Preparation of human albumin solder for laser tissue welding

Lasers in Surgery and Medicine, 1993
AbstractPrevious studies have demonstrated that the addition of a protein solder to augment the laser tissue weld significantly improves postoperative results. Herein we describe a method for the preparation of human albumin for use as a laser tissue solder. We also review the brief history of laser tissue solders and discuss recent advances using this

Nanocomposite solder for laser welding of biological tissues

Semiconductors, 2011
The properties of biosolders for the laser welding of tissues are studied. High thermal- and photostability of solder compositions based on aqueous dispersions of albumin with single- and multilayer carbon nanotubes is demonstrated. As biological tissue samples, in vitro bovine trachea cartilage and pig skin are studied. The use of nanobiosolders makes

Impact of solubility on laser tissue-welding with albumin solid solders

Lasers in Surgery and Medicine, 2000
The correlation between the solubility of solid albumin solders and their laser weld strength was investigated.Sections of dog intestine were laser welded with soluble or insoluble solid strips of solder. Two different treatments were followed for tissue soldering: "wet weld" and "dry weld." These treatments were chosen to assess the impact of ...

Albumin-genipin solder for laser tissue welding

SPIE Proceedings, 2004
Background. Laser tissue soldering (LTS) is an alternative technique to suturing for tissue repair. One of the major drawbacks of LTS is the weak tensile strength of the solder welds when compared to sutures. In this study, the possibility was investigated for a low cytotoxic crosslinker, acting on amino groups, to enhance the bond strength of albumin ...

Results of Laser Tissue Soldering in Vasovasostomy and Epididymovasostomy

The Journal of Urology, 1997
The use of microsurgical techniques (vasovasostomy and epididymovasostomy) for vasectomy reversal has now enabled surgeons to perform both procedures with certainly acceptable success rates. However, these operations are technically demanding and require special training in microsurgery.A new method of performing these procedures using laser tissue ...

Laser soldering for laparoscopic bonding of tissues in pigs

SPIE Proceedings, 2003
Introduction: Laparoscopic pyeloplasty is used for the repair of uretero-pelvic junction (UPJ) obstructions. Our aim was to do it using laser tissue soldering. Materials and Methods: We developed a tissue bonding system based on a CO 2 laser, a temperature detector and infrared transmitting optical fibers, to obtain temperature controlled laser ...

Laser tissue soldering in urinary tract reconstruction: First human experience

Urology, 1995
Laser tissue soldering (LTS) in the urinary tract provides an immediate leak-free seal and may avoid complications seen with conventional repair (such as fistula and stricture). We have begun a Phase I clinical trial investigating the use of LTS in performing urologic reconstructive surgery.Ten patients (aged 3 months to 38 years) underwent urologic ...

Dye-Enhanced Protein Solders and Patches in Laser-Assisted Tissue Welding

Journal of Clinical Laser Medicine & Surgery, 1997
This study examines the use of dye-enhanced protein bonding agents in 805 nm diode laser-assisted tissue welding. A comparison of an albumin liquid solder and collagen solid-matrix patches used to repair arteriotomies in an in vitro porcine model is presented.Extrinsic bonding media in the form of solders and patches have been used to enhance the ...

Novel solid protein solder designs for laser-assisted tissue repair

Lasers in Surgery and Medicine, 2000
Previous studies have shown that the application of chromophore-enhanced albumin protein solders to augment laser tissue repairs significantly improves repair strength, enhances edge co-optation, and reduces thermal tissue injury. These investigations are furthered with this in vitro study conducted to assess a new range of specially designed ...
