Stroke Clinical Trial - Feasibility & Safety Study of LAmbre Left Atrial

Status Completed

Clinical Trial Summary

This study mainly evaluated the feasibility and safety of LAmbre Left Atrial Appendage Occluder which is to prevent ischemic stroke caused by atrial fibrillation(AF).

Clinical Trial Description

Atrial fibrillation (AF) is a common arrhythmia, its incidence increases with age. Thrombosis shed off caused by AF is one of the major causes of stroke. Most patients with AF suffer ischemic stroke that the thrombosis was from the left atrial appendage(LAA). The majority of patients with atrial fibrillation, the blood clots come from the left atrial appendage, so close the left atrial appendage can reduce cycle thromboembolism of the patients with AF. Now patients have cardiac surgery and risk at left atrium related thromboembolism, the surgery has been conventional perform the left atrial appendage closed surgery.

However, surgical left atrial appendage ligation is difficult to be completely closed to the left atrial appendage,internal medicine intervention methods of surgical closure the left atrial appendage is relatively simple, minimally invasive, high success rate and is expected to be widely used.

Several versions of LAA occlusion devices have been developed.LAA occluder of Lifetech consists of a umbrella, cover and conveyor; The umbrella composed of multiple umbrella and covered the ePTFE membrane.This study mainly evaluated the feasibility and safety of LAmbre Left Atrial Appendage Occluder! Through the femoral vein puncture; insert inter atrial septum puncture device; puncture a small hole in the atrial septal, delivery sheath is inserted in the femoral vein puncture site and across the atrial septal reach the left atrial appendage, establishment of the channel. Through the built-channel sent the LAA occluder to the left atrial appendage by the delivery cable; The LAA occlude will be fixed in the left atrial appendage, close the entrance of the left atrial appendage meanwhile and block blood flow; then eliminate the risk of blood clots due to atrial fibrillation, prevention stroke. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
