Study summary

A Feasibility Study to evaluate the initial safety and performance of the RapidPulseTM Aspiration System in the treatment of patients with Acute Ischemic Stroke (AIS) due to Large Vessel Occlusion (LVO).

Read the detailed description

The purpose of this study is to evaluate the initial safety and performance of the RapidPulse Inc. RapidPulseTM Aspiration System as frontline approach for use in the treatment of patients with Acute Ischemic Stroke (AIS) due to Large Vessel Occlusion (LVO). This is a prospective, multi-center, open label study comparing the safety and performance of the RapidPulseTM Aspiration System with non-randomized retrospective controls who otherwise meet the same study inclusion/exclusion criteria. The study will enroll a maximum of 100 participants in the Treatment Arm and a maximum of 200 participants in the Control Arm at in up to 10 centers in Europe and/or Latin America. Subjects data will be collected through hospitalization with a 3 months post-procedure study visit.

What researchers measure

Primary outcomes

  1. First Pass Reperfusion Effect (FPE)

    Defined by modified Thrombolysis In Cerebral Infarction scale (mTICI 2c-3) flow in the target vessel

    Time frame: Intra-procedural

Secondary outcomes

  1. Frontline technical success

    Defined by mTICI ≥ 2b after the last pass with Study Device with no rescue therapy

    Time frame: Intra-procedural

  2. Good functional outcome measured by Modified Rankin Scale score of 0 - 2 at 90 days post index procedure

    The Modified Rankin Scale (mRS) measures neurological disability or dependence for stroke patients on a scale of 0 (no symptoms) to 6 (deceased)

    Time frame: 90 days

  3. Rate of Symptomatic intracranial hemorrhage (sICH) at 24 hours post-procedure

    Time frame: 24 hours

  4. All cause mortality rate

    Time frame: 90 days
