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.

1 . (canceled) 
     
     
         2 . A method for implanting an assist device into a mammal, wherein said method comprises inserting a pump having a pump inflow and a pump outflow into a position, wherein said pump inflow is located within a first compartment in the cardiovascular system of said mammal, said pump outflow is within a second compartment in said cardiovascular system, and said pump passing from said first compartment into said second compartment. 
     
     
         3 . The method of  claim 2 , wherein said pump comprises a tubular core. 
     
     
         4 . The method of  claim 2 , wherein said mammal is a human. 
     
     
         5 . The method of  claim 2 , wherein said first compartment is the aorta and said second compartment is the left atrium. 
     
     
         6 . An assist device for improving blood flow in a mammal, wherein said cardiac assist device comprises a pump having a pump inflow and a pump outflow, wherein said pump inflow is adapted to be positioned within a first compartment in the cardiovascular system of said mammal, said pump outflow is adapted to be positioned within a second compartment in said cardiovascular system, and wherein said pump is configured to pass from said first compartment into said second compartment. 
     
     
         7 . The device of  claim 6 , wherein said mammal is a human. 
     
     
         8 . The device of  claim 6 , wherein said pump comprises a tubular core. 
     
     
         9 . The device of  claim 6 , wherein said first compartment is the aorta and said second compartment is the left atrium.
