About this study
Official title: Evaluating the Use of the FiberNet® Embolic Protection System in Saphenous Vein Grafts: The RETRIEVE Study
This is a multicenter, prospective study designed to demonstrate the performance and safety of the FiberNet Embolic Protection System when used as an adjunctive device during saphenous vein graft (SVG) intervention.
Read the detailed description
The study will involve up to 30 patients to be enrolled using the FiberNet device during clinically indicated percutaneous intervention of SVG and followed through 30 days post procedure. Patients will be enrolled at up to 10 Investigative Sites. The study is a prospective multi-center registry with sequential enrollment of qualified patients who consent to participate and meet all entrance criteria.
The Lumen Biomedical, Inc. FiberNet® Embolic Protection System is indicated for use as a guide wire and embolic protection system to capture and remove embolic material (thrombus/debris) produced while performing percutaneous transluminal interventional procedures in saphenous vein grafts with reference vessel diameters of 1.75 mm to 7.0 mm.
- Conditions

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
FiberNet EPS used during SVG intervention.Device
Also called stenting
The FiberNet EPS is indicated for use as a guide wire and embolic protection system to capture and remove embolic material produced while performing percutaneous transluminal interventional procedures in saphenous vein grafts.
What is being measured
The primary outcome is the main question the study is designed to answer.
The primary objective of the study is to evaluate the safety and performance of the FiberNet Embolic Protection System. The primary endpoint is major adverse cardiac events (MACE) rate at 30 days.
Measured: 30 days
Secondary outcomes (1)
The secondary study objectives are endpoints related to the use of the FiberNet system and additional safety endpoints.
Measured: index hospitalization

Questions about this trial
What is this clinical trial studying?
A study testing FiberNet EPS used during SVG intervention. in people with Saphenous Vein Graft Disease and Myocardial Ischemia, run by Lumen Biomedical at 6 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The primary objective of the study is to evaluate the safety and performance of the FiberNet Embolic Protection System. The primary endpoint is major adverse cardiac events (MACE) rate at 30 days. (time frame: 30 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2009; AzTrials last refreshed its copy on 7 Nov 2026.
