Nanoshell assisted laser soldering of vascular tissue
Lasers in Surgery and Medicine, 2011 AbstractBackground and ObjectivesLaser tissue soldering (LTS) is a promising technique for tissue fusion but is limited by the lack of reproducibility particularly when the amount of indocyanine green (ICG) applied as energy absorber cannot be controlled during the soldering procedure. Nanotechnology enables the control over the quantitative binding of

Thermal model for optimization of vascular laser tissue soldering
Journal of Biophotonics, 2010 AbstractLaser tissue soldering (LTS) is a promising technique for tissue fusion based on a heat‐denaturation process of proteins. Thermal damage of the fused tissue during the laser procedure has always been an important and challenging problem. Particularly in LTS of arterial blood vessels strong heating of the endothelium should be avoided to ...

Microsurgical anastomosis of sperm duct by laser tissue soldering
SPIE Proceedings, 2005 Connection of small vessels is usually done by suturing which is very cumbersome. Laser tissue soldering can circumvent that obstacle if a handy procedure can be defined. Our principle approach consists of a bioresorbable hollow stent with an expected degradation time of 3 weeks in combination with laser soldering.

Commentary: Photothermal effects of laser tissue soldering
Physics in Medicine and Biology, 1999 Laser tissue welding is the process of using laser energy to join tissues without sutures or with a reduced number of sutures. Recently, diode lasers have been added to the list of fusion lasers (Lewis and Uribe 1993, Reali et al 1993). Typically, for tissue welding, deep penetrating diode lasers emitting at 800-810 nm are used, in combination with a ...

Investigation of Nanoparticle-Assisted Laser Tissue Soldering by Terahertz Radiation
2019 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2019Laser tissue soldering is an attractive approach for surgical repair. The principle is to use laser light in combination with a solder solution, such as albumin, to ‘stitch’ wound openings together. The soldering process can be enhanced by combining albumin with plasmonic nanoparticles, which act as localized absorbers that effectively transfer the ...

Laser tissue soldering with near-infrared absorbing nanoparticles
SPIE Proceedings, 2005Gold nanoshells are a new class of nanoparticles with tunable optical absorption that can be placed in the near infrared. Gold nanoshells consist of a spherical silica core surrounded by a thin gold shell. The ratio of the sizes of the core diameter to the shell thickness as well as the total size of the nanoshell determines the optical absorption ...

An in-vitro investigation of skin tissue soldering using gold nanoshells and diode laser
Lasers in Medical Science, 2010Gold-coated silica core nanoparticles have an optical response dictated by the plasmon resonance (PR). The wavelength at which the resonance occurs depends on the core and shell size, allowing nanoshells to be tailored for particular applications.
