Abstract: A method of embossing a sheet material includes: heating at least a portion of the sheet directly or indirectly with radiant energy from a radiant energy source; pressing a tool against the heated portion of the sheet, thereby patterning a surface of the sheet; and separating the sheet and the tool. The radiant energy may travel through a solid material that is relatively transparent to radiation, on its way to being absorbed by a relatively-absorptive material. The relatively-transparent material may be an unheated portion of the sheet, and the relatively-absorptive material may be either the tool or the heated portion of the sheet. Alternatively, the relatively-transparent material may be the tool, and the relatively-absorptive material may be all or part of the sheet. The method may be performed as one or more roll-to-roll operations.

Abstract: An illuminated intraocular surgical instrument having a grip and a tubular member supported by the grip and extending outwardly from its first end. A surgical tool has a shaft extending from within the tubular member outwardly from the distal end of the member to a free end. The shaft of the tool extends generally along the longitudinal axis of the tubular member as it exits the member through its open distal end. A plurality of light conducting fibers extending through the tubular member have terminal ends located generally at the distal end of the member. The light fibers are arranged at the open distal end of the tubular member generally around the shaft of the tool within the tubular member to illuminate the portion of the surgical tool disposed outwardly of the distal end of the tubular member and the area of operation, and to inhibit the casting of shadows by the surgical tool in the area of operation.

Abstract: A phacoemulsification transducer or probe utilizing ultrasonic frequencies to treat cataracts, including a rotatable handle to facilitate repositioning of the needle in the eye during surgery while maintaining a comfortable and secure grip on the instrument. The rotatable handle is comprised of a sleeve portion, irrigation tube and connector member. The sleeve portion is secured to the front of the main body of the probe and the connector member is attached to the distal end thereof.
