Novel laser tissue-soldering technique for dural reconstruction

Abstract

Fascia-dura mater soldering using the CO2 laser is feasible and may support CSF pressure up to six times higher than normal intracranial pressure. Findings of this study may provide a basis for the development of new tools for dural reconstruction.

Measuring tissue heat penetration by scattered light measurements

“…Other thermal interaction applications are tissue welding [7] and soldering [8,9]. The parameters that affect the thermal interaction were investigated by several researchers.…”

Corneal cut closure using temperature-controlled CO2 laser soldering system

“…In addition, sutures pose a risk of complications, including infection [1], induced astigmatism [2], erosion [3], foreign body sensation, irritation of the cornea and conjunctiva from exposed knots and corneal edema, neovascularization [4], and leakage [5]. Soldering techniques have been studied for more than 30 years [6,7] as an alternative to sutures for tissue bonding [8][9][10][11][12], including sclero-corneal and corneal cuts [13,14]. Pini et al [14] were the first to apply laser welding in clinical transplantation of the cornea over a decade ago.…”

“…The material is applied to the approximated edges of the surgical cut, and the laser beam heats the solder and the underlying cut edges [9,11]. Several experimental studies have shown that laser soldering is efficient for bonding different types of tissues [8,10,[12][13][14], including the cornea [12,13].…”

New laser soldering-based closures: a promising method in natural orifice transluminal endoscopic surgery

“…It has been used on vascular tissue, in the urinary tract, and on cornea tissue. [21][22][23][24][25][26] Soldering creates an immediate watertight closure. LTS results in less inflammation with faster inflammatory recovery than suturing procedures.…”
