“…According to various studies [59][60][61], the tissue remodeling process is characterized by the equilibrium between extracellular matrix (ECM) remodeling and collagen biosynthesis. This balance is achieved through the thermal response of three main biologic structures: matrix metalloproteinases (MMPs) [62,63], transforming growth factors (TGFs) [64,65], and heat-shock proteins (HSPs) [66,67]. When observing collagen biosynthesis, Nagata [67] and DeBruler et al [68] showed that HSP 47 is responsible for producing neocollagenesis that will benefit tissue remodeling.…”

Laser welding presents a core position in the health sector. This process has had an outstanding impact on the surgical procedures from many medical areas, such as on vascular and nervous surgeries. The aim of the present research is to present an overview on the evolution of laser welding of vascular and nervous tissues. These surgeries present many advantages, such as an absence of foreign-body reactions and aneurysms and good tensile strengths. However, despite the sutureless nature of the process, complementary sutures have been applied to support the procedure success. An important concern in vascular and nervous laser welding is the thermal damage. The development of temperature-controlled feedback systems has reduced this concern with a very precise control of the laser parameters. The bonding strength of vascular and nerve laser welds can be enhanced with the application of solder solutions, bonding materials, and laser-activated dyes. Alternative techniques to laser welding, such as photochemical tissue bonding and electrosurgical high-frequency technologies, have also been tested for vascular and nervous repairs.
