Details and patient eligibility

About

The purpose of this study is to evaluate and document appropriate clinical safety and performance of the Remon CHF Implantable Pressure Sensor including the corresponding delivery system, the Remon CHF Home Unit, the Remon CHF Clinic System devices and associated application software. It is a small clinical trial to determine the feasibility of the device. The primary outcome measure relates to feasibility and not to health outcomes.

Full description

This study was a prospective feasibility, non-randomised, singlearm, multi-centre, interventional clinical investigation performed at 4 international sites. Patients were implanted with the Remon CHF Implantable Pressure Sensor utilizing the corresponding delivering system. Measurements were taken with the Remon CHF Home Unit and the Remon CHF Clinic System. Follow-up visits took place at one, three and six months after implant.

Per protocol, a minimum of 30 patients was required to demonstrate safety of the device.

The study was conducted in accordance with ISO 14155:2003 (parts I and II), the Declaration of Helsinki and all applicable local and national regulations in the countries of submission.

Enrollment: 42 patients

Sex: All

Ages: 18 to 99 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients who exhibit signs and symptoms of NYHA Class III or IV heart failure.
• Patients who are able to visit the clinic frequently during the 6 months following implantation.
• Patients who are willing and able to perform all follow-up procedures.

Exclusion criteria

1. Patients under the age of 18
2. Pregnant women or women that plan to get pregnant during the study.

5. Patients suffering from active infection (on antibiotic therapy)
6. Known intracardiac mass (right atrial or right ventricular)
7. Patients who have been implanted with a VAD
8. Patients who are candidates for listing for heart transplantation if it is deemed that they have a possibility of receiving a heart within the next 6 months
9. Patients that have lead implanted at the heart right side of the heart within the last 6 months
10. Patients with any terminal illness, or with a life expectancy of less than 6 months
11. Patients that are unable to lie flat for the duration of the procedure
12. Patients that are unable to operate the home unit (due to physical or mental constrain)
13. Patients after pneumonectomy
14. Patients treated with oral anticoagulants INR > 1.5 prior to catheterization
15. Patients with severe chronic renal failure (creatinine > 2.5 mg/dl)
16. Patients suffered from acute myocardial infarction within the three months prior the study
17. Patients that underwent open heart surgery within 4 weeks prior the study.
