Intended Use

The HALO® ULTRA Ablation Catheter (used with the HALOffer Energy Generator, model 1190A-115A) is indicated for use in the coagulation of bleeding and non-bleeding sites in the gastrointestinal tract including but not limited to the esophagus. Indications include Esophageal Ulcers, Mallory-Weiss tears, Arteriovenous Malformations, Angiomata, Barrett's Esophagus, Dieulafoy Lesions, Angiodysplasia, Gastric Antral Vascular Ectasia (GAVE) and Radiation Proctitis (RP).

Device Story

Sterile, single-use bipolar electrosurgical catheter; delivers RF energy to GI tissue via copper electrode. Used with HALOFEX Energy Generator (model 1190A-115A). Introduced into esophagus under endoscopic visualization; physician positions electrode against target tissue by deflecting endoscope. Generator recognizes catheter via unique ID in plug; sets power/energy density. Energy activation via generator front panel switch or foot-pedal. Coagulation effect verified endoscopically. Benefits include controlled tissue coagulation for various GI lesions/vascular conditions.

Clinical Evidence

Bench testing only. Evaluated migration, deflection, catheter distal integrity, and detachment to confirm substantial equivalence following minor component dimension changes.

Technological Characteristics

Bipolar electrosurgical catheter; copper electrode; RF energy source. Single-use. Connects to external energy generator. Dimensions modified for pivot mechanism; manufacturing process change for endoscope mounting strap. Sterile.

Indications for Use

Indicated for coagulation of bleeding and non-bleeding GI tract sites, including esophagus. Conditions include esophageal ulcers, Mallory-Weiss tears, AVMs, angiomata, Barrett's esophagus, Dieulafoy lesions, angiodysplasia, GAVE, and radiation proctitis.

Regulatory Classification

Identification

An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current.

## COMMON OR USUAL NAME

Electrosurgical Coagulation Catheter

### REGULATION DESCRIPTION

Electrosurgical Cutting and Coagulation Devices and Accessories (21 CFR 878.4400, Product Code GEI)

### PREDICATE DEVICE

Primary predicate device:

- HALO® ULTRA Ablation Catheter (model 90-9200, cleared under K101111), . hereafter referred to as "original ULTRA".
Secondary predicate device:

- HALO® Ablation Catheter (model 90-9300, cleared under K112545), hereafter . referred to as "HALO60".
#### DEVICE DESCRIPTION

The subject device, HALO® ULTRA Ablation Catheter (hereafter referred to as "modified ULTRA") is a sterile single-use bipolar device that delivers radiofrequency (RF) energy to the treatment tissue within the gastrointestinal tract through a copper electrode. It is used exclusively with HALOFES Energy Generator model 1190A-115A (cleared under K092487).

K120431

## TECHNOLOGICAL CHARACTERISTICS

The modified ULTRA is a modification of the original ULTRA. Both catheters have the same construction, principles of operation, materials and energy density. The differences between the modified ULTRA and the original ULTRA include a slight change in the manufacturing process of the endoscope mounting strap, as well as dimensional modification on the pivot mechanism components.

## PRINCIPLES OF OPERATION

Same as the original ULTRA and HALO®, the modified ULTRA is connected to the HALOFEX Energy Generator using an output cable. Once connected, the Generator will recognize the catheter based on a unique ID in the plug and set the appropriate power density and energy density range.

The modified ULTRA is introduced into the esophagus under endoscopic visualization. Once the targeted treatment area is identified, the catheter electrode is positioned against the tissue by deflecting the endoscope. The energy activation is performed by depressing either a front panel switch on the generator or the foot-pedal. After the energy is delivered, the coagulation effect can be verified endoscopically.

## INDICATION FOR USE STATEMENT

The HALO® ULTRA Ablation Catheter (used with the HALOffer Energy Generator, model 1190A-115A) is indicated for use in the coagulation of bleeding and non-bleeding sites in the gastrointestinal tract including but not limited to the esophagus. Indications include Esophageal Ulcers, Mallory-Weiss tears, Arteriovenous Malformations, Angiomata, Barrett's Esophagus, Dieulafoy Lesions, Angiodysplasia, Gastric Antral Vascular Ectasia (GAVE) and Radiation Proctitis (RP).

#### SUBSTANTIAL EQUIVALENCE DISCUSSION AND CONCLUSION

The modified ULTRA and the predicate devices, the original ULTRA and HALO®, are identical in the intended use, principle of operations, energy type, materials, packaging and sterilization method. The minor differences in component dimension are evaluated via the following bench testing: (1) Migration; (2) Deflection; (3) Catheter Distal Integrity; (4) Detachment. No new questions of safety and effectiveness were raised. The subject and the predicate devices are substantially equivalent.
