BACKGROUND Major liver trauma has a high mortality because of immediate exsanguination and a delayed morbidity from septicemia, peritonitis, biliary fistulae, and delayed secondary hemorrhage. We evaluated laser soldering using liquid albumin for welding liver injuries. METHODS Fourteen lacerations (6 x 2 cm) and 13 nonanatomic resection injuries (raw surface, 8 x 2 cm) were repaired. An 805-...

BACKGROUND AND OBJECTIVES Collagen solder is capable of fixation of surgical meshes during laparoscopic herniorrhaphy without compromising tissue integration, increasing adhesions or inflammation. This pilot study describes development of instrumentation and techniques for transabdominal preperitoneal (TAPP) herniorrhaphy using laser-assisted soldering technology. METHODS Anesthetized 20-kg t...

We investigate the effects of assembly process and its parameters on optical polarization in InP pump lasers for telecommunications. Different measurements were performed this study, such as degree laser emission below above threshold current, well evaluation induced strain materials by measuring linear photo-luminescence. demonstrate that soldering can affect both current.

The following application note represents a general guideline for mounting LEDs of the Golden DRAGON with Lens product family. A basic overview of the construction of LEDs and important design rules for the development of LED systems are provided. In addition, the principal processing steps are illustrated for the Golden DRAGON ARGUS LED, and general information about mounting is summarized. In...

The deposition of nano-size copper particles was carried out by means of ink-jet printing on the ceramic substrate (silicon and faience) using Nd +3 :YAG laser. Glycerin and aqueous based nano copper inks were prepared and were inkjetted in this study. The sintered copper film had a grainy structure with neck-like junctions. The microstructure and soldering properties were examined using XRD, S...

BACKGROUND AND OBJECTIVE Animal studies using open surgical models indicate that collagen solder is capable of fixation of surgical meshes without interfering with tissue integration, increasing adhesions, or increasing inflammation intraperitoneally. This study describes development of instrumentation and techniques for laparoscopic herniorrhaphy using laser-assisted soldering technology. ST...

Precision components or sensors exposed to corrosive conditions, or required to have extreme performance characteristics, are sealed hermetically into special packages. Epoxy glueing, resistance welding, soldering, electron-beam welding, and laser welding are several of the techniques available for sealing these packages. The disadvantage in the use of epoxies is that they do not create a herme...

BACKGROUND AND OBJECTIVES In this in vitro feasibility study we analyzed tissue fusion using bovine serum albumin (BSA) and Indocyanine green (ICG) doped polycaprolactone (PCL) scaffolds in combination with a diode laser as energy source while focusing on the influence of irradiation power and albumin concentration on the resulting tensile strength and induced tissue damage. MATERIALS AND MET...
