The Simplest Way To Manage Ascites
ARCA® and ARCA+ are fully implantable, manual systems made entirely out of medical-grade silicone. Both are designed to manage ascites, independently and safely, allowing patients to drain their peritoneal liquid whenever, wherever.
While both devices are based on the same physical principles, ARCA+® is the standard system suitable for most patients, which allows the transfer of liquid from the peritoneal cavity to the bladder for natural urination. ARCA® is an adapted version specifically designed for patients without a bladder, so that they too can manage their ascites easily, at home, and independently by transferring the peritoneal liquid from the peritoneal cavity to outside the body through an opening in the skin.
Together, they empower all patients to manage ascites independently, regain control over their daily routines, and improve their overall quality of life.
What is ascites?
Ascites is a condition in which fluid accumulates in the abdomen, causing noticeable swelling and discomfort. It is most commonly associated with liver disease, such as cirrhosis, where scarring impairs liver function. As liver damage progresses, pressure increases in the surrounding blood vessels, causing fluid to leak into the abdominal cavity.
This buildup of peritoneal fluid can lead to a variety of complications, including:
- Spontaneous bacterial peritonitis (infection of the fluid)
- Abdominal pain and discomfort
- Difficulty breathing
- Hernias and reduced mobility
- Malnutrition
- Edema in the legs, knees, and other areas

For patients, ascites can mean not only physical symptoms but also frequent hospital visits, invasive procedures, and a loss of independence.
A manual pump designed for patient freedom

By allowing regular, controlled drainage of peritoneal fluid, ARCA®
significantly reduces the risk of spontaneous bacterial peritonitis (SBP), the most severe complication associated with ascites.
Why? Because when fluid is not allowed to accumulate, bacterial translocation is prevented bringing the risk of SBP close to zero.
Benefits That Go Beyond Infection Prevention
Restored appetite
Respiratory comfort
Better mobility
Lower incidence of hernias
Less overall discomfort
Reduced swelling in the legs
Potential increase in life expectancy
Effortless Autonomy.
Everyday Freedom.
With ARCA®
, patients no longer need weekly hospital visits or invasive procedures like paracentesis.
As ascitic fluid builds up, it can be manually drained at home anytime, anywhere by the patient, independently and safely.
The ARCA® system is designed to signal when it’s time to drain, giving patients confidence and control over their condition.

Only for ARCA
Starter Kit
Each ARCA® implant comes with a complete starter drainage kit, providing everything needed for safe and easy use.
Monthly Refill Kits
Patients can then subscribe to a monthly delivery plan, which includes all necessary components to continue the drainage process seamlessly without complications.

Esteban R., 32
“My father has had cirrhosis for years, and ascites was always his biggest struggle. Watching him go to the hospital every week and come back exhausted was heartbreaking. ARCA changed everything.
Now he manages his treatment at home, and we all feel more at ease. He’s regained his energy—and even started going out for walks again. It was a decision that brought dignity and peace back to our whole family.”

Elena M., 54
“ARCA has truly been a blessing for me. Being able to drain at home, pain-free and whenever I need to, completely changed my routine.
I no longer live in fear of rushing to the hospital or wondering if they’ll have room for me.
I feel lighter, more confident, and less worried. It’s simple, but powerful.”

Carlos G., 61
“Before ARCA, I had to go to the hospital every week to have fluid drained. I was tired, frustrated, and constantly afraid of getting another infection.
Since I got the ARCA implant, I’ve taken control of my life again.
I no longer rely on the hospital or anyone else to manage my ascites. I feel more free, more active, and so much more at peace.”

Frequently Asked Questions About ARCA®
What is ARCA®?
ARCA® is a fully implantable, manual system that allows patients with ascites to safely drain excess abdominal fluid from the comfort of home, on their own.
How does ARCA® work?
The system works through basic physical pressure. The patient manually activates the pump to transfer fluid from the abdominal cavity to the outside of the body through a controlled drainage port.
What are the advantages over paracentesis?
ARCA® eliminates the need for weekly hospital visits, significantly reduces infection risk, and empowers patients with more comfort, freedom, and independence.
Does ARCA® require batteries or charging?
No. ARCA® is completely mechanical. It does not rely on batteries, software, or electronics—making it safer and easier to use.
Can I use ARCA® if I have limited mobility?
Yes. ARCA® is designed to be simple to use, either by the patient or with the help of a caregiver. It requires no strength or complex movements.
Is ARCA® safe?
Yes. It is made of medical-grade silicone and developed under strict safety and quality standards. It also reduces the need for repeated punctures, lowering infection risks.
Does the system tell me when to drain?
Yes. ARCA® includes a visual indicator that lets the patient know when it’s time to activate the drainage process.
