• Conditions: Venous Stenosis; Venous Occlusion

• Registration Number: NCT06807099
• Lead Sponsor: Merit Medical Systems, Inc.

Brief Summary

The goal of this observational study is to investigate the safety and efficacy of the WRAPSODY CIE in a real-world North American population. Participants treated with the WRAPSODY CIE device in accordance with the device instructions for use will be followed in accordance with standard of care up to 3-years post-procedure.

Detailed Description

Primary Outcome Measures

Name	Time	Method
Proportion of subjects with Target Lesion Primary Patency (TLPP) (Primary Effectiveness Endpoint)	6 months	The proportion of subjects with Target Lesion Primary Patency (TLPP) at 6 months.; Target Lesion Primary Patency (TLPP) defined as freedom from clinically-driven target lesion revascularization (CD-TLR) or target lesion thrombosis measured through 6 months post-procedure, which is the time interval of uninterrupted patency after study procedure to the next intervention performed on the target lesion or uncorrectable target lesion occlusion.
Proportion of subjects without any localized or systemic safety events (Primary Safety Endpoint)	30 days	Proportions of subjects without any localized or systematic safety events through 30 days post-procedure that affect the access or venous outflow circuit and resulted in reintervention, hospitalization, or death (not including CD-TLR or target lesion thrombosis)

Secondary Outcome Measures

Name	Time	Method
Proportion of subjects with Target Lesion Primary Patency	12, 24 and 36 months	Proportion of subjects with Target Lesion Primary Patency at months 12, 24 and 36.
Proportion of subjects with Assisted Target Lesion Primary Patency (aTLPP)	6, 12, 24 and 36 months	Proportion of subjects with Assisted Target Lesion Primary Patency (aTLPP)
Proportion of subjects with Access Circuit Primary Patency (ACPP)	6, 12, 24 and 36 months	Proportion of subjects with Access Circuit Primary Patency (ACPP)
Rates of procedure- and device-related adverse events	Index procedure, 30 days and 6 months	Number of subjects with procedure- and device-related adverse events
