Embodiment Construction

[0032] The present technology generally relates to hydraulic delivery systems and related methods having shunt devices for delivering medical devices. Reference in this article Figure 1-13 Specific details of several embodiments of the present technology are described. Although many embodiments are described with respect to devices, systems, and methods for delivering a prosthetic heart valve device to a native mitral valve, other applications and other embodiments than those described herein are also within the invention within the scope of technology. For example, at least some embodiments of the present technology may be used to deliver prostheses to other valves, such as tricuspid or aortic valves. It should be noted that in addition to the embodiments disclosed herein, other embodiments are within the scope of the present technology. Furthermore, those of ordinary skill in the art will appreciate that embodiments of the present technology may have configurations, comp...

Abstract

A flow diversion device configured in accordance with embodiments of the present technology may include, for example, a housing including openings to channels that intersect at a junction. The flow diversion device may also include, for example, a flow control component disposed at the junction and movable to selectively form pathways for fluid communication based on a position of the flow control component. For example, when the flow control component is in a first position, a first pathway may allow fluid flow causing deployment of the prosthetic heart valve device and, when the flow control component is in a second position, a second pathway may allow fluid flow causing recapture of the prosthetic heart valve device. The flow diversion device may include a handle movable to position the flow control component in the first or second positions thereby selectively controlling fluid flow of the delivery system.

Description

[0001] This application claims the benefit of US Provisional Patent Application No. 62 / 807,681, filed February 19, 2019, the entire contents of which are incorporated herein by reference. technical field [0002] The present technology generally relates to devices and systems for delivering medical devices into a patient. In particular, several embodiments of the present technology relate to hydraulic delivery systems and related methods having shunt devices for deploying prosthetic heart valve devices. Background technique [0003] Heart valves can be affected by a variety of conditions. For example, the mitral valve can be affected by mitral regurgitation, mitral valve prolapse, and mitral stenosis. Mitral regurgitation is the abnormal leakage of blood from the left ventricle into the left atrium caused by a cardiac condition in which the leaflets of the mitral valve fail to apposition and coapt at peak systolic pressure. The mitral valve leaflets may fail to coaptize ad...
