Embodiment Construction

[0058] The present invention attempts to overcome the disadvantages associated with traditional open heart surgery, while also employing some of the newer techniques to reduce the duration of the treatment procedure. It is primarily intended to deliver and implant the prosthetic heart valve of the present invention by using conventional surgical techniques including the aforementioned open heart surgery. There are many approaches in this type of procedure, all of which result in the creation of direct access to the annulus of a particular heart valve. For clarity, a direct access pathway is one that allows direct (ie, macroscopic) visualization of the heart valve annulus. Additionally, it should be appreciated that the embodiments of the prosthetic heart valves described herein may also be configured for delivery using percutaneous approaches, as well as those minimally invasive surgical approaches that require remote implantation of the valve using indirect visualization. Ho...

Abstract

A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve may include a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A system and method for deployment includes an integrated handle shaft and balloon catheter. A safety member disposed between the balloon catheter and handle shaft prevents premature catheter advancement prior to heart valve placement at the annulus, and also may prevent premature balloon inflation prior to full catheter advancement.

Description

technical field [0001] The present invention generally relates to prosthetic valves for implantation in human passageways. More specifically, the present invention relates to integral surgical prosthetic heart valves and associated valve delivery systems configured to be surgically implanted in less time than current valve implantation times. Background technique [0002] In vertebrates, the heart is a hollow muscular organ with four pumping chambers, the left and right atria and the left and right ventricles, each provided with its own one-way valve. The natural heart valves are considered to be the aortic, mitral (or bicuspid), tricuspid, and pulmonary valves, and each valve is seated in an annulus that either directly or Indirectly attached to the dense fibrous rings of atrial and ventricular muscle fibers. Each annulus defines a flow port. [0003] The atria are the blood receiving chambers that pump blood to the ventricles. The ventricles are the chambers that drain...
