Benefits of technology

The patent is about improving methods and systems for supporting the heart's pumping action during surgery. Currently, accessing the patient's blood vessels can be complicated and uncomfortable, and can affect patient mobility. The patent proposes a solution that can replace traditional ventricular assist devices. The technical effect is better ways to support the heart without causing these complications.

Problems solved by technology

Most of these complications happen as a result of the large bore arterial access.
Additionally, successful access to the arterial vasculature may be affected by other vascular diseases.

Embodiment Construction

[0052]Specific embodiments of the disclosed device, delivery system, and method will now be described with reference to the drawings. Nothing in this detailed description is intended to imply that any particular component, feature, or step is essential to the invention.

[0053]Historically, patients who need hemodynamic support with the currently available devices for left ventricular failure require large bore arterial access. The arterial access is obtained either surgically or percutaneously by advancing a needle in an artery, threading a guidewire through the needle, and then advancing a catheter over the guidewire into the arterial system. Clinical trials have demonstrated up to 40% access site complications during hemodynamic support. Access complications may be the Achilles heel of percutaneous hemodynamic support. Currently, patients with severe peripheral artery disease have very limited options that are still associated with significant risk to the patient. Similar problems ...

Abstract

The procedure to place antegrade hemodynamic support (AHS) combine currently available procedures and devices in a unique fashion to solve a significant problem for patients who need large bore hernodynarnic support. The AHS procedure involves delivering an AHS device or a catheter connected to an AHS device to a patient's aorta in an antegrade fashion, alleviating the workload on the patient's heart and supporting the patient hemodynamically to maintain normal functions of the body organs.

Description

RELATED APPLICATIONS[0001]The present application is a continuation of U.S. patent application Ser. No. 15 / 943,477 (Attorney Docket No. 5139.001US1) filed Apr. 2, 2018, which is a non-provisional of and claims the benefit of US Provisional Patent Application Nos. 62 / 520,365 (Attorney Docket No. 5139.001PV2) filed on Jun. 15, 2017 and 62 / 481,024 (Attorney Docket No. 5139.001PRV) filed on Apr. 3, 2017; the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Patients who need hemodynamic support with currently available devices for left ventricular failure require large bore arterial access. The arterial access is obtained either surgically or percutaneously by advancing a needle in an artery, threading a guidewire through the needle, and then advancing large catheters over the wire into the arterial system.SUMMARY OF IIIE INVENTION[0003]Clinical trials have demonstrated up to 40% access site complications during hemodynamic support. Most of t...
