## Abstract

The invention generally relates to devices and methods for treating cardiac tissue, including percutaneous closure of cardiac openings such as a patent foramen ovale (PFO) and obliteration of the cardiac cul-de-sacs. The invention includes a device having at least one elongated member. The elongated member has a first material and a second material interwoven with at least a portion of the first material. The second material is capable of transferring energy to tissue in need of treatment.

## Claims

### Claim 1

An energy transferring medical device, comprising:
one elongated member comprising a sleeve with an interior surface, wherein a portion of the sleeve is adapted to invert at a distal end of the elongated member and the interior surface of inverted portion of the sleeve forms an exterior surface of the elongated member, wherein the distal end of the elongated member includes a hairpin turn and the sleeve comprises a first substantially non-conductive material and a second energy transferring material at a portion of the sleeve, interwoven with the first substantially non-conductive material along at least a portion of the hairpin turn; and
an actuator operatively joined to the proximal end of the elongated member, wherein movement of the actuator causes rotational movement of the elongated member about a longitudinal axis of the sleeve.

### Claim 2 (depends on 1)

The device of claim 1 wherein the elongated member comprises a first position in which the portion of the elongated member comprising the second energy transferring material is located on the interior surface of the elongated member.

### Claim 3 (depends on 2)

The device of claim 2 wherein movement of the actuator in a proximal direction places the elongated member in a second position wherein the portion of the elongated member comprising the second energy transferring material is relocated to the exterior surface of the elongated member.

### Claim 4 (depends on 1)

The device of claim 1 wherein the elongated member comprises a first position in which the portion of the elongated member comprising the second energy transferring material is located on the exterior surface of the elongated member.

### Claim 5 (depends on 4)

The device of claim 4 wherein movement of the actuator in a proximal direction places the elongated member in a second position wherein the portion of elongated member comprising the second energy transferring material is relocated to the interior surface of the elongated member.

### Claim 6 (depends on 1)

The device of claim 1 wherein the second energy transferring material is selected from the group consisting of copper, gold, platinum, silver, iron, lithium, cobalt, nickel, and chromium, or a combination thereof.

### Claim 7 (depends on 1)

The device of claim 1 wherein the second energy transferring material comprises a glass or ceramic material.
