Device Story

OmniPulse™ Mini Model 2120 is a pulsed solid-state Ho:YAG laser system; delivers infrared laser energy at 2.1 µm wavelength. Input: operator-selected pulse energy (0.2–2.0 J), frequency (7, 10, 15, 20 Hz), and exposure mode (continuous, single burst, repetitive burst). Operation: flash lamp-driven; emits pulses consisting of overlapping spikes (nominal duration 350 µs). Output: laser radiation for surgical tissue interaction. Used in OR or clinical settings by physicians (surgeons, urologists, etc.) for incision, ablation, and hemostasis. Output allows precise tissue removal or coagulation; benefits include minimally invasive surgical options and reduced bleeding. System is compatible with Trimedyne arthroscopic handpieces and optical fiber delivery devices.

Clinical Evidence

No clinical data was submitted in this Premarket Notification.

|-----------------|-------------------------------------------------------|
| Common: | Holmium:Yttrium Aluminum Garnet (Ho:YAG) Laser System |
| Classification: | Various Medical Lasers |

#### lll. Predicate Device

The predicate devices for the OmniPulse™ Mini are the Trimedyne OmniPulse™-MAX and OmniPulse Jr.™ laser systems.

## IV. Device Description

The OmniPulse" Mini Laser System Model 2120 is a pulsed solid-state Holmium:YAG laser system is designed to deliver infrared laser energy with a wavelength of 2.1 um and a nominal pulse width of 350 microseconds. Menu driven control options allow the operator to select the pulse energy, the pulse repetition rate or frequency, and one of three exposure modes (continuous, single burst or repetitive burst).

## V. Intended Use

The OmniPulse™ Mini is designed for use in conjunction with Trimedyne's various arthroscopic handpieces and optical fiber delivery devices. As with the other cleared Trimedyne Ho:YAG laser systems, applications for this laser system include superficial incision, excision, resection, ablation, coagulation, hemostasis, and vaporization, with or without an endoscope, in the following indications:

. "

- General Surgery of Soft Tissues .
- . Genitourinary Surgery/Urology
- . Otorhinolanryngology (ENT) Surgery
- Gynecological Surgery .
- Lithotripsy and Percutaneous Urinary Lithotripsy ◆

- Orthopedic Surgery .
- Percutaneous Cervical, Lumbar, and Thoracic Disc Decompression/Discectomy

2/2

- Therapeutic Dermatological, Therapeutic Plastic, and Aesthetic Surgical . Procedures
- Gastroenterological/Gastrointestinal Surgery .

When used in conjunction with the Trimedyne Side Firing Needle with Vent Sheath family of optical fiber delivery devices, this laser system may be used for interstitial incision, excision, resection, ablation, coagulation, hemostasis, and vaporization in multispecialty applications.

## VI. Technological Characteristics

The laser is driven by a flash lamp and emits one pulse of laser radiation each time the flash lamp is fired. The laser pulse refers to the pulse waveform - each laser pulse consists of large numbers of overlapping spikes that have a duration of about one microsecond. These spikes compose the pulse waveform with nominal pulse duration of 350 microseconds. Laser pulses are generated at the frequency chosen by the operator. Pulse frequencies of 7, 10, 15 and 20 Hz are available.

In general, the operator may request pulse energies from 0.2 to 2.0 Joules. The range of pulse energies available depends on the pulse frequency. Not all energies are available at all pulse frequencies. The number of pulses emitted from the laser system can be controlled by the operator through the choice of one of three exposure modes.

## VII. Nonclinical Data

No nonclinical data was submitted in this Premarket Notification.

## VIII. Clinical Data

No clinical data was submitted in this Premarket Notification.

## . IX. Conclusions

All of the characteristics of the OmniPulse Mini fall with the previously cleared ranges for the predicate devices. Therefore, the OmniPulse Mini Model 2120 is substantially equivalent to the Trimedyne OmniPulse™-MAX and OmniPulse Jr. ™ laser systems.
