Intended Use

The CooperSurgical Infrared Coagulator ("IRC") is intended for coagulative necrosis of tissue. It is indicated for the treatment of genital condylomas (condyloma accuminata) and general warts.

Device Story

The CooperSurgical Infrared Coagulator (IRC) is a medical device used for coagulative necrosis of tissue. It consists of a control unit, handpiece, removable light guide, and disposable contact tip. The device delivers short pulses of visible and infrared light from a 15-volt halogen bulb. The physician applies the contact tip to the target tissue and triggers the device; a built-in digital timer automatically deactivates the lamp based on a preselected pulse duration. The depth of tissue necrosis is controlled by the pulse length. Used in a clinical setting by a physician, the device provides a thermal coagulation effect similar to surgical lasers. It is used to treat genital condylomas and general warts, offering a non-laser alternative for tissue destruction. The use of disposable tips with an integral sheath protects the light guide from tissue contact.

Clinical Evidence

Two clinical studies were provided demonstrating the IRC is equivalent to predicate laser devices for the treatment of genital condylomas and general warts.

Technological Characteristics

System components: control unit, handpiece, removable light guide, disposable contact tip. Energy source: 15-volt halogen bulb. Principle: contact photocoagulation via visible and infrared light pulses. Features: digital timer for pulse duration control, single-use sterile contact tips with integral sheath.

Indications for Use

Indicated for the treatment of genital condylomas (condyloma accuminata) and general warts in patients requiring tissue necrosis.

#### Name of the Device

CooperSurgical Infrared Coagulator

#### Common or Usual Name

#### Infrared Coagulator

#### Predicate Devices

- Redfield Corporation's Redfield Infrared Coagulator for the (1) treatment of hemorrhoids (K842810/A) and chronic rhinitis (K950836), and for tattoo removal (K911648).
- Laserscope's KTP/YAG Surgical Laser Systems (K913758) (2)
- Sharplan Lasers, Inc.'s Model 3100 Nd:YAG Surgical Laser (3) (K951165)
- Xanar Surgical Laser Systems' Xanar CO2 Surgical Laser System (4) Model XAP-15 (K861688).

#### Intended Use

The CooperSurgical Infrared Coagulator ("IRC") is intended for coagulative necrosis of tissue. It is indicated for the treatment of genital condylomas (condyloma accuminata) and general warts.

{1}------------------------------------------------

## Principles of Operation

The Cooper IRC delivers short pulses of visible and infrared light through a small contact tip applicator that is applied to the tissue. This light causes thermal coagulation that results in tissue necrosis. The user sets the pulse duration control knob depending on the depth of the tissue necrosis required. The depth of coagulation is directly related to the pulse length delivered to a given area of tissue. The area(s) to be treated may be locally anesthetized at the physician's discretion.

Contact photocoagulation requires direct contact of the entire optical window of the disposable contact tip. The physician applies light mechanical pressure to the optical window against the tissue to be treated before depressing the activation trigger of the hand piece. To achieve coagulation, the user depresses the activation trigger. A built-in digital timer deactivates the lamp automatically according to the pulse duration setting preselected by the physician. If the desired treatment site is larger than the optical window, the physician may use overlapping exposures until the entire lesion is coagulated, waiting at least five seconds between exposures.

### Technical Characteristics

The CooperSurgical IRC consists of the following main components: (1) a control unit; (2) a hand piece; (3) a removable light guide; and (4) a disposable contact tip. With the exception of two features, the CooperSurgical IRC is essentially the same device as Redfield Corporation's Infrared Coagulator that has already been cleared by FDA for the treatment of hemorrhoids (K842810/A) and chronic rhinitis (K950836), and for tattoo removal (K911648).

### Summary of the Basis for the Finding of Substantial Equivalence

The safety and effectiveness of the CooperSurgical IRC is based on: (1) Redfield IRC's premarket clearances for the treatment of hemorrhoids and chronic rhinitis, and for tattoo removal; (2) the long history of use of lasers for the treatment of genital condylomas and general warts; and (3) two recent clinical studies demonstrating that the IRC is equivalent to its predicate devices for the treatment of genital condylomas and general warts.

With the exception of two features, the CooperSurgical IRC is practically the same device as the Redfield IRC, which has already received premarket clearance for the treatment of hemorrhoids (K842810/A) and chronic rhinitis (K950836) and for tattoo removal (K911648). The primary differences between the devices are (1) the indications for use; (2) the inclusion of single use/sterile (as opposed to reusable) contact tips with an integral sheath to protect the light guide from tissue contact; and (3) the use of a different 15 volt halogen bulb.

{2}------------------------------------------------

In addition, the CooperSurgical IRC is substantially equivalent to several lasers that have received premarket clearance for genital condylomas (condyloma accuminata) and general warts: Laserscope's KTP/YAG Surgical Laser Systems (K913758), Sharplan Lasers, Inc.'s Model 3100 Nd:YAG Surgical Laser (K951165) and Xanar Surgical Laser Systems' Xanar CO2 Surgical Laser System Model XAP-15 (K861688).
