Study Type

INTERVENTIONAL

Conditions

Intracranial Aneurysm

Summary

This is an investigational study for a new medical device called the nOCT (neuro optical coherence tomography) Imaging System, which is manufactured by Spryte Medical, LLC. The nOCT Imaging System takes pictures from inside a blood vessel in your brain. These pictures give your doctor information about the inside of your blood vessel including the disease and any implanted devices. The nOCT Imaging System consists of a probe and a console. The probe is a small, flexible wire-like device designed to navigate through catheters which have already been inserted in your body as part of your planned procedure. Catheters are small, flexible, tubes inserted in your blood vessels which allow your doctor to deliver treatments such as medications, coils, or stents directly to the affected area. The console is a unit that includes a computer, screen and laser light source. The probe is connected to the console. The console provides the probe with low-power light from the laser which is used to scan and create pictures of your blood vessel. The pictures are displayed on the screen of the console for review by your doctor and may be stored for future viewing. The objective of the study is to evaluate the safety and effectiveness of the nOCT Imaging System to provide quality images for diagnostic assessment during endovascular intracranial aneurysm treatment and follow-up.

Eligibility

Min Age: 18 YearsMax Age: 75 Years

Inclusion Criteria5

Subject age ≥ 18 and ≤ 75 years
Subject has a pre-procedure mRS ≤ 3
Subject is undergoing a planned treatment for an intracranial aneurysm, unruptured or ruptured
Subject understands the investigational procedure, consents to participation, is willing to comply with study follow-up requirements and provides a signed informed consent document
Parent artery has a diameter ≥ 1.3 mm and ≤ 6.0 mm as measured by angiography.

Exclusion Criteria17

Subjects with a minimum platelet count of < 100,000/μL.
Subjects who have suffered an ischemic stroke or transient ischemic attack within the past 30 days.
Subject has an acutely ruptured aneurysm with a Hunt \& Hess score ≥ 4
Subject has an infectious, blister-like, fusiform, dissecting, traumatic or mycotic aneurysm confirmed by angiography
Subject has challenging anatomy that in the investigator's opinion is not suitable for safe delivery of an 0.021" catheter, including stenosis > 70% or excessive tortuosity
Subject presents with other medical or surgical co-morbidities limiting his/her life expectancy to less than one year
Subject is, in the opinion of the investigator, unlikely to comply with the study protocol or follow-up requirements.
Subject with any condition which in the opinion of the treating physician would place the subject at an elevated risk of embolic stroke
Subject with known allergy or other contraindication to heparin, iodinated contrast, or dual-antiplatelet medication
Subject has ipsilateral carotid or vertebral artery stenosis greater than 50%
Subject underwent stenting, angioplasty, or endarterectomy procedures of an extracranial (carotid or vertebral artery) or intracranial artery within 30 days prior to treatment.
Subject has serious concurrent medical conditions including bacteremia or sepsis, acute renal failure at the time of the procedure, and major coagulation system abnormalities that in the opinion of the investigator could significantly increase risk
Subject has severe intracranial vasospasm not responsive to medical therapy
Subject has chronic kidney disease stage ≥ 4 and is not undergoing dialysis
The subject is pregnant or breastfeeding at the time of admission or plans to become pregnant during their participation in the trial
Subject is currently participating in another clinical research trial involving an investigational device or drug
Subject is under judicial protection or legal guardianship

Interventions

PROCEDUREEndovascular Intracranial aneurysm treatment

Endovascular Intracranial aneurysm treatment using devices such as coils, flow diverters, etc. The treatment will include devices that are all FDA approved.

DEVICEnOCT imaging

During the aneurysm treatment and during the subsequent follow-up, nOCT imaging will be performed.
