Aquamantys™ bipolar sealers use proprietary Transcollation™ technology, combining radiofrequency (RF) energy and saline to provide haemostatic sealing of soft tissue and bone without the smoke or char found in other methods. The combination of RF energy and saline allows the device to operate at approximately 100˚C — nearly 200˚C less than traditional electrosurgical devices. By controlling bleeding, the Aquamantys has been shown to significantly reduce the incidence of haematoma and reduce surgical time in a variety of procedures, and may reduce the need for haemostatic agents.

Use in Hip Arthoplasty
Aquamantys bipolar sealers are sterile, bipolar electrosurgical devices intended to be used in conjunction with the AEX and Aquamantys pump generators for delivery of RF energy and saline for haemostatic sealing and coagulation of soft tissue and bone at the operative site.
These illustrations show how the Aquamantys achieves haemostasis with heat-induced collagen shrinkage in blood vessel walls.
- RF energy and saline are applied to tissue
- Heat-induced collagen shrinkage occurs
- Vessels ˂1 mm may be occluded
- Significantly reduced total blood loss compared to traditional electrosurgery
- Improved visualization of the surgical site
- Reduced operating room time during infected total hip arthroplasty (THA) revisions
- Reduced surgical time in spine surgery
- May reduce exposure to surgical smoke for surgeons and operating room staff
- May reduce the need for other haemostatic agents
- Reduced length of stay in primary THA by 12% (2.86 vs. 3.26 days, p < 0.0001)
- Increased number of patients discharged to home self-care following primary THA (33.6% vs. 24.1%, p < 0.0001)
- Less reduction in haemoglobin levels compared to traditional electrosurgery (3.4±1.3 vs. 3.0±1.2 g/dL, p=0.041)
- Reduced post-operative pain and swelling leading to reduced incidence of hemarthrosis
- 75% reduction in hematomas in THA (0.2% vs. 0.8%, p = 0.0024)
- Reduced blood transfusions compared to traditional electrosurgery (73%; 52% vs. 20%; p = 0.005)
- Reduced allogeneic blood transfusions may result in reduced post-operative infections and complications
- Reduced transfusion rates may contribute to reduced length of hospital stay
- $740 savings per case on blood product costs due to lower transfusion rates
- More patients discharged to home or self-care vs. skilled nursing facilities or home health after hip arthroplasty, — associated with a savings of $978–$4,486 to the healthcare system
- Reduced transfusion rates, which may lower costs to the hospital
