## Abstract

A pericardial implantable cardioverter defibrillator (ICD) may be delivered to the heart through the chest wall using an ultrasound image guided catheter. The ICD may comprise a patch and wire leads which may be secured by a clam shell-like pad at a distal end and comprise a pig-tail shaped securing tail at the other end so that the ICD is firmly attached to the pericardium of a human heart. The ICD may be attached where most needed and serve as either a pacemaker or a defibrillator. In one embodiment, the ICD may emit radio frequency warning signals of heart failure sensed when pacemaker or defibrillator usage is rendered necessary.

## Claims

### Claim 1

An apparatus configured to serve as a cardiac pacemaker and/or defibrillator comprising one or more leads, wherein each of the one or more leads is configured to attach to a parietal surface but not to a visceral surface of a pericardium of a heart without entering a heart muscle.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising a controller.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the controller communicates with the one or more leads through a wired connection.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein each of the one or more leads comprises at least one coil.

### Claim 5 (depends on 4)

The apparatus of claim 4, wherein the at least one coil is arranged within a patch or wafer.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein each of the one or more leads is configured to be deployed from a needle coupled to an ultrasound imaging device.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the apparatus comprises a single lead.

### Claim 8 (depends on 1)

The apparatus of claim 1, wherein the apparatus comprises more than one lead.

### Claim 9 (depends on 1)

The apparatus of claim 1, wherein the apparatus comprises a harnessing member.

### Claim 10 (depends on 1)

The apparatus of claim 1, wherein the harnessing member comprises a spiraled wire.

### Claim 11

A method for implanting an apparatus configured to serve as a cardiac pacemaker and/or defibrillator, the method comprising: implanting an apparatus configured to serve as a cardiac pacemaker and/or defibrillator, wherein one or more leads of the apparatus are attached to a parietal surface but not to a visceral surface of a pericardium of a heart without entering a heart muscle.

### Claim 12 (depends on 11)

The method of claim 11, wherein implanting is accomplished by deploying the apparatus from within a needle coupled to an ultrasound imaging device.

### Claim 13 (depends on 11)

The method of claim 11, wherein the method further comprising connecting the one or more leads to a controller.

### Claim 14 (depends on 13)

The method of claim 13, wherein the connection is a wired connection.

### Claim 15 (depends on 13)

The method of claim 13, wherein the method further comprises implanting the controller.

### Claim 16 (depends on 15)

The method of claim 15, wherein the controller is implanted subcutaneously between ribs of a subject.

### Claim 17 (depends on 11)

The method of claim 11, wherein each of the one or more leads comprises at least one coil.

### Claim 18 (depends on 17)

The method of claim 17, wherein the at least one coil is arranged within a patch or wafer.
