Description of intervention(s) / exposure
an electrophysiologist will insert the transseptal introducer sheath and dilator assembly into the vein over a standard guidewire and advanced until the sheath tip is in the SVC. A transseptal needle is flushed as in normal standard of care and inserted into the sheath assembly once an appropriate angle is set under fluoroscopy with the access path. The access path assists by setting the angle to cross the septum. The transseptal needle is then pushed across the interatrial septum under fluoroscopy. This use is no different from normal standard of care for transseptal access.

Outcomes
Primary outcome [1] 319162 0
Use of the Access Path sheath during catheter based treatment of atrial fibrillation by ablation and complete the procedure with no adverse device or procedure events at completion of procedure and discharge per per institutional standard of care. Adverse events such as access groin hematomas or excessive bleeding events and will be tracked using data case report forms collected post procedurally and until discharge measured by safe event free completion of the procedure and removal of the device. Data will be monitored for accuracy and reported in a investigational summary report.
Timepoint [1] 319162 0
intra procedure, post procedure and discharge
Primary outcome [2] 319163 0
Insertion of the transseptal introducer sheath to assist in selecting the location in the septum to cross under fluoroscopy. Introducer sheath will be used no more than two times to achieve and reach a successful performance outcome. This data will be collected on study approved data case report forms and source documentation will include fluoro images collected post procedurally from the investigator.
Timepoint [2] 319163 0
Intraprocedure
Secondary outcome [1] 367148 0
ability to visualize the sheath for precise positioning under fluoroscopy and images stored as source documentation as well as data case report forms collected from the study coordinator.
Timepoint [1] 367148 0
intraprocedure only
Secondary outcome [2] 367320 0
ability to advance the sheath across the fossa ovalis under fluoroscopic guidance. Images will be collected post procedure as source data and stored. Data results input on data case report forms filled out by the study coordinator.
Timepoint [2] 367320 0
Intraprocedure
Secondary outcome [3] 367321 0
safe free insertion of the sheath under fluoroscopic guidance. Confirmation will be saved by images stored post procedure and collected on data case report forms from the study coordinator.
Timepoint [3] 367321 0
intraprocedural and discharge
Secondary outcome [4] 367788 0
safe free retrieval of the sheath out of the body under fluoroscopic guidance. Images of this under fluoroscopy will be stored as source data. Data will also be collected on case report forms post procedure filled out by the study coordinator.
Timepoint [4] 367788 0

Statistical methods / analysis
The safety and performance of the device will be assessed relative to the study objectives. All study results will be analyzed using widely accepted statistical or graphical software. Data will be evaluated to published literature on currently available steerable sheaths. No statistical analysis will be performed on this small sample size.
