OmniGuide Holdings Completes Merger of OmniGuide & Domain Surgical

omniguide-domain-mergerLexington, MA – August 10, 2016 – OmniGuide Holdings, Inc., the parent company of OmniGuide, Inc., a leader in flexible fiber CO2 laser surgery, announced today that it has signed an agreement to merge with Domain Surgical Inc., to enhance its advanced energy surgical portfolio.

The merger with Domain Surgical, Inc., Salt Lake City, UT broadens the ability to bring safe and precise surgical technologies to more surgeons and patients.  Domain Surgical is the maker of the FMX Ferromagnetic Surgical System, a surgical platform that uses ferromagnetic technology to precisely and safely cut, coagulate and seal tissue; with minimal injury to surrounding tissue as compared to other surgical technologies.

Despite advances in technology, surgical interventions can cause undesired collateral damage to healthy tissue, which can lead to post-operative pain, prolonged patient recovery and complications.  Domain Surgical’s patented ferromagnetic technology is based on the principle of ferromagnetic heating.  Simply described, heat is produced when a material having magnetic “domains” is exposed to an alternating magnetic field. The result is a surgical system that provides consistent cutting and hemostasis, with much less thermal injury than traditional electrosurgery, without passing potentially dangerous electrical current through the patient.

OmniGuide’s combined technologies now deliver a variety of surgical applications, to ENT and GYN surgeons, ranging from precision cutting and ablation, to quick hemostatic dissection, to reliable vessel sealing; all with optimized precision and safety, without passing electrical current through the patient.

In conjunction with the merger, John T. Buhler, has been named President and CEO of OmniGuide Holdings.  Mr. Buhler has extensive experience in the technology, life-sciences and healthcare fields with a career spanning 30+ years. He has been the CEO/COO of three public and two private companies, completed numerous rounds of financing, done ~$1 billion in mergers and acquisitions, and most recently merged RF Surgical Systems, Inc. with Medtronic. He has successfully completed four turnarounds, with each entity becoming a high growth/profitable business in its discipline. Mr. Buhler has an impressive history generating new revenue streams, building business, and increasing market share for multi-million and multi-billion dollar international high-technology corporations. His businesses have demonstrated the ability to penetrate new markets and strengthen competitive positioning, design and direct high-impact strategic plans, define visions and transform concepts into lucrative workable realities.

“Both OmniGuide and Domain Surgical technologies are known for extreme precision and for minimizing unintended collateral damage to healthy tissue during complex surgical procedures. Further, both technologies are designed to increase patient safety and improve clinical outcomes,” said Mr. Buhler. “Merging the companies provides an expanded advanced energy product portfolio that delivers precise cutting, ablation, dissection, and vessel sealing capabilities across numerous sub-specialties. I am excited to be a part of this dynamic team as we grow the company moving forward.”

Nimble Laser Devices for Minimally Invasive Gynecologic Surgery

Here is an except from a recent article in Contemporary OB-GYN. Please click here to read this article in it’s entirety.

“In our clinical practices, we use the CO2 laser delivered by flexible fiber in myomectomy, lysis of adhesions, and treatment of endometriosis. We find that it functions extremely well in all these situations, thanks to its specific maneuverability, functionality, and safety profiles, especially in conjunction with the minimal depth of penetration of thermal damage. This provides increased safety while working near critical structures such s bowel, bladder, ureters, and blood vessels.”

TORS-L Eliminates Adjuvant Therapies In An Oropharyngeal Cancer Patient

With a diagnosis of stage 2 squamous cell carcinoma of the tonsil, Tony Lentola might have expected a treatment plan that included the traditional six weeks of radiation – and possibly chemotherapy.  Thanks to a referral to Ron Karni, MD, who routinely does surgery for oropharyngeal cancers using transoral robotic surgery with a CO2 laser (TORS-L), Lentola avoided the toxic treatments, the effects of which are particularly pronounced in head and neck cancer patients.

RK by-lineLentola is one among many patients at UTHealth and Memorial Hermann-Texas Medical Center to benefit from the coupling of the da Vinci robot to the flexible CO2 fiber, which can be used to precisely resect tumor margins.  Diagnosed in November 2013, the 64-year-old underwent surgery with TORS-L following a biopsy that confirmed the malignancy.  “We’ve found that combining transoral robotic surgery with a CO2 laser allows for greater precision, a better chance of cancer cure and elimination or de-intensification of adjuvant therapies in cases of early diagnosis,” says Dr. Karni, an assistant professor in the Department of Otorhinolaryngology-Head and Neck Surgery at UTHealth Medical School, who focuses his practice on head and neck oncologic surgery and diseases of the thyroid and parathyroid.  “The toxicity of these treatments in oropharyngeal cancer patients is well-documented, and many of the effects are lifelong. By avoiding them, we improve functional outcomes.”

Laser Safety Training Video for GYN (Surgeon Narrated)

Amelia Bailey, MD, Director of Minimally Invasive Surgery at Fertility Associates of Memphis, recently helped OmniGuide Surgical design a video overview for laser safety in the operating room. Dr. Bailey explains how “it is important to recognize that not all lasers are created the same” and details how CO2 laser can be ideal for surgery because it is highly absorbed in water and tissue so energy is halted near the surface. In addition to explaining the properties of different laser wave lengths, she also goes over proper safety protocols and best practices for using the OmniGuide CO2 laser system in the OR.


With over 100,000 surgeries completed, OmniGuide has pioneered and lead the way for flexible CO2 laser use in today’s operating room and is redefining the energy for minimally invasive surgery. For more information or to request a demo of our technology please contact OmniGuide Surgical here.

Surgeon Narrates Video of Vocal Cord Dysplasia Case with ELEVATE ENT System

M. Boyd Gillespie, MD, an otolaryngologist-head and neck surgeon at the Medical University of South Carolina, recently had a Vocal Cord Dysplasia case with a 39-year-old male patient who had a history of early vocal cord cancer. Following radiation, he had persistent dysplastic tissue on the surfaces of his vocal cords that showed poor mobility on stroboscopic examination. As explained by Dr. Gillespie in the narrated surgical video below, “Given the large size of the dysplasia a simple biopsy may miss sites of cancer, therefore, in this case, we are using the laser fiber to perform a complete vocal cord stripping so that the entire surface of the vocal cord can be analyzed by the pathologist.”

The surgeon chose to perform the case using the ELEVATE™ ENT System, OmniGuide Surgical’s next-generation flexible CO2 laser fiber system designed specifically for head and neck and airway surgery. Of the minimally invasive technology Gillespie explains, “The Elevate tip allows palpation of the underlying vocal ligament while the laser fiber works in a bloodless plane to lift the dysplastic tissue off the vocal fold.”

With over 100,000 surgeries completed, OmniGuide has pioneered and lead the way for flexible CO2 laser use in today’s operating room and is redefining the energy for minimally invasive surgery. For more information or to request a demo on the ELEVATE ENT System please contact OmniGuide Surgical here.
