Photothermal effects of laser tissue soldering

Physics in Medicine and Biology, 1999
Low-strength anastomoses and thermal damage of tissue are major concerns in laser tissue welding techniques where laser energy is used to induce thermal changes in the molecular structure of the tissues being joined, hence allowing them to bond together.

Two-wavelength approach for control of coagulation depth during laser tissue soldering

Proceedings of SPIE, 2015
Paper 932109In laser tissue soldering (LTS) protein solutions are used for closing of incisions or fixation of wound dressings. During coagulation and thermal denaturation of the protein solutions their morphology changes significantly such that light is

Albumin–genipin solder for laser tissue repair

Lasers in Surgery and Medicine, 2004
AbstractBackgroundLaser tissue soldering (LTS) is an alternative technique to suturing for tissue repair that avoids foreign body reaction and provides immediate sealing of the wound. One of the major drawbacks of LTS, however, is the weak tensile strength of the solder welds when compared to sutures.

Laser tissue soldering: Applications in the genitourinary system

Current Urology Reports, 2003
Within the past 25 years, lasers have transitioned from merely destructive or ablative tools to those with reconstructive uses. It has been shown that the application of laser thermal energy to tissue will result in welding of the approximated areas.

Optimal solder and power density for diode laser tissue soldering (LTS)

Lasers in Surgery and Medicine, 2001
AbstractBackground and ObjectiveLaser tissue soldering (LTS) using albumin and indocyanine green dye (ICG) is an effective technique utilized in various reconstructive surgical procedures. The purpose of this study was to describe in vivo and in vitro temperature profiles of an albumin‐based solder while varying ICG concentration and laser power ...

Free-electron laser tissue-soldering in vitro with an albumin solder

SPIE Proceedings, 2000
The purpose of this study was to explore the feasibility of using a free-electron laser (FEL) to photothermally coagulate an albumin solder for laser-assisted incision closure. A 50%(w/v) bovine serum albumin solder was used to repair an incision in bovine aorta.

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 ...

Temperature‐controlled two‐wavelength laser soldering of tissues

Lasers in Surgery and Medicine, 2011
AbstractBackground and ObjectiveLaser tissue soldering is a method for bonding of incisions in tissues. A biological solder is spread over the cut, laser radiation heats the solder and the underlying cut edges and the incision is bonded. This method offers many advantages over conventional techniques (e.g., sutures).

Novel laser tissue-soldering technique for dural reconstruction

Journal of Neurosurgery, 2005
Object The goal of this study was to use a modified version of the CO2 laser—soldering system to develop a simple and reliable technique for the repair of dural defects after excision of brain tumors. Methods The authors used a CO2 fiber optic laser system that they had developed for heating, monitoring, and controlling tissue temperature in situ ...

Sutureless Laparoscopic Heminephrectomy Using Laser Tissue Soldering

Journal of Endourology, 2003
Widespread application of laparoscopic partial nephrectomy has been limited by the lack of a reliable means of attaining hemostasis. We describe laser tissue welding using human albumin as a solder to control bleeding and seal the collecting system during laparoscopic heminephrectomy in a porcine model.Laparoscopic left lower-pole heminephrectomy was ...
