Background and Objectives To demonstrate, in vivo, acute strength reinforcement benefits of polymer film patches. Study Design/Materials and Methods Full thickness incisions created in a dorsal skin flap of Sprague–Dawley rats were closed by laser‐tissue welding: albumin solder was topically applied to the incision on the dermal surface, and a poly(lactic‐co‐glycolic acid) (PLGA) polymer film placed on the solder as a patch (controls had no film). Breaking strength was tested acutely (15–20 minutes after sacrifice). Results The patched incisions were statistically stronger than the controls (ANOVA, P < 0.05). Conclusions Polymer film patches may be a viable method to increase acute breaking strengths of welds using topically applied solder. Lasers Surg. Med. 31:339–342, 2002. © 2002 Wiley‐Liss, Inc.
