the putting green (such as pin location) are changed.
    Type: Grant

  • Patent number: 5968077
    Abstract: A sternotomy suture comprises a loop which passes around a split sternum and is twisted until double cabling begins at which point the suture is fastened to itself. The loop preferably comprises a single strand of wire with one end welded to an intermediate point of said strand leaving a portion available for connection to the needle. A curved needle having a cutting tapered point is swaged to the free end of the single strand. Initially the wire is passed around the split sternum and the needle then removed with a pair of diagonal cutting pliers. A twisting tool, having a handle and a hooked portion, passes through the two free loops on opposite sides of the sternum. Twisting force is applied to the tool and transmitted through the hook to the suture causing it to twist and cable. The suture reaches its critical length L.sub.crit when the loop is fully cabled but before double cabling begins. At the onset of double cabling the loop reaches its maximum tension T.sub.crit.

  • Patent number: 5824010
    Abstract: A suture needle guide and a method of use therefor. A suture needle guide comprises a needle guide member connected to a manually-graspable handle. The needle guide member is inserted, via an arteriotomy, into the lumen of a host blood vessel. The needle guide member includes a portion which is shaped to guide a suture needle so that anastomosis can be more accurately and easily performed, compared to free-handed suturing.
