Intended Use

The Trimedyne Holmium:YAG Laser System is indicated for superficial incision. excision, resection, ablation, coagulation, hemostasis, and vaporization, with or without an endoscope, in multispecialty applications. When used in conjunction with the Trimedyne Side Firing Needle with Vent Sheath family of optical fiber delivery devices, these laser systems may be used for interstitial incision, excision, resection, ablation, coagulation, hemostasis, and vaporization in multispecialty applications.

Device Story

Trimedyne Holmium Laser System is a Class IV, pulsed, solid-state Holmium:YAG laser; delivers infrared energy at 2.1 µm wavelength with 350 µs pulsewidth. System includes models 1210, 1210-VHP, 1230-30, and 1500-A. Operated by clinicians in clinical/surgical settings; uses menu-driven controls to adjust pulse repetition rate, output energy, and duration. Laser energy delivered via optical fibers (including Side Firing Needle with Vent Sheath for interstitial use) to target tissues for surgical procedures. Output allows for precise tissue interaction (incision, ablation, hemostasis). Benefits include minimally invasive surgical access and effective tissue management across multiple specialties.

Clinical Evidence

No clinical data or non-clinical testing data were submitted in this Premarket Notification.

Technological Characteristics

Holmium:YAG laser; 2.1 µm wavelength; 350 µs pulsewidth; maximum output 100 watts. Class IV laser-powered instrument. Menu-driven control interface for pulse repetition, energy, and duration. Standalone system. Sterilization requirements for delivery fibers apply.

Indications for Use

Indicated for superficial and interstitial incision, excision, resection, ablation, coagulation, hemostasis, and vaporization in dermatology, plastic surgery, gastroenterology, general surgery, urology, gynecology, lithotripsy, orthopedics, ENT, and percutaneous disc decompression. Patient populations include those with soft, mucosal, fatty, cartilaginous, or bony tissue conditions, including tumors, lesions, calculi, BPH, and herniated discs. Contraindications not explicitly listed, though specific clinical criteria (e.g., 12 weeks conservative therapy) apply to disc decompression.

Regulatory Classification

Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.
