  Purpose
The objective of the GELATIN registry is to prospectively evaluate intracranial aneurysm occlusion and retreatment rates as well as adverse event rates in patients undergoing balloon-assisted coiling using the MicroVention Scepter Occlusion Balloon Catheter and second-generation MicroVention hydrogel coils for treatment of previously treated or untreated ruptured and unruptured intracranial aneurysms.

Primary Outcome Measures:
  • Aneurysm recurrence rate [ Time Frame: 3-9 month follow-up ]

Secondary Outcome Measures:
  • Occlusion Rate [ Time Frame: At immediate post-procedure (Day 1) and 3-9 month follow-up ]
    Angiographic occlusion of the aneurysm will be adjudicated using immediate post-procedure and 3-9 month follow-up angiography.

  • Number of coils used [ Time Frame: At end of study procedure (Day 1) ]
  • Total coil length used [ Time Frame: At immediate post-procedure (Day 1) ]
  • Aneurysm re-treatment rate [ Time Frame: 3-9 month follow-up ]
  • Aneurysm Bleed and Re-bleed Rate [ Time Frame: 3-9 month follow-up ]
    Aneurysm Bleed and Re-bleed Rate will be assessed and recorded at the 3-9 month follow-up.

  • Time of fluoroscopic exposure [ Time Frame: At immediate post-procedure (Day 1) ]
    Total time of fluoroscopic exposure will be captured from the initial recording of the road map to the final angiogram after completion of the coil embolization procedure.

  • Modified Rankin Score [ Time Frame: At baseline (Day 1) and hospital discharge (Day 3) and 3-9 month follow-up ]
    Modified Rankin score will be recorded at baseline, hospital discharge, and during the 3-9 month follow-up.

  • Device-related serious adverse events [ Time Frame: From the study procedure (Day 1) until 3-9 month follow up ]
    Procedural and post-procedural serious adverse events related to the device and/or procedure will be captured and recorded at the end of the procedure and until the patient has completed the 3-9 month follow-up.

Other Names:
  • MicroVention hydrogel coils
  • MicroVention Scepter C
  • MicroVention Scepter XC

Detailed Description:
This is a prospective, single arm, single center study of patients with ruptured or unruptured saccular aneurysms that are embolized using MicroVention second-generation hydrogel coils and undergo balloon remodeling with the MicroVention Scepter Occlusion Balloon Catheter. Data for each patient will be collected 6 ± 3 months post-procedure for the study.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Patient is 18-80 years of age.
  • Patient has a documented, previously treated or untreated saccular intracranial aneurysm, 4- 20 mm unruptured or ruptured, suitable for treatment with balloon assisted coil embolization.
  • Target aneurysm has a neck ≥4mm or the largest diameter to neck ratio of 2 or less.
  • Patient has a Hunt and Hess Score of 3 or less.
  • Patient has a premorbid mRS of 3 or less.
  • Patient or patient's legally authorized representative has provided written informed consent.
  • Patient is willing to and can comply with study follow-up requirements.

Exclusion Criteria:

  • Inability to obtain informed consent.
  • Patient is <18 or >80 years of age.
  • Target aneurysm is dissecting, fusiform, mycotic, or arteriovenous malformation-related.
  • Aneurysm that was treated previously with stent-assisted coiling.
  • Implantation of the stent after the balloon-assisted coiling or combined stent and balloon assisted coiling.
  • Target aneurysm is deemed unsuitable for balloon-assisted coiling by the treating physician prior to the procedure.
  • Target aneurysm will be treated with a total coil length comprised of less than 80% second generation MicroVention Hydrogel Coils.
  • Balloon-assisted coiling will be performed using a balloon catheter other than the MicroVention Scepter balloon (Scepter C, Scepter XC, any future Scepter configurations).
  • Patients in which the target aneurysm is planned not to be coiled in one procedure (i.e. staged procedure).
  • Patients with more than one aneurysm that requires treatment. (However, a second small low risk aneurysm that does not require therapy may be allowed.)
  • Patients with a life expectancy of ≤ 9 months.
