The Resolution™ Hemostasis Clipping Device is indicated for clip placement within the gastrointestinal (GI) tract for the purpose of: 1. Endoscopic marking 2. Hemostasis for: Mucosal/sub-mucosal defects < 3 cm . Bleeding ulcers Arteries < 2 mm . Polyps < 1.5 cm in diameter ● Diverticula in the colon .

Anchoring to affix jejunal feeding tubes to the wall of the small bowel; and Anchoring to affix fully covered esophageal self-expanding metal stents to the wall of the esophagus 4. As a supplemental closure method of luminal perforations < 20 mm that can be treated conservatively

Device Story

Single-use endoscopic clipping device; consists of delivery system (handle/catheter) and stainless steel/cobalt chrome clip. Operated by physicians in clinical settings. Clip jaws open/close up to five times for lesion repositioning. Used for GI tract hemostasis, marking, anchoring of feeding tubes/stents, and closure of small perforations. Provides mechanical tissue approximation; aids in preventing stent migration and reducing post-polypectomy hemorrhage risk.

Clinical Evidence

Clinical evidence based on published literature. Study 1 (Vanbiervliet et al., 2012): Prospective comparative study of esophageal stent anchoring; stent migration significantly lower with clips (13%) vs. no clips (57%, p=0.003). Study 2 (Liaquat et al., 2013): Retrospective analysis of 524 lesions; non-clipped lesions 6 times more likely to have delayed bleeding (95% CI, 2.0-18.5; p=0.002). Prophylactic clipping reduced delayed bleeding rate to 2.5% vs. 9.7% in non-clipped group (p=0.006).

Technological Characteristics

Materials: thermoplastic elastomers, stainless steel, polyethylene, polyester, cobalt chrome, styrene. Working lengths: 155cm and 235cm. Mechanical actuation via delivery catheter. Sterilization: Ethylene Oxide. Complies with ISO 10993 (biocompatibility) and ISO 11135-1 (sterilization).

Indications for Use

Indicated for patients requiring endoscopic clip placement in the GI tract for marking, hemostasis (defects <3cm, bleeding ulcers, arteries <2mm, polyps <1.5cm, diverticula, prophylactic post-resection), anchoring (jejunal feeding tubes, esophageal stents), or closure of luminal perforations <20mm.

Regulatory Classification

Identification

#### 4. DEVICE DESCRIPTION:

The Resolution" Hemostasis Clipping Device is a sterile, single-use, endoscopic clipping device consisting of two main components: the delivery system and the clip.

The delivery system is made up of a handle and delivery catheter. The delivery system is constructed using thermoplastic elastomers, stainless steel, polyethylene, and polyester materials. The Resolution™ Hemostasis Clipping Device delivery system is offered in 155cm and 235cm working lengths.

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

The clip consists of a stainless steel capsule, and clip arms, a Cobalt Chrome Yoke, and a styrene tension breaker. The clip is deployed from the delivery system during use. The Resolution clip jaws are engineered such that they can be opened and closed up to five times, aiding in repositioning of the clip at the lesion site. Opening and closing capability may be limited by clinical circumstances and patient anatomy, among other factors.

There are no associated accessories included with this device.

# 5. INDICATIONS FOR USE:

#### COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE 6. PREDICATE DEVICE:

There are no differences in the technological characteristics between the proposed device and the predicate Resolution Hemostasis Clipping Device (K 122660). The purpose of this Traditional 510(k) is to request an expanded indication for the proposed Resolution™ Hemostasis Clipping Device. The physical device will remain unchanged from the predicate K122660, but the expanded indication requires a change to the product labeling. All other design specifications remain unchanged.

## 7. PERFORMANCE DATA:

#### Non-Clinical Testing:

No performance data was required for this submission. The proposed device meets the requirements of ISO 10993 *Biological Evaluation of Medical Devices - Part 1: Evaluation and Testing", ISO 11135-1 "Sterilization of Health Care products - Ethylene Oxide - Part 1: Requirements for Development. Validation, and Routine Control of Sterilization processes for Medical Devices", and ISO 10993-7 "Biological evaluation of medical devices - Part 7: ethylene oxide sterilization residuals", as the design and materials remain unchanged from that of the predict Resolution Hemostasis Clipping Device (K122660).

## Clinical Data:

Boston Scientific used published clinical results on the Resolution Hemostasis Clipping Devices used for clipping fully covered esophageal self-expanding metal stents; and delayed bleeding rates with prophylactic clipping.

Vanbiervliet G, Filippi J, Karimdjee BS, et al. "The role of clips in preventing migration of fully covered metallic esophageal stents: a pilot comparative study", Surg Endosc, 2012, 26: p. 53-59, prospectively compared SEMSs that were anchored (affixed) to the wall of the esophagus with the Resolution Clip device to non-clipped SEMSs. Statistical analysis via Fisher Exact test indicated that stent migration was significantly (p=0.003) less when Resolution Clips were used to anchor stents in place (13%) as compared to stents that were not anchored with clips (57%). Furthermore, there were no complications observed in either group.

The report by Liaquat, H, Rohn E, Rex DK, Gastrointest Endosc, 2013. 77(3): p. 401-407, entitled "Prophylactic clip closure reduces risk of delayed postpolypectomy hemorrhage: experience in 277 clipped large sessile or flat colorectal lesions and 247 control lesions", compared rates of delayed bleeding for non-clipped versus prophylactically clipped defects postpolypectomy. The clipped lesions were treated with the Resolution Clip and had a mean size of 31 mm (range 20-100 mm).

A multivariate analysis indicated that the lesions that were not clipped were 6 times more likely to have a delayed bleed (95% CI, 2.0-18.5; p=0.002) than a fully clipped lesion. Furthermore. lesions that were partially clipped were not significantly (p=0.17) more likely to have delayed bleeding compared with fully clipped lesion. A Fisher Exact test comparing prophylactically clipped, complete and partial, to non-clipped defects indicated that the rate of delayed bleeding in the Resolution Clip group, 2.5%, was statistically less than that of the non-clip group 9.7% (p=0.006).

The results indicate that prophylactic polypectomy site closure with Resolution Clips is associated with a reduced the risk of delayed post polypectomy hemorrhage. These results strongly support the safety and effectiveness of the prophylactic use of the Resolution Clip in reducing the risk of delayed bleeding.

{3}------------------------------------------------

The clinical results demonstrate that the Resolution Hemostasis Clipping Device can be safely and effectively used within the gastrointestinal (GI) tract for the purpose of hemostasis for prophylactic clipping to reduce the risk of delayed bleeding post lesion resection; and anchoring to affix fully covered esophageal self-expanding metal stents to the wall of the esophagus.

# 8. CONCLUSION:

Boston Scientific Corporation has demonstrated that the proposed Hemostasis™ Clipping Device can be safely and effectively used for its proposed expanded indication.
