Abstract

A catheter-based system for percutaneously supporting and articulating a septal wall of a heart includes a catheter and a flanged device. The flanged device includes a distal anchor and a proximal anchor, and has a radially collapsed configuration and a radially expanded configuration. When the flanged device is in the radially expanded configuration and disposed through a transseptal puncture in the septal wall, the flanged device is configured to anchor to the septal wall to permit manipulation thereof whereby an angle between an axis through the transseptal puncture and an axis through a native valve is reduced. The proximal anchor and the distal anchor may each be self-expanding or balloon expandable. The flanged device may further include a flanged device shaft. The flanged device shaft may be releasably coupled to the catheter.

First claim

What is claimed is:

1. A method of delivering, positioning, and articulating a flanged device for percutaneously supporting and manipulating or articulating a septal wall of a heart, the method comprising the steps of:
advancing a distal anchor of a catheter-based system through a transseptal puncture in the septal wall of the heart, wherein the catheter-based system includes a catheter and a flanged device;
transitioning the distal anchor from a collapsed state to an expanded state;
retracting the catheter-based system such that a proximal surface of the distal anchor is adjacent to and engages with the septal wall within a first chamber of the heart and a proximal anchor of the flanged device is positioned within a second chamber of the heart;
transitioning the proximal anchor from a collapsed state to an expanded state, such that the flanged device is in an expanded configuration and is anchored to the septal wall;
advancing the catheter-based system such that the flanged device manipulates or articulates the septal wall to deform the septal wall;
advancing an auxiliary medical device through the catheter-based system to treat a native heart valve;
retracting the auxiliary medical device from the catheter-based system; and
retracting the catheter-based system to permit the septal wall to return to a native shape or orientation.

2. The method of claim 1 , wherein the distal anchor and the proximal anchor of the flanged device are each self-expanding.

3. The method of claim 1 , wherein the distal anchor is a distal anchor balloon and the proximal anchor is a proximal anchor balloon, and the steps of transitioning the distal anchor from the collapsed state to the expanded state and the proximal anchor form the collapsed state to the expanded state includes inflating the distal anchor balloon from the collapsed state to the expanded state and inflating the proximal anchor balloon from the collapsed state to the expanded state.

4. The method of claim 1 , wherein the flanged device is removably coupled to the catheter and further comprising the step of:
uncoupling the catheter from the flanged device.

5. The method of claim 1 , wherein the catheter of the catheter-based system further includes an outer sheath, and the step of transitioning the distal anchor from the collapsed state to the expanded state includes first retracting the outer sheath of the catheter to release the distal anchor of the flanged device within the first chamber of the heart, and the step of transitioning the proximal anchor from the collapsed state to the expanded state includes first retracting the outer sheath of the catheter to release the proximal anchor of the flanged device within the second chamber of the heart.

6. The method of claim 1 , further comprising the steps of:
transitioning the proximal anchor from the expanded state to the collapsed state; and
transitioning the distal anchor from the expanded state to the collapsed state.
