Device allowing large bore transseptal access with subsequent atrial re-access and method thereof

Abstract

The present disclosure relates to medical devices. More particularly, this disclosure describes a vascular device allowing large bore transseptal access with subsequent atrial re-access by preplacing closures/tissue approximating sutures prior to creating a septostomy. Generally, the device may include a delivery catheter for puncturing and cutting the interatrial septum. An anchor of the delivery catheter may secure the suture in an atrium to a septum wall, for example, the left atrium. Incisions may be made by an expandable cutting implement which may use mechanical or radio frequency (RF) energy without interfering with the suture. A therapeutic instrument may be advanced through the tissue plane after the incisions are made by the cutting implement. Closure of the incision may be performed with the previously placed sutures.

Dependencies are inferred from the claim text.
