Percutaneous right ventricular assist apparatus and method
First Claim
1. A method for assisting the heart of a patient comprising the steps of:
- inserting a pulmonary artery (PA) cannula into the right internal jugular vein of the patient;
moving the PA cannula in the vasculature and into the PA of the patient via an anatomical pathway through the right heart;
inserting a right atria (RA) cannula into the a peripheral vein of the patient;
moving the RA cannula in the vasculature and into the RA of the patient, so that the right ventricle of the patient is bypassed;
connecting the RA cannula and the PA cannula to a blood pump disposed outside of the patient, with the RA cannula connected to an inlet of the blood pump and the PA cannula connected to an outlet of the blood pump; and
activating the blood pump to provide only right ventricular assist to the heart of the patient and without open heart surgery or left ventricle support.

Abstract
A system for assisting the right heart of a patient includes a PA cannula adapted for insertion into a PA of a patient through the right internal jugular vein of the patient. The system includes a percutaneous RA cannula adapted for insertion into an RA of the patient. The system includes a blood pump disposed outside of the patient to which the RA cannula and the PA cannula are connected to provide right ventricular circulatory support to the patient without any left ventricular assist. A method for assisting the right heart of a patient includes the steps of inserting a PA cannula into a PA of a patient. There is the step of inserting an RA cannula into an RA of the patient. There is the step of connecting the RA cannula and the PA cannula to a blood pump disposed outside of the patient. There is the step of activating the blood pump to provide right ventricular circulatory support to assist the heart of the patient.

16. A closed chest system for assisting the right heart of a patient comprising:
-
a pulmonary artery (PA) cannula adapted for insertion into the right internal jugular vein of the patient and to extend into the PA of the patient via an anatomical pathway through the right heart; a percutaneous right atria (RA) cannula adapted for insertion into a peripheral vein of the patient and to extend into the RA of the patient, so that the right ventricle of the patient is bypassed; and a blood pump disposed outside of the patient, the blood pump comprising an inlet connected to the RA cannula and an outlet connected to the PA cannula for providing only right ventricular circulatory support to the patient without open heart surgery or left ventricle support. - View Dependent Claims (17, 18, 19, 20)
