## Abstract

This document relates to materials and methods for circulatory bypass of a ventricle in the heart of a mammal. For example, materials and methods for bypassing a permanently or temporarily impaired left ventricle in the heart of a mammal (e.g., a human) are provided.

## Claims

### Claim 1

A ventricular assist device for improving blood flow in a human, wherein said ventricular assist device is adapted to be positioned across a shared wall between an aorta and left atrium of said human and comprises:
(a) a conduit, wherein said conduit comprises a proximal region, a distal region and an intermediate region located between said proximal and distal regions, wherein said proximal region is adapted to be positioned within said aorta, and said distal region is adapted to be positioned within said left atrium, and wherein said intermediate region defines a lumen through said shared wall, and
(b) a pump comprising an inflow and an outflow, wherein said pump is adapted to be positioned within said conduit, and wherein the distance between said inflow and said outflow is the thickness of said shared wall.

### Claim 2 (depends on 1)

The device of claim 1, wherein said conduit is constructed of expandable or malleable material.

### Claim 3 (depends on 2)

The device of claim 2, wherein said malleable material is nitinol.

### Claim 4 (depends on 1)

The device of claim 1, wherein said proximal region and said distal region are independently adjustable.

### Claim 5 (depends on 1)

The device of claim 1, wherein said intermediate region comprises a tubular core.

### Claim 6 (depends on 5)

The device of claim 5, wherein said tubular core comprises a septum or valve.

### Claim 7 (depends on 1)

The device of claim 1, wherein said ventricular assist device comprises electrodes.
