Abstract

The invention relates to an active introducer sheath system. Disclosed herein is an active introducer sheath system that is expanded by activating a translation mechanism at a handle. The sheath has an internal cylindrical structure of a hybrid fixed elongate bar and moving elongate bar bounded together by an attachment wire. Actuating the translation mechanism causes the moving rod to move axially relative to the fixed rod, thereby changing internal tension in the attachment wire. The increased tension pulls the fixed rod and the movable rod together, so that the diameter of the cylindrical structure is reduced. The reduced tension in the attachment line moves the fixed rod and the moving rod apart, thereby increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, may pass through the expanded sheath and reach an implantation site. During implantation, the sheath may contract back to its original outer diameter and expand again to remove the delivery device.

Description

[0001] This application is a divisional application of a patent application with an application date of August 28, 2018 and an application number of 2018800657293, entitled "Active Introducer Sheath System". [0002] CROSS-REFERENCE TO RELATED APPLICATIONS [0003] This application claims the benefit of US Provisional Application No. 62 / 552,609, filed August 31, 2017, which is incorporated by reference in its entirety for all purposes. technical field [0004] This application relates to active introducer sheath systems for use with catheter-based techniques for repairing and / or replacing heart valves and for delivering implants such as prosthetic valves to the heart via a patient's vasculature use. Background technique [0005] Intravascular delivery catheter assemblies are used to implant prosthetic devices, such as prosthetic valves, within the body at locations that are not easily accessible surgically or where non-invasive surgical access may be desired. For example, ...
