Sealing lymphatics* and decreasing post-operative drainage†, ‡
HARMONIC FOCUS® Curved Shears offer technology that helps decrease post-operative drainage.†, ‡
You often operate on compromised patients, and even under the best circumstances, it can be hard for them to heal. You want to reduce drainage and to avoid lymphoceles and seromas, and HARMONIC FOCUS Curved Shears can help. It seals lymphatics, and it cuts, coagulates, grasps and dissects.
HARMONIC® Technology enables precision with minimal thermal damage for soft tissue incision, coagulation, skeletonization and mobilization. HARMONIC® Devices, including open and laparoscopic blades and shears, can be used to obtain exposure to vasculature in procedures including:
Groin Dissection:
- Endovascular Abdominal aortic aneurysm (AAA) repair
- Femoral-Femoral Bypass
- Femoral-Popliteal Bypass
- Femoral-Tibial Bypass
HARMONIC Technology:
Mechanical, not electrical energy
- Precisely directed mechanical energy – a blade vibrating at 55,500 Hz – denatures tissue and transforms it into a sticky coagulum.
- Pressure from the blade surface collapses blood vessels and allows the coagulum to form a reliable hemostatic seal.
- No electricity passes to or through your patients, eliminating current induced neuromuscular stimulation and the need for a grounding pad.
Minimal thermal tissue damage
- HARMONIC Devices operate at a lower temperature compared to electrosurgery.
- Minimal lateral thermal spread, or spread of heat from the HARMONIC Blade to adjacent tissue.
You control the tissue effect
You control cutting and coagulating precision by varying the power level, blade edge, tissue tension, blade pressure and the time on tissue.
HARMONIC® Devices have been used worldwide in more than 14 million surgical procedures§ in a variety of specialties, including peripheral vascular surgery, plastic surgery, general surgery, urology, gynecology, ENT surgery, and thoracic surgery and have been cited in over 590 peer reviewed journal articles.
Strength and Protection
Wound closure plays an integral role in patient outcomes. While the fascia and skin heals, the wound closure device provides the necessary strength and support to maintain wound integrity and avoid complications such as dehiscence and surgical site infections.155
To achieve excellent outcomes during wound closure, Ethicon offers several innovative technologies, including:
- STRATAFIX™ Knotless Tissue Control Devices – with significantly more points of fixation than traditional sutures, STRATAFIX™ Devices provide a combination of more consistent control, strength and security, and more efficiency
- DERMABOND® Portfolio – transform skin closure with a complete set of solutions that add strength and protection against bacterial contamination to an incision1,117
- Plus Antibacterial Sutures – the only commercially available suture that protects against colonization of the suture by pathogens commonly associated with surgical site infections

- † In a prospective study (n=70), use of HARMONIC was associated with fewer days with drain (2 days [HARMONIC] vs. 4 days [monopolar electrosurgery], p<0.001) and reduced cumulative serous drainage (200 +/- 130 mL [HARMONIC] vs. 450 +/- 230 mL [monopolar], p<0.05) after performing axillary dissection for breast cancer. HARMONIC WAVE® Open Shears (WAVE18S) were used in this study.110
- ‡ In a randomized prospective preliminary study (n=76), cumulative serous drainage from the axilla (407.6 +/- 136.1 ml ultrasound [HARMONIC] v. 492.4 +/- 153.4 ml [cold steel]) and the number of days with drain (5.1 +/- 1.3 days ultrasound v. 6.3 +/- 1.5 days) were significantly lower (P<0.05) with ultrasound [HARMONIC] (N=38) after performing axillary dissection. HARMONIC Coagulating Shears (CS14C) were used in this study.10
