Incidence of Adverse Device Effect and procedure related Serious Adverse Events.
Incidence of significant adverse events.(thromboembolic event,hemorrhagic event)
Physical finding.
Incidence or worsening of neurologic signs/symptoms, as measured by NIHSS.

Secondary Effectiveness

Study Success Criteria
Overall study success will be met if both the primary efficacy and primary safety endpoints are met.

In outcomes field, the entry of just a few words such as "safety" or "efficiency" will not be accepted. Specify the name of outcome measures, including the time when you plan to measure. Usually, only one primary outcome is accepted. Write the other outcomes in "secondary outcomes" field.

Purpose of intervention Treatment
Type of intervention
Interventions/Control_1 (1)Gain vascular access according to standard angiographic practice.(2)Place appropriate size guidecatheter according to standard practice.(3)Coaxially navigate a microcatheter (TCD-H) over a guidewire to the aneurysm neck or target location.(4)Select an appropriate-sized TCD-14139 system.(5)Advance the delivery wire to transfer the TCD-14139 system from within the introducer into the microcatheter.(6)Position the TCD-14139 system for deployment by aligning the TCD-14139 system implant distal radiopaque end markers past the aneurysm neck.(7)Carefully inspect the deployed TCD-14139 implant under fluoroscopy to confirm that it is completely apposed to the vessel wall and not kinked. If the implant is not fully apposed or is kinked, consider utilizing a suitable microguidewire and/or occlusion balloon catheter to fully open the implant.
(8)After completing the procedure, withdraw and discard all applicable accessory devices.

In interventions field, include the details of interventions, such as duration, amount, and frequency. If the intervention includes prescription or use of medical devices, duration is required.

provides a signed informed consent form;
(3)Negative pregnancy test in a female subject.
(4)Subject commits to return to the investigational site for the 30-day, 6-month, and 12-month follow-up evaluations.
(5)Subject has a single target aneurysm located in the following zones:
- Petrous through superior hypophyseal segments of the ICA
- Communicating segment of the ICA through A1 or M1 segment
- Posterior Circulation
(6)(7)AND fit any of the following criteria:
Subject whose target aneurysm has a neck >=4mm or no discernible neck AND a size(maximum fundus diameter) >=10 mm OR subject has a fusiform aneurysm of any size requiring treatment OR Subject is a poor candidate for open surgical treatment because of prior surgical
procedure, comorbidities or location limiting conventional surgical options
OR Subject for whom exiting endovascular options (coiling, stent-assisted coiling) would be ineffective because the aneurysm is predisposed to recurrence due to having any of the
following characteristics:

b. Aneurysm has any of the following morphologies:
i. segmental parent artery dysplasia
ii. aneurysm neck involving > 180 degrees of parent artery circumference
iii. complex lobulations limiting stent/coiling as a treatment option
iv. neck >=4mm or dome/neck ratio>2
(8)The parent artery diameter must be 2.5-5.0mm distal/proximal to the target intracranialaneurysm;
Key exclusion criteria (1)(2)SAH in the last 60 days or intracranial hemorrhage in the last 30 days(3)Intracranial mass or currently undergoing radiation therapy for carcinoma or sarcoma of the head or neck region.(4)Symptomatic extracranial or intracranial stenosis of the parent artery(>50%) proximal to the target aneurysm;(5)Irreversible bleeding disorder.(6)Current alcohol or substance abuse.(7)uncontrolled severe hypertension
>180 mm Hg or>115 mmHg,(8)cre 3.0mg/dL;(9)Hypersensitivity to metal, such as nickel-titanium and metal jewelry.
(10)(11)Subject with contraindications or known allergies to anticoagulants or antiplatelets (aspirin, heparin, ticlopidine, clopidogrel, prasugrel or ticagrelor);Subject with documented contrast allergy, or other condition, that prohibits imaging.(12)Evidence of active infection at the time of treatment;(13)Presence of any of the unequivocal cardiac sources of embolism;
(14)Intracranial stenting procedure associated with the target aneurysm;
(15)Cerebral diagnostic angiogram that demonstrates an aneurysm that is not appropriate for endovascular treatment;(16)Subject has extracranial stenosis greater than 50% in the carotid artery of the targetaneurysm.(17)Subject has intracranial stenosis greater than 50% in the treated vessel(18)Subject has a mycotic or dissecting aneurysm.(19)Subject has a bifurcation.(20)Subject has a posterior circulation aneurysm.(21)Subjects aneurysm has significant branch exiting from dome of aneurysm.(22)Subject is harboring more than one aneurysm with both aneurysms requiring treatment at the same time.(23)Subject has an AVM in the area of the target aneurysm.
