The alfapump® system is intended for single patient use only and for a period of up to 2 years in patients with refractory ascites due to liver cirrhosis or malignant ascites with a life expectancy of 6 months or less. Patients must be 18 years or older and may not be pregnant.
Clinicians and surgeons must be trained by Sequana Medical staff on how to implant and program the alfapump® as well as on how to train the patient to use the Smart Charger.
The patient must be able to read the Smart Charger Instructions for Use and must be trained by a clinician on how the Smart Charger is used to charge their alfapump®.
Surgical implantation of the alfapump® system should be postponed if there is an infection in the peritoneal cavity.
This diagnostic procedure is contraindicated due to possible movement of the alfapump®, damage to the pump circuitry, tissue damage in the vicinity of the alfapump® and/or catheter dislocation.
Hyperbaric oxygen therapy is contraindicated because the environmental conditions entailed in this therapy are out of the defined range of use for the alfapump® system.
Supersonic and high-frequency heat therapies should not be used on patients with the alfapump® system due to possible heating effects of the implanted alfapump®. If the therapy must be performed, it should not be applied in the immediate vicinity of the alfapump system or the surrounding areas. The alfapump system should be continuously monitored during the treatment and system function must be checked after the therapy.
TENS therapy should not be used on patients with the alfapump® system. If the therapy must be used, the TENS electrodes should be placed as close as possible to each other to reduce the spread of electricity, and as far away as possible from the alfapump®. After stimulation, alfapump® system function must be checked.
The circuitry of the alfapump® is protected against the energies normally induced by defibrillation. Nevertheless, complete protection is not possible. The implanted alfapump® can be damaged by defibrillation. Circumstances permitting the energy setting should not be higher than necessary for defibrillation and the distance between the paddles and the alfapump® should be at least 10 cm. After defibrillation, alfapump® system function must be checked.
The electronic circuit elements of the alfapump® can be damaged by radiation therapy. The alfapump® should be shielded during the therapy. Following the radiation treatment, the alfapump® system function must be checked.
Electrocautery should not be performed within 15 cm of an implanted alfapump® because it could damage the pump circuitry. For trans-urethral electro-resection of the prostate, it is recommended to place the neutral electrode on the buttocks or upper thigh, but not in the thoracic area. The alfapump® system function must be checked and monitored after the procedure.
Before applying any of the aforementioned procedures please contact Sequana Medical’s customer service or your local sales representative.
Pacemakers, implantable defibrillators and other active implants are not contraindicated but must be verified for proper functioning after implantation of the alfapump® system.
