OVERVIEW · Product overview

Redefining vascular management in companion-animal surgery

V-Clamp is a canine-specific interventional mitral valve repair device independently developed by Hongyu Medical. Based on transcatheter edge-to-edge repair (TEER) technology, it is one of the surgical devices available worldwide for treating mitral regurgitation in dogs.

FEATURES · Technical advantages

Three core technology advantages

Every design choice is aimed at safer, more efficient surgical outcomes.

Technical principle

Technical principle

The product is based on the principle of transcatheter edge-to-edge mitral valve repair, which has been widely used in human medicine and proved to be safe and effective. The human application of the product has also shown satisfactory results.

Implantation path

Implantation path

Implantation from the apex. The catheter operation time is short （about 20 minutes, making the procedure more safely.

Guiding Image

Guiding Image

The procedure can be performed just using echocardiography.

Minimally invasive advantages

Minimally invasive advantages

No cardiac arrest is required, with minimal trauma and fast recovery. The catheter is only 6F or 14F. The device can be repeatedly clamped, and the clamping position is adjustable without damaging the leaflets.

Structural technology

Structural technology

Multiple sizes of devices can be selected for various dogs. Multiple clamps can be implanted to enhance the effect of procedure.

CLINICAL · Clinical applications

Built for multi-scene veterinary surgery

Whether in a specialized cardiac center, a teaching hospital, or a general veterinary practice with interventional capabilities, it enables minimally invasive repair of canine mitral regurgitation through transcatheter edge-to-edge repair (TEER), using a small transapical incision under echocardiographic and fluoroscopic guidance while the heart continues to beat. Designed to adapt to different dog sizes, anatomies, and operator needs, V-Clamp combines precision engineering with clinical flexibility to help veterinarians achieve greater surgical precision, less trauma, and better postoperative recovery across diverse clinical environments—making canine mitral valve repair a reproducible, scalable solution for veterinary practice worldwide.

  • Abdominal surgery: Splenectomy, hepatic lobectomy, nephrectomy, adrenal tumor excision
  • Soft-tissue surgery: Thyroidectomy, ovariohysterectomy, local tumor resection
  • Orthopedic support: Intraoperative bleeding control and periosteal vessel closure
  • Emergency surgery: Rapid hemostasis for traumatic hemorrhage

V-CLAMP 100Entry · Small dogs & cats
V-CLAMP 100
Vessel 2–4 mm · Clamping force 5–9 N · Response ≤1.5 s · Ti-6Al-4V · EO sterile · 36-month shelf life
V-CLAMP 100 is the entry model of the V-CLAMP vascular closure platform, engineered for small dogs and cats with vessel diameters between 2 mm and 4 mm. A miniature pressure sensor reads clamping force in real time and holds the jaw within the optimal closure window, so the vessel wall is sealed without being crushed. The medical-grade titanium alloy jaw carries a biocompatible coating that has passed ISO 10993 cytotoxicity testing, and the one-handed quick-release mechanism lets the surgeon withdraw the instrument within three seconds of closure. Typical use covers ovariohysterectomy, splenectomy, thyroidectomy, and local tumor resection in patients from 2 kg to 15 kg.

V-CLAMP 200Standard · Medium dogs
V-CLAMP 200
Vessel 4–6 mm · Clamping force 7–12 N · Response ≤1.5 s · Ti-6Al-4V · EO sterile · 36-month shelf life
V-CLAMP 200 is the standard configuration of the V-CLAMP platform, covering vessel diameters from 4 mm to 6 mm in medium-breed dogs. It carries the same adaptive pressure-feedback loop as the entry model but with a wider jaw and a 7 N to 12 N force window, making it the default choice for routine abdominal and soft-tissue procedures in patients from 12 kg to 30 kg. The reinforced shaft holds alignment at greater working depth, and the biocompatible titanium coating is unchanged from the rest of the family.

V-CLAMP 300Advanced · Large dogs
V-CLAMP 300
Vessel 6–8 mm · Clamping force 10–15 N · Response ≤1.5 s · Extended jaw · EO sterile · 36-month shelf life
V-CLAMP 300 is the advanced configuration of the V-CLAMP platform, rated for vessel diameters from 6 mm to 8 mm in large-breed dogs. The 10 N to 15 N adaptive force window and extended jaw are specified for high-flow hilar vessels, and the long shaft reaches deep abdominal and thoracic sites without losing alignment. It is the model used for emergency hemorrhage control in patients above 25 kg.
