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.

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.

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.

Brief summary
Participants in this study will have an abnormal heart rhythm called paroxysmal atrial fibrillation. They will be
scheduled for an ablation to try to control this rhythm. All participants will have this scheduled as part of their clinical
management as discussed with their cardiologist.
To perform this procedure the cardiologist needs to put a small catheter into the left upper chamber of the heart. The
catheter is inserted into a vein in the leg and threaded into the top right chamber of the heart. From there a small
puncture (transseptal puncture) is made through the wall that separates the atria (top chambers) to allow access to
the left side. The AccessPath™ Transseptal Introducer Sheath System is designed to improve the precision and
safety of transseptal access in preparation for the ablation procedure by helping the doctor to more accurately
position the needle to make the puncture in the correct position.
This trial assesses the design and function of the AccessPath™ Transseptal Introducer Sheath System, which
consists of an introducer, guidewire and dilator with suction flute.
Fluoroscopy (x-rays) will be used to visually confirm positioning of the AccessPath™ Transseptal Introducer Sheath
throughout the procedure. It is usual for x-rays to be used for this procedure.
The doctor will use the AccessPath™ Transseptal Introducer Sheath System in accordance with the Instructions
for Use (IFU) and follow his/her standard practice for performing an ablation procedure for atrial fibrillation. It is
expected that the AccessPath™ Transseptal Introducer Sheath System will be used as part of the procedure, with
no changes required. The doctor will then perform the necessary ablation procedure. The participant will stay in
hospital overnight and have the standard tests performed, ECG and echocardiogram (ultrasound of the heart)to rule
out any complications before being discharged.
Study participation will end on discharge from hospital.
