Abstract: A golf swing alignment device that includes a housing having a laser, which can be directed at a target such as a golf hole to enable the golfer to pre-position his or her body and feet prior to striking the ball. An affixing device for affixing the housing to a location on a golfer's body such as a VELCRO® strap or belt clip is also provided. The laser emits a signal that points toward an external reference for providing the golfer with a swing alignment reference separate from the golfer's body. One or more laser devices can be placed at various positions on the golfer's body or clothing such as the ankle, belt or cap. The golfer can activate one or more of the laser devices by use of a remote control unit that sends power and command signals to the one or more laser devices. The remote control unit can also modify the laser signal to produce, for example, intermittent bursts of laser light in order to better define the path to the target.

Abstract: A catheter placement system designed to permit a physician to quickly and safely place a large gage catheter into a selected major vein, while avoiding injury to the selected vein, nerves or other veins located about the area of the insertion. Initially, a small finder needle is inserted into the area where selected vein is expected to be located to cause as little damage as possible to the surrounding tissue. Once blood is drawn easily through the finder needle, the selected vein has been located. The finder needle is placed coaxially within a support tube, which is placed coaxially within the catheter. The finder needle is used as a guide for the support tube and catheter, which are moved together over the finder needle into the selected vein, with the support tube providing needed support for the usually flexible catheter to make it rigid while progressing to the selected vein.
