Example Embodiment

[0054] In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details in order to provide a thorough understanding of the embodiments. However, to those skilled in the art readily appreciate that the present invention may be practiced without the specific details. Furthermore, embodiments may be omitted or simplified in order not to obscure well known features described.

[0055] Reference now figure 1 The principles of the present invention configured as heart assist system 10 may include a cardiac assist catheter 12 and the external drive unit 14. Cardiac assist catheter 12 typically comprises a catheter body 18, the catheter body 18 having a balloon located at a distal end portion 20 or other pneumatic actuators. The implantable port 24 connected to the proximal end of the catheter body 18, and the body has a distal tip 26 typically, the distal tip 26 having a guidewire lumen defined...

Abstract

A cardiac assist system includes a pneumatic effector which is implanted beneath a pericardial sac and over a myocardial surface overlying the patient's left ventricle. A port is implanted and receives a percutaneously introduced cannula. The port is connected to supply a driving gas received from the cannula to the pneumatic effector. An external drive unit includes a pump assembly and control circuitry which operate the pump to actuate the pneumatic effector in response to the patient's sensed heart rhythm. A connecting tube has a pump end connected to the pump and a percutaneous port-connecting end attached to the implantable port.

Description

[0001] Cross-reference related application [0002] This application claims the February 26, 2019, filed the benefit of US Provisional Patent 62 / 810,866 (Attorney Docket No. 56027-703.101), the entire contents of which are incorporated herein by reference. Background technique [0003] 1. Field. The present invention generally relates to medical devices, systems and methods. More particularly, the present invention relates to a system for providing assistance to cardiac patients with advanced heart failure. [0004] A variety of ventricular assist devices (VAD) is used to support patients with severe heart failure of blood circulation it has been proposed. VAD is also used to make the patient alive until a donor heart can be used for transplantation, as a "bridge to transplant." In the US, end-stage heart failure each year as many as 50,000 patients need a heart transplant. Donor heart can only be used every year 2,000 to 2,500 patients. Many patients can not receive a transplan...
