Abstract
An embodiment provides a method for normalizing cardiac venous return, including: inserting percutaneously a calibrated balloon catheter through a femoral vein; advancing the calibrated balloon catheter to the inferior vena cava; and placing a balloon portion of the calibrated balloon catheter at a location before the drainage point of the hepatic vein.
Claims10
A method for normalizing cardiac venous return, comprising:
- inserting percutaneously a calibrated balloon catheter through a femoral vein;
- advancing the calibrated balloon catheter to the inferior vena cava;
- and
- placing a balloon portion of the calibrated balloon catheter at a location before the drainage point of the hepatic vein, wherein the balloon portion of the calibrated balloon catheter comprises a smaller diameter on a proximal end as compared to a distal end.

A method for normalizing cardiac venous return, comprising:
- inserting percutaneously a calibrated balloon catheter through a femoral vein wherein the calibrated balloon catheter is calibrated to a degree of collapse during inspiration state of a patient inferior vena cava;
- advancing the calibrated balloon catheter to the inferior vena cava, wherein the calibrated balloon catheter intermittently occludes the inferior vena cava during patient inspiration;
- and
- placing a balloon portion of the calibrated balloon catheter at a location before the drainage point of the hepatic vein, wherein the balloon catheter free-floats in the inferior vena cava without an active fixation point between the balloon catheter and an inner lumen of the inferior vena cava, wherein the balloon portion of the calibrated balloon catheter comprises a smaller diameter on a proximal end as compared to a distal end.
