Abstract

This invention describes apical access methods and devices that enable repair, modification, removal, and/or replacement of a defective heart valve while allowing the beating heart to deliver blood flow through the defective valve annulus for an extended period of time in volumes sufficient to sustain life. The invention is comprised of a flow housing having a blood inflow opening, a blood outflow opening, and a one-way valve disposed within the flow housing between the inflow and outflow openings.

Claims

1. A device for allowing temporary flow control of a patient'"'"'s heart comprising a flow housing having at least one blood inflow opening, at least one blood outflow opening, and a one-way valve disposed within the flow housing between the inflow and outflow openings.

2. A method for allowing temporary flow control of a patient'"'"'s heart, comprising the steps of:

a) providing a flow housing having at least one blood inflow opening, at least one blood outflow opening, and a one-way valve disposed within the flow housing between the inflow and outflow openings;

b) making an incision in the heart adjacent one of the left and right ventricles;

c) inserting the flow housing within the incision such that within the one ventricle is located an inflow opening and the outflow opening is located within the outflow artery associated with the one ventricle.

3. A method for allowing temporary flow control of a patient'"'"'s heart, comprising the steps of:

a) providing a flow housing having at least one blood inflow opening, at least one blood outflow opening, and a one-way valve disposed within the flow housing between the inflow and outflow openings;

b) making an incision in the heart adjacent one of the left and right ventricles;

c) inserting the flow housing within the incision such that within the one ventricle is located an outflow opening and the inflow opening is located within the atrium or inflow artery associated with the one ventricle.
