What is Sealk?

Sealk is all-natural, plant based, biocompatible, water soluble, etherified sodium carboxymethyl cellulose matrix that utilizes patented technology to achieve superior hemostasis.

Powered by BloodSTOP IX Advanced Hemostat with WoundHeal

FDA approved for wound hemostasis

Activates growth factors, promoting tissue regeneration and angiogenesis

Decreases inflammatory cytokines, reducing infection and inflammation risks.

Supports postoperative wound management

Designed for use following tonsil and adenoid surgery
Conforms to and adheres to wound sites
Rapid hemostasis (bleeding control) for minor to larger wounds

Sealk utilizes advanced technology that provides power to control bleeding. Once applied to the wound and upon contact with blood, exudates (fluid from a wound or incision), or body fluids, Sealk turns into a sticky transparent gel.

Sealk stops bleeding, initiates blood coagulation, forms a protective membrane layer. This lowers the need for cauterizing (burning) wounds, especially in younger children, and reduces the need and time for pain medications. It is also easily removable without disruption of the clotted surface.

Advanced Wound Care Technology	How it Works
Sealk is an FDA-approved complete wound care solution for surgical bleeding control that also helps with aftercare. Following ENT procedures, such as tonsil or adenoid surgery, kids typically have sore throats, a hard time swallowing, and there is a lot of discomfort. If a scab comes off of the wound they could also cough up blood or choke. Sealk is less irritating on the throat, and there is less scabbing on the wound.	Sealk utilizes advanced technology that provides power to control bleeding and quickly heal. Once applied to the wound and upon contact with blood, exudates (fluid from a wound or incision), or body fluids, Sealk turns into a sticky transparent gel. Sealk is reliable and fast acting which allows surgeons to focus on the operative tasks with confidence and helps the patients recovery be more manageable. Sealk stops bleeding fast, initiates blood coagulation, forms a protective membrane layer, creating an optimal environment for fast wound healing. This lowers the need for cauterizing (burning) wounds, especially in younger children, and reduces the need and time for pain medications. It is also easily removable without disruption of the clotted surface.

Clinical Indications

Sealk is indicated for use as an adjunctive hemostatic and protective wound dressing in ENT surgical procedures where control of bleeding and post-operative tissue protection are desired.

Primary Indications

Tonsillectomy (pediatric and adult)

Adenoidectomy

Tonsillectomy with adenoidectomy (T&A procedures)

Patient Profile

Sealk may be considered in:

Pediatric tonsillectomy patients

Patients at higher risk of post-operative pain or dehydration

Cases where minimizing opioid use is desired

Patients requiring enhanced post-operative recovery experience

Clinical Use Case

Sealk is applied intraoperatively to the tonsillar fossae following removal of tonsillar tissue to:

Assist in hemostasis at the surgical site

Provide a protective gel barrier over exposed tissue

Support improved wound healing conditions

Reduce post-operative discomfort associated with scab formation and tissue exposure

Surgical Timing

Applied immediately following tonsil removal

Delivered directly to the surgical site prior to completion of procedure

Does not require additional OR time or specialized equipment

Mechanism of Action (Clinical Summary)

Sealk forms a transparent, adherent gel layer over the surgical wound, which:

Supports hemostasis

Maintains a moist wound environment

Reduces scab formation severity

Protects exposed nerve endings during healing

Why This Matters in Tonsillectomy

Peak pain occurs Days 7-10 due to scab separation

Traditional healing leaves exposed tissue vulnerable

Sealk provides a protective barrier through this critical window

Real-world feedback from the people who experience Sealk every day.

My honest review: easy to use I use it on ALL tonsillectomy patients. My post op bleed rate has always been low (1-2%) and have always allowed return to regular diet night of surgery, so I think it will take a while to determine if it moves the needle on any measurable data, at least for me personally. No change in postop pain management: scheduled alternating ibuprofen and acetaminophen. Surgery technique: Colorado tip tonsillectomy with hemostasis using bipolar forceps.

Sealk is an intuitive product for ENTs to integrate into their surgical practice. Having used it over 2 years for patients, parents and PACU staff all notice a pain reduction. On top of that, my partners and myself have all noticed a reduction in post-op bleeding. I have yet to have a single adverse outcome since I started using it.

I have had the privilege of helping children and adults with Tonsil disease for over 25 years. Although there is no one answer, the Sealk has definitely helped since it was introduced. It has helped with decreasing the number of post-op hemorrhages in the first seven days after surgery, diminished post-operative halitosis and decreased the pain level in the immediate post-op period.

As a nurse with 25 years of experience in the medical field, I have seen my fair share of post-tonsillectomy recoveries, and I can confidently say that my daughter’s recent experience was a revelation, all thanks to the innovative tonsil patch device.

I am a scrub tech and have been in over 500 tonsillectomy procedures. I understand the procedure and recovery thoroughly, and was very nervous and anxious about my daughter’s recovery from her upcoming tonsillectomy. We were introduced to an FDA wound healing product called Sealk. We were told it would potentially help reduce her pain and speed up her recovery. We agreed to have Sealk applied during her procedure and were pleasantly surprised with her results. Her pain seemed much less than we expected, and she didn’t struggle like I expected. I would encourage everyone to enquire about Sealk.

The convenience of the tonsil patch cannot be overstated. Its application was simple, and it stayed in place throughout the recovery period, providing a continuous source of relief. The patch seemed to accelerate the healing process, as my daughter’s recovery progressed rapidly and without any setbacks.
