example 1

[0286] 2 mm (80 mil) thick 3M VHB tape 4918 (3M VHB tape 4918) clear acrylic bonding adhesive laminated to 3M IOBAN 2 Antimicrobial Incise Drape (3M IOBAN 2 Antimicrobial Incise Drape) (3M Company ( St. Paul, MN)) on the back. A wedge-shaped piece of 3M VIKUITI Enhanced Specular Reflector (ESR) film consisting of a series of 3M VIKUITI Enhanced Specular Reflector (ESR) films that were wired to a 12 volt DC power supply was attached to the edge of the 2mm thick PSA side-emitting LED lights. The top surface of the thick PSA lightguide was covered with a 50 micron (1.95 mil) thick layer of clear biaxially oriented polypropylene (BOPP) film (prepared as described in PCT Publication No. WO 2010 / 021796). When powered on, light enters the 2mm (80 mil) thick PSA and can be seen exiting the open end of the light guide (the LED only shoots into one edge). When the BOPP / PSA / Ioban sandwich laminate was cut using a razor knife, it was evident that light was emitted from the freshly cut s...

example 2

[0288] 1 mm (40 mil) of 3M VHB tape 4910 (3M VHB tape 4910) clear acrylic bonding adhesive was laminated to the back of the 3M IOBAN 2 Antimicrobial Incise Drape. A wedge-shaped piece of 3M ESR film containing a series of side-emitting LED lights wired to a 12 volt DC power supply was attached to the edge of the 1 mm thick PSA. The top surface of the thick PSA lightguide was covered with a layer of clear BOPP. When powered on, light enters the 1 mm thick PSA and can be seen exiting the open end of the light guide (LEDs only shooting into one edge). When the BOPP / PSA / Ioban sandwich laminate was cut using a razor knife, it was evident that light was emitted from the freshly cut surface.

example 3

[0290] LEDs can be packaged in polycarbonate or poly(methyl methacrylate) (PMMA) transparent / translucent rigid, solid shapes with molded-in pointed "needles." The packaged LEDs (using industry standard clips on electrical connectors such as those used in 3M RED DOT electrode products) can simply be "pushed" into the thick lightguide PSA layer at any desired point to pass through the PSA Light guides the drape site to provide custom lighting. This example is in Figure 9 shown in .

Abstract

Methods and products for illuminating the tissue of a patient wherein the products include a conformable polymeric layer.

Description

[0001] Related Patent Applications [0002] This patent application claims priority to US Provisional Patent Application Serial No. 61 / 236,027, filed August 21, 2009, which is incorporated herein by reference in its entirety. Background technique [0003] Surgical incise drapes are adhesive-coated organic polymer drapes that are applied to the skin of a patient, typically after application of a preoperative preparation. The physician makes the incision just through the drape. In this way, on the skin surface and incision site, the drapes physically limit the migration of bacteria remaining after the surgical preparation steps. The incision drapes provide the surgeon with a sterile surface adjacent to the wound. Additionally, the Incision Drapes can be used to securely hold other Drapes on the patient. Surgical incise drapes used during such surgeries have been designed to be very thin and conformable with high adhesion to the skin in order to allow the surgical skin to Do...
