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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Description

Inclusion Criteria:

  • Patient is ≥ 18 years of age
  • Signed informed consent*
  • Patient is to undergo or has undergone embolization with Obsidio™ Conformable Embolic
  • Patient is willing and able to comply with protocol requirements, including all procedures, clinical evaluations, and follow-up visits *Patients being treated for control of bleeding/hemorrhage who are unable to consent prior to their procedure, can be enrolled if the informed consent is provided and signed within 72 hours of the index procedure

Exclusion Criteria:

  • Patient has a life expectancy < 30 days

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
Primary safety endpoint
Time Frame: 30 days following index procedure
The primary safety endpoint is freedom from major adverse events defined as non-target embolization events that meet serious adverse event criteria, unintended target organ or soft tissue infarction, vessel perforation/injury and catheter entrapment through 30 days of the index procedure.
30 days following index procedure
Primary effectiveness endpoint
Time Frame: Immediately following index procedure
The primary effectiveness endpoint is technical success, which is defined as occlusion of the target vessel(s) after embolization with Obsidio™ Conformable Embolic as assessed via angiography or demonstration of a cast of Obsidio occluding the artery on fluoroscopy or image acquisition immediately following the index procedure.
Immediately following index procedure

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
