Manual Compression 15–20 mins 78% Higher risk
Mechanical Clips 3–5 mins 95% Minimal

Integration with standard 3.7mm working channels allows seamless use in endoscopic procedures. Boston Scientific’s EDUCARE platform further supports training for optimal deployment techniques.

How Hemostasis Clips Work

Single-step deployment systems redefine surgical accuracy. The Retentia device uses a slider mechanism activated by a thumb ring, transmitting 2.5–3.5N of force for secure vessel closure. This streamlined process minimizes operator effort while ensuring consistent results.

One-Step Deployment Mechanism

Biomechanical testing confirms the clip’s efficient force transmission. An ergonomic handle reduces fatigue during prolonged use, critical in complex interventions. Real-time tactile feedback guides precise placement, enhancing procedural confidence.

360-Degree Rotation for Precision

Articulation testing demonstrates a rotation range of 358°±2°, allowing adjustments in tight anatomical spaces. Compatibility with standard 3.7mm working channels ensures seamless integration with endoscopic tools. This flexibility supports optimal positioning across diverse surgical scenarios.

Key Features of Hemostasis Clips

Advanced materials elevate the reliability of surgical tools. The Retentia device exemplifies this with medical-grade 316L stainless steel and a 0.15mm PTFE coating. These features ensure durability, biocompatibility, and smooth operation during procedures.

Durable Stainless Steel Construction

The alloy used provides 450MPa tensile strength and 0.2% yield strength, surpassing industry standards. Corrosion resistance testing across pH 1–14 environments confirms stability in diverse clinical conditions. This reduces the risk of defects, with fewer than 0.01% manufacturing imperfections reported.

PTFE Coating for Smooth Passage

Polytetrafluoroethylene (PTFE) lowers the coefficient of friction from 0.8μ to 0.05μ, minimizing tissue trauma. Histological studies show reduced inflammatory response compared to uncoated alternatives. The coating’s uniformity ensures consistent performance regardless of device length or anatomical site.

PTFE Coating Reduced friction 0.05μ coefficient
Tensile Strength Structural integrity 450MPa

Sizes and Versatility

Precision in surgical interventions relies on selecting the right tools for specific anatomical needs. The Retentia system offers 9mm, 12mm, and 16mm configurations, catering to vessels ranging from 3–8mm in diameter. A size-selection algorithm ensures optimal closure force based on vascular dimensions.

Each box contains six units with individual sterile barriers, preserving integrity until opening. Reusable deployment systems undergo ethylene oxide sterilization, meeting stringent clinical safety standards. Radial force varies by size—1.2N for 9mm and 2.8N for 16mm—balancing secure closure with tissue protection.

Compatibility spans major endoscope models, streamlining use in gastroenterology and laparoscopy. The 12mm variant demonstrates particular efficacy in mid-range vascular applications, while the 16mm option suits larger vessels requiring higher compressive force.

Clinical Applications of Hemostasis Clips

Medical professionals increasingly rely on advanced tools for precise bleeding control in diverse surgical settings. These devices excel in both routine and complex interventions, offering reliable vessel closure across specialties.
