Abstract

Disclosed herein is an active introducer sheath system that expands by activating a translation mechanism at a handle. The sheath has an internal cylindrical structure of mixed stationary elongated rods and moving elongated rods bound together by attachment wires. Activation of the translation mechanism causes the moving rod to move axially relative to the fixed rod, thereby changing the internal tension in the attachment line. The increased tension draws the fixed and moving rods closer together, reducing the diameter of the cylindrical structure. The reduced tension in the attachment wires moves the fixed and moving rods apart, thereby increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be passed through the expanded sheath and to the implantation site. During implantation, the sheath can shrink back to its original outer diameter and expand again to remove the delivery device.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] 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 [0003] This application relates to active introducer sheath systems for use with catheter-based technologies 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 [0004] Intravascular delivery catheter assemblies are used to implant prosthetic devices, such as prosthetic valves, within the body in locations that are not easily accessible surgically or where non-invasive surgical access may be desired. For example, aortic, mitral, tricuspid and / or pulmonary prosthetic valves can be delivered to the treatment site using minimally invasive surgical procedures or transcatheter techniques. [0005] The introducer system can...
