Experimental Evaluation of Pulse 1550 Nm Laser System for Welding of Heart Tissue

Abstract

Laser tissue welding (LTW) uses laser energy to anastomose tissues and is ideally suited for applications in which suturing and stapling is difficult. The advantages of LTW compared with traditional methods of wound closure are the absence of foreign body reaction and less scar formation. The objective of this study was to determine whether a dissected heart walls could be welded by 1550 nm laser using an in vitro chicken hearts dissection model.
