An interventional study of LuSeed Aneurysm Embolization System in Aneurysm Cerebral, Bifurcation and Unruptured Intracranial Aneurysm, sponsored by LuSeed Vascular LTD.. Not yet recruiting at 1 site in Canada. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2025-12-09.
Sponsored by LuSeed Vascular LTD. · Not applicable, Interventional, and Device feasibility
The primary objective of this clinical investigation is to evaluate the early safety and feasibility of the LuSeed Aneurysm Embolization System for treating unruptured intracranial aneurysms (IA). This is a single-arm, open-label, single-center, interventional study, screening patients approved for treatment of unruptured IAs based on national or international guidelines. Up to 10 eligible subjects meeting inclusion and exclusion criteria and providing consent will be enrolled in a Canadian site.
LuSeed Vascular will sponsor the study and the study will assess early safety and feasibility of the LuSeed Aneurysm Embolization System for the treatment of unruptured intracranial aneurysms (IA).
418 studies on the registry are indexed under Intracranial Aneurysm; 119 are open to participants now.
This study's planned enrollment of 10 is below the median of 100 across 207 interventional studies indexed under Intracranial Aneurysm.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Start is estimated for Dec 2025; primary completion for Dec 2027, 24 months later.
Of 48 industry-sponsored interventional studies with no phase under Intracranial Aneurysm, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 49. This study's planned 24 months is below that.
Counting every sponsor, half of 104 studies reached it within 39 months; a quarter within 22 and three quarters within 69.
