Aquamantys System

and Bipolar Sealers

Clinical Outcomes for Orthopaedic Surgery

Clinical Studies

Many clinical studies have been published about Transcollation® technology, a combination of radiofrequency (RF) energy and saline that provides hemostatic sealing of soft tissue and bone during surgery. Below are a few key studies and their corresponding results.

Reductions in Blood Loss with a Bipolar Sealer in Total Hip Arthroplasty¹

Marulanda et al. demonstrated a statistically significant difference in intra- (p = 0.002) and post-operative (p = 0.001) blood loss using the Aquamantys System. They also demonstrated a reduction in both allogeneic and autologous transfusion rates from 28% to 23% and 24% to 12% respectively. Transfusions overall were significantly reduced from 53% to 20% (p = 0.005).

Hemostasis Using a Bipolar Sealer in Primary Unilateral Total Knee Arthroplasty⁵

This multi-center prospective randomized trial demonstrated that the amount of blood loss and decrease in post-operative hemoglobin were significantly lower in the bipolar sealer group (p = 0.0073 and p = 0.0417 respectively).
