The objective of this study is to determine the safety, performance, and effectiveness of the SeptRx IPO PFO Closure System in the treatment of Patent Foramen Ovale (PFO) in patients who are amenable to percutaneous closure of their PFO defects.

Condition Intervention
Foramen Ovale, Patent Heart Defects, Congenital Heart Septal Defects Device: Transcatheter PFO closure with the SeptRx Intrapocket PFO Occluder (IPO)

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: InterSEPT: In‐Tunnel SeptRx European PFO Trial: A Prospective, Multi‐Center Study to Evaluate the Safety and Performance of the SeptRx IPO PFO Closure System

Further study details as provided by SeptRx, Inc.:

Primary Outcome Measures:
  • Safety: Major Adverse Events defined as composite rate of all death, stroke, device embolization, tamponade, and device related re‐intervention or surgery [ Time Frame: One (1) month ]

Secondary Outcome Measures:
  • Efficacy: Device success defined as PFO closure at 6 months post procedure by transesophageal echocardiography (TEE) with contrast valsalva bubble study. [ Time Frame: Six (6) months ]

Estimated Enrollment: 70
Study Start Date: June 2011
Estimated Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
