Direct visualization device, system and method for transseptal transection

摘要

PROBLEM TO BE SOLVED: To provide a direct visualization catheter for transseptal crossing. A direct visualization catheter 100 includes at least one outer member 110, an inner member 120, a transparent balloon member 130, and an imaging element 140, the outer member extending from a proximal end to a distal end. An elongate body including a tubular body and forming a first lumen therethrough, the inner member slidably disposed within the first lumen of the outer member, and including an elongated body having a distal end; The transparent balloon member is mounted between the distal end of the outer member and the distal end of the inner member such that its shape is adjusted by sliding the inner member and the outer member together, and the imaging element is Located within the balloon member.
