The primary objective of this study is to collect data regarding the effectiveness of using the Enterprise 2 Reconstruction Device in successfully embolizing intracranial aneurysms with wide neck configuration.
The Codman Enterprise 2 Vascular Reconstruction Device is a self-expanding nitinol, compliant, closed-cell, recapturable design that can be deployed by a single operator. The Codman Enterprise 2 Vascular Reconstruction Device is packaged sterile as a single unit with an introducer sheath and a detachable push wire.
This device was designed to assist in the stent-assisted coil embolization of intracranial aneurysms, specifically those that have a wide neck that would not otherwise maintain the coil embolization material within the aneurysm because of the wide opening at the base of the aneurysm. The Codman Enterprise 2 Vascular Reconstruction Device is approved by the FDA as a Humanitarian Use Device (HUD) in cases of wide-necked saccular cerebral aneurysms.
The primary objective of this study is to collect data regarding the effectiveness of using the Enterprise 2 Reconstruction Device in successfully embolizing intracranial aneurysms with wide neck configuration. Secondly, to determine any safety or delivery problems that may occur, or any adverse patient events that may have previously been undocumented.

| Codman Enterprise 2 Vascular Reconstruction Device | Device | a self-expanding nitinol, compliant, closed-cell, recapturable design that can be deployed by a single operator designed to assist in the stent-assisted coil embolization of intracranial aneurysms, specifically those that have a wide neck that would not otherwise maintain the coil embolization material within the aneurysm because of the wide opening at the base of the aneurysm. |
| Measure | Description | Time Frame |
|---|---|---|
| Device Effectiveness-Stent Migration | Prior Observation studies have noted in other stents, that over time, a stent may migrate from its original location, given the flow dynamics and potentially from stent under-sizing. This could potentially disrupt flow through the artery, or even uncover the aneurysm, openining, potentially allowing outflow of embolization coils. | Patients will be followed for a minimum period of 2 years from the date of the procedure, with planned total duration of 4 years of the study, including follow-up time. |
| Device Effectiveness- Stent Fore-shortening | If a stent contracts slightly after placement, then it could shorten slightly, particularly if the stent is placed around a tortous corner. In this type of event, generally there is no significant impact to the patient, unless the stent were to shorten and uncover the opening of the aneurysm, potentially allowing embolization coils to come out of the aneurysm. | Patients will be followed for a minimum period of 2 years from the date of the procedure, with planned total duration of 4 years of the study, including follow-up time. |
| Device Effectiveness- In-stent stenosis | In this known phenomenon with stents, it is possible that either through local inflammatory reaction or by hyper neointimalization, there can be a buildup of materila on the inner lumen of any stent that is placed. | Patients will be followed for a minimum period of 2 years from the date of the procedure, with planned total duration of 4 years of the study, including follow-up time. |
