Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Patients with stenosis or occlusion at the venous anastomosis of synthetic arteriovenous (AV) access graft in Japan.

Description

Inclusion Criteria:

  • Participants who developed stenosis or occlusion at the venous anastomosis of synthetic arteriovenous access graft
  • Participants who was used to repair vascular access circuits for purposes other than treatment of stenosis or occlusion at the venous anastomosis of synthetic arteriovenous access graft

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame

Time Frame: Day 1
Technical Success is defined as < 30% residual stenosis after initial treatment.
Day 1
Number of Subjects Achieving Clinical Success
Time Frame: Day 1 to Month 1 follow up
Clinical Success is defined as the resumption of normal dialysis for at least one session after the initial treatment.

Time Frame: Day 1 to Month 1 follow up
A device defect is defined as a defect such as damage, malfunction, etc. that are widely unfavorable. Regardless of whether they are due to design, marketing, distribution, or use.

up to 2 years
Number of Subjects With Loss of Secondary Patency of Target Lesion
Time Frame: up to 2 years
Secondary patency of target lesion is defined as the period during the patency was maintained from initial treatment (including the period of patency after re-treatment).
up to 2 years
Number of Subjects With Loss of Primary Patency of Vascular Access Circuit
Time Frame: up to 2 years

up to 2 years
Number of Subjects With Loss of Secondary Patency of Vascular Access Circuit
Time Frame: up to 2 years
Secondary patency of vascular access circuit is defined as the period during the patency was maintained from initial treatment until discontinuation of the use of vascular access circuit.
up to 2 years
Mean Cumulative Number of Re-treatment Per Target Lesion
Time Frame: at 24 months
Mean cumulative number of re-treatment in target lesion is defined as the number of re-treatment performed for target lesion after the initial treatment.

An adverse event (AE) is defined as any unfavorable or unintended sign (including abnormal laboratory changes), symptom, or illness associated with the use of a medical device. Unless worsening of severity or increasing of incidence during the surveillance, the primary disease of the patient is not considered an adverse event.
