Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Registrap is a prospective, single-arm, multicenter, observational registry of the Embotrap®II Clot Retriever (NEURAVI) open to any Neurointerventional Department in Europe with experience in mechanical thrombectomy with the EmboTrap® II device Clot Retriever (5 cases already done) and a number of stroke procedures/year greater than 30.

The EmboTrap®II Clot Retriever (Neuravi) is CE-marked and represents one of the possible treatment devices, chosen by physicians according to their experience and practice, in acute ischemic stroke treatment.

Being REGISTRAP an observational registry and considering that different approaches and devices are available on the market, the investigators are aware that operators' preferences could represent a selection bias. The Screening Log will collect all the stroke cases treated from each centre during the enrollment period to show the rate of EmboTrap®II Clot Retriever (Neuravi) use over the total cases treated and the reasons for choosing other devices. The registry will enroll at least 100 consecutive patients presenting within 12 hours from symptom onset with a Large Vessel Occlusion (LVO) on CTA or MRA in the Anterior or Posterior Proximal Cerebral Vasculature up to A1, M1, Dominant M2, P1 who will be treated using the EmboTrap®II Clot Retriever (Neuravi) as first intention and used according to the Instructions For Use. The registry objectives are to evaluate the efficacy/safety of the device Embotrap II Clot Retriever(Neuravi), as first line treatment in the restoration of cerebral blood flow in cases of acute ischemic stroke from Large Vessel Occlusion. Efficacy is considered when a "modified Treatment in Cerebral Infarction" (mTICI) score of 2b or greater is achieved in the vessel treated with the (Neuravi). Safety refers to the rate of procedure-related and device-related hemorrhages. Number and severity of hemorrhages will be evaluated considering site and size. The first follow-up control will occur at 1 to 10 days post-procedure, the second at 90 days+/-14 days. In addition to the sample, the patients meeting the inclusion criteria and treated using the EmboTrap®II Clot Retriever (Neuravi) as second intention, will also be included in the study and considered only for a specific secondary endpoint.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

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: 10 days
Procedure-related mortality rate

Restoration of cerebral blood flow
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
