The GORE® VIABAHN® FORTEGRA Venous Stent Post-Approval Study

This study is a prospective, multicenter, single-arm post-market clinical study to evaluate the GORE® VIABAHN® FORTEGRA Venous Stent in real-world use.

The GORE® VIABAHN® FORTEGRA Venous Stent Iliofemoral Study

This study is a prospective, non-randomized, multicenter, single-arm, clinical study to evaluate the performance, safety and efficacy of the GORE® VIABAHN® FORTEGRA Venous Stent (formerly known as GORE® VIAFORT Vascular Stent) for treatment of symptomatic iliofemoral venous obstruction.

US Post-Market Surveillance Study of the Surfacer System

Single arm, observational, multi-center, consecutively enrolling, post-market surveillance study. Treating patients in need of central venous access who have upper body venous occlusions or other conditions that preclude central venous access by conventional methods, and who meet the requirements described in the device labeling.

The GORE® VIABAHN® FORTEGRA Venous Stent IVC Study

This study is a prospective, multicenter, non-randomized, single-arm study to evaluate the performance, safety, and efficacy of the GORE® VIABAHN® FORTEGRA Venous Stent (formerly known as GORE® VIAFORT Vascular Stent) for treatment of symptomatic inferior vena cava obstruction with or without combined iliofemoral obstruction in adult patients.

Vascular Lab Resource (VLR) Biorepository

This is a study of biomarkers obtained from prospectively collected subject samples and their correlation with cardiovascular and metabolic diseases. The purpose of this initiative is to develop an enduring tool to allow for collaborative research between clinicians at Cleveland Clinic Main Campus and basic scientists at the Lerner Research Institute. This collaboration will allow resources to be available to clinical and basic researchers alike. This tool will enable research of vascular disease in the Vascular Lab and will leverage this valuable asset to the fullest extent to allow for interdepartmental collaboration.

Training of a Artificial Intelligence Model to Detect Venous Diseases Using PPG Technology

This clinical research aims to evaluate the effectiveness of using Photoplethysmography (PPG) signals combined with Artificial Intelligence (AI) algorithms, for the precise classification and diagnosis of Venous Diseases of the lower limb. This study invites a group of participants who currently undergoing investigations for venous disease at The Whiteley Clinic (hereinafter referred to as TWC). The Participants will be classified into control (healthy individuals with no significant venous disease) and chronic venous disease (CVD) (diagnosed with proven venous disease) groups. Prospective participants who express an interest in being included in the study will be given a patient information sheet and will undergo a briefing of the pilot study. If they consent and sign the relevant consent forms, the participants will perform a series of standardized exercises under the supervision of a consultant vascular surgeon. Throughout the exercises, a data acquisition device attached to the ankle records the PPG signals, capturing the changes in blood volume due to the reflected PPG signals from the red blood cells during the movement. Thus, once the data is collected and recorded, this allows for the analysis of the data of the control group and CVD group against each other. During the analysis of the two groups' PPG signals, the objective lies within the capability to detect subtle nuances in the patterns of the PPG signals during the performed movements using AI algorithms. The AI algorithms will distinguish patterns or features indicating the presence or absence of venous disease. This study seeks to contribute valuable insights into enhancing the diagnosis of venous disease using PPG and AI algorithms, paving novel approaches to Venous healthcare.
