Abstract

An apparatus includes a shaft, and a guide coupled and angularly deflectable relative to the shaft via a guide coupler. The guide is configured to be transitioned between a delivery configuration and a deployed configuration in which a distal end of the guide points away from a centerline of the shaft. The apparatus further includes an elongate member slidably disposable within a guide lumen and extendable distally relative to the distal end of the guide. The elongate member defines a lumen. A puncture member is slidably disposable elongate member lumen and configured to extend distally relative to a distal end of the elongate member. The puncture member defines a lumen configured to receive a guide wire, and has a first internal diameter at a distal end portion thereof and a second internal diameter, greater than the first internal diameter, in a portion proximal to the distal end portion.

Dependent claims

A method, comprising:

inserting about a guide wire, into a heart of a patient, a shaft having a guide attached thereto via a guide coupler, such that a distal end of the guide is disposed in a right atrium of the heart, the guidewire being disposed within a septum penetrator that is disposed within the guide;
with the distal end of the guide disposed in the right atrium, withdrawing the guide wire proximally such that a distal end of the guidewire is disposed within the guide;
deflecting the guide about the guide coupler such that the distal end of the guide points towards a septum of the heart;
extending an elongate member that is disposed within the guide distally from the guide and towards the septum, the elongate member having an end effector extending from its distal end;
with the elongate member extended distally from the guide, extending a septum penetrator that is slidably disposed within the elongate member distally from the elongate member such that the septum penetrator pierces the septum at a target puncture site of the septum;
and
with the septum penetrator disposed in the left atrium, extending distally the guide wire from within the septum penetrator and into the left atrium.
