Abstract

An annuloplasty device having an expandable member, a plurality of lobes, and a piercing wire is herein disclosed. In some embodiments, the lobes extend radially outwardly from the expandable member. The lobes each have a wire lumen disposed therethrough, and the piercing wire is extendable through the wire lumen of each lobe to secure the device to adjacent heart tissue. In some embodiments, the expandable member comprises an inflatable medical balloon. In addition, a method of implanting an annuloplasty device is disclosed.

Claims

1. An annuloplasty device comprising:

an expandable member comprising an expandable balloon, the expandable balloon including a plurality of ports;

a plurality of lobes extending radially from the expandable member, each lobe having a wire lumen disposed therethrough; and

a piercing wire, the piercing wire extendable through the wire lumen of each lobe;

wherein each port extends between the expandable balloon and one of the lobes.

2. The annuloplasty device of claim 1, wherein the expandable member defines a guidewire lumen extending through the expandable member.

3. The annuloplasty device of claim 1, wherein the piercing wire is biased in a semi-circular shape.

4. The annuloplasty device of claim 1, wherein the lobes are attached to the expandable member with an adhesive.

5. The annuloplasty device of claim 1, wherein the piercing wire comprises two segments, the two segments coupled together via a coupler.

6. The annuloplasty device of claim 1, wherein the plurality of lobes includes a distal most lobe and a proximal most lobe, a portion of the piercing wire being secured to the distal most lobe upon insertion of the piercing wire into the distal most lobe.

7. The annuloplasty device of claim 6, wherein a portion of the piercing wire is secured to the proximal most lobe upon insertion of the piercing wire into the proximal most lobe.
