Brief Summary:
This clinical trial is to verify the safety and effectiveness of the Non-adhesive Liquid Embolic System(NALES) produced by Suzhou Hengrui Hongyuan Medical Technology Co., Ltd. in the process of clinical use to support the application of the National Medical Products Administration ( NMPA) product registration approval.

Condition or disease Intervention/treatment Phase
Intracranial Arteriovenous Malformations Device: embolism Not Applicable

Detailed Description:
A prospective, multicenter, randomized controlled trial was used in this study. Onyx Liquid Embolic System and Marathon Flow Directed Micro Catheter, which were registered and marketed in China and had good effect in the industry, were selected as the control devices. Subjects requiring cerebral arteriovenous malformation embolization were selected to participate in the trial based on pathological conditions and inclusion/exclusion criteria, and the use of test products or control products was determined based on central randomized results. Imaging data involving the main evaluation criteria were evaluated uniformly by the blind evaluators of the leading unit, so as to reduce the bias caused by subjective factors of different evaluators.

Official Title: A Prospective, Multi-center, Randomized Parallel Controlled Study on the Safety and Effectiveness of the Non-adhesive Liquid Embolic System in the Embolization of Cerebral Arteriovenous Malformations
Estimated Study Start Date : October 17, 2021
Estimated Primary Completion Date : October 17, 2023
Estimated Study Completion Date : October 17, 2024

Arm Intervention/treatment
Experimental: Non-adhesive Liquid Embolic System(NALES) Device: embolism
Cerebral arteriovenous malformation embolism

Active Comparator: Onyx Liquid Embolic System& Marathon Flow Directed Micro Catheter Device: embolism
Cerebral arteriovenous malformation embolism

Primary Outcome Measures :
  1. Effective embolization rate of malformed masses [ Time Frame: Immediately after surgery ]
    Number of effective embolization subjects / Total number of subjects x 100%.Definition of effective embolization : Postoperative DSA angiographic malformation volume decreased ≥50%. Volume of malformed groups = length × width × height /2.

Secondary Outcome Measures :
  1. MRS score [ Time Frame: 1,6,12months after surgery ]
    MRS refers to the modified Rankin scale, which is used to measure the neurological recovery of patients after stroke. It has a scale of zero to six. The higher the score, the worse the neurological function. MRS scores were collected at 1, 6 and 12 months after the operation before discharge .

  2. Technical success rate [ Time Frame: Immediately after surgery ]
    Success is represented by the ability to reach the lesion and embolize the malformed mass of the intended target, followed by successful catheter withdrawal from the body

  3. Catheter performance evaluation [ Time Frame: Immediately after surgery ]
    1. The ability of the catheter to reach the lesion .
    2. The catheter has broken at the tip and perforated.
    3. Intravascular complications associated with catheters occurred.
    4. Degree of difficulty in tube withdrawal
    5. Catheter jam

Other Outcome Measures:
  1. Incidence of major adverse events related to device or surgical procedures within 1 month after surgery [ Time Frame: 1 month after surgery ]
    Major adverse events related to instrumentation or surgical procedures within 1 month after surgery: bleeding during embolization, catheter indwelling, bleeding after embolization, symptomatic cerebral infarction, and edema.
