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.
Claims21
A ventricular assist device for improving blood flow in a mammal, wherein said ventricular assist device 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 a first compartment in the cardiovascular system of said mammal, and said distal region is adapted to be positioned within a second compartment in said cardiovascular system, and wherein said intermediate region defines a lumen through a wall between said first and second compartments, and
- (b) a pump, wherein said pump is adapted to be positioned within said conduit.
A method for treating heart disease in a mammal, said method comprising implanting an assist device within the cardiovascular system of said mammal, wherein said assist device comprises (i) 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 a first compartment in the cardiovascular system of said mammal, and said distal region is adapted to be positioned within a second compartment in said cardiovascular system, and wherein said intermediate region defines a lumen through a wall between said first and second compartments, and (ii) a pump, wherein said pump is adapted to be positioned within said conduit, under conditions wherein blood flow in said mammal is enhanced, thereby treating said heart disease.
A method for implanting an assist device into a human, wherein said method comprises
- (i) inserting a conduit having a proximal region, a distal region, and an intermediate region located between said proximal and distal regions into a position wherein said proximal region is located within the aorta of said human, said distal region is located within the left atrium of said human, and said intermediate region defines a lumen through the shared wall between said aorta and left atrium, and
- (ii) inserting a pump into said conduit such that blood is pumped through said conduit from said left atrium to said aorta.
