Systems and methods for deploying a cardiac anchor
First Claim
1. A catheter for delivering and aligning a heart implant about a wall of a heart, the catheter comprising:
- an elongate catheter body having a cylindrical wall and a lumen disposed there through;
a handle mechanism disposed at a proximal end of the elongate catheter body;
a channel formed within the cylindrical wall on a distal end of the elongate catheter body, the channel being configured to receive the heart implant such that at least a portion of the heart implant is exposed to an interior region of the heart; and
a cable positioned within the lumen of the elongate catheter body, the cable being releasably coupled with the heart implant positioned within the channel and being operationally coupled with the handle mechanism so that a first operation of the handle mechanism causes the cable to flex outward from the channel and thereby cause at least part of the heart implant to move outward from the channel;
wherein the cable is retractable within the lumen of the elongate body and through the channel so that a distal tip of the cable is positionable proximally of a proximal end of the channel.

Abstract
A heart implant alignment and delivery device includes an elongate body having an opening that is disposed near a distal end of the elongate body. The opening is configured so that a heart implant is positionable within the opening with the heart implant exposed to a surrounding environment and so that the heart implant is substantially aligned with the distal end of the elongate body. The device also includes an implant reposition member, such as a cable, that is releasably coupleable with the heart implant and that is operationally coupled with the elongate body so that a first operation of the implant reposition member causes the heart implant to be retractably deployed from the opening of the elongate body. The first operation of the implant reposition member may be effected via a handle mechanism that is attached to a proximal end of the elongate body.

9. A heart implant alignment and delivery device comprising:
-
an elongate body having a cylindrical wall; an opening in the elongate body that is formed in the cylindrical wall and disposed near a distal end of the elongate body, the opening being configured such that a heart implant is positionable within the opening so that the heart implant is exposed to a surrounding environment and so that the heart implant is substantially aligned with the distal end of the elongate body; and an implant reposition member that is releasably coupleable with the heart implant and that is operationally coupled with the elongate body such that a first operation of the implant reposition member causes the heart implant to be retractably deployed from the opening of the elongate body; wherein the implant reposition member is retractable within a lumen of the elongate body and through the opening so that a distal end of the implant reposition member is positioned proximally of a proximal end of the opening. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of deploying a heart implant from a catheter that includes an elongate body having a cylindrical wall, a lumen disposed through the cylindrical wall, and a channel formed in the cylindrical wall, a cable disposed within the lumen, a handle mechanism disposed at a proximal end of the elongate body, and the heart implant positioned within the channel, the method comprising:
-
positioning a distal end of the elongate body within a chamber of a heart so that the channel and heart implant are adjacent a wall of the heart; and performing a first operation via the handle mechanism to cause the cable to flex outward from the channel of the elongate body and thereby cause the heart implant to pivot out of the channel of the elongate body and into contact with the wall; wherein the heart implant is retractable within the channel to enable repositioning of the elongate body within the heart and thereby ensure a proper alignment of the heart implant relative to the wall of the heart; and wherein the cable is retractable within the lumen of the elongate body and through the channel so that a distal tip of the cable is positioned proximally of a proximal end of the channel. - View Dependent Claims (16, 17, 18, 19, 20)
