## Abstract

Devices and methods for the treatment of heart conditions, and other medical purposes, include cardiac pacing systems. For example, this document describes temporary transvenous endocardial pacemaker systems and devices for deploying such systems without the need for conventional imaging procedures.

## Claims

### Claim 1

A temporary transvenous pacemaker system, comprising:
a pulse generator;
an electrode wire coupleable to the pulse generator and including a bi-polar electrode pair at a distal tip of the electrode, the bi-polar electrode pair configured to transmit electrical pulses from the pulse generator to tissue contacting the bi-polar electrode pair; and
a patient drape device comprising:
a flexible substrate configured to cover a portion of a patient; and
a plurality of indicator lights attached to the flexible substrate, wherein each of the indicator lights actuates to two or more types of lit conditions in response to a magnetic field emanating from the distal tip, and wherein each of the plurality indicator lights can be individually selectively de-activated.

### Claim 2 (depends on 1)

The temporary transvenous pacemaker system of claim 1, wherein the distal tip includes an electromagnet configured to generate the magnetic field.

### Claim 3 (depends on 1)

The temporary transvenous pacemaker system of claim 1, wherein the pulse generator is configured to be used external to the patient.

### Claim 4 (depends on 1)

The temporary transvenous pacemaker system of claim 1, wherein the patient drape further comprises one or more electromagnets attached to the flexible substrate, wherein the one or more electromagnets can influence the positioning of the distal tip.

### Claim 5 (depends on 1)

The temporary transvenous pacemaker system of claim 1, wherein the distal tip is selectively expandable.

### Claim 6 (depends on 1)

The temporary transvenous pacemaker system of claim 1, wherein the distal tip includes anchor elements configured to engage with the tissue.

### Claim 7 (depends on 6)

The temporary transvenous pacemaker system of claim 6, wherein the anchor elements are bioabsorbable.
