Problems solved by technology

However, if left for longer periods of time (e.g., >1 hour, >2 hours, >6 hours, >1 day, >2 days, >1 week), blood clots may form on the outer surface of the expandable sheath mesh on, and risk entering the bloodstream over time
Additionally, some commercially available expandable sheaths are completely flexible and therefore do not provide any stiffness within their structure, causing kinks or buckling during insertion or removal of the percutaneous medical device

Abstract

An introducer sheath (200) for the insertion of a medical device into a blood vessel having an expandable sheath. The sheath has a length, a thickness, and proximal and distal ends. The expandable sheath has a frame extending longitudinally between the proximal end and the distal end, and having an exterior surface and an interior surface that forms an interior lumen along the length of the frame.The frame is configured to achieve an expanded state and a contracted state, the expanded state forming an expanded cross-section in the lumen for passing a medical device therethrough. The frame hasa smooth coating about the exterior surface and protrusions extending into the lumen along the interior surface.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application No. 62 / 718,681, entitled "Expandable Introducer Sheath for Medical Device," filed February 15, 2018, and claims Priority to U.S. Patent Application No. 62 / 631,404, filed February 15, 2018, entitled "Expandable Introducer Sheath for Medical Device," each of the aforementioned applications The entire contents of , including Appendices A to C, are incorporated herein by reference. Background technique [0003] An intracardiac heart pump assembly can be surgically or percutaneously introduced into the heart and used to deliver blood from one location in the heart or circulatory system to another location in the heart or circulatory system. For example, when deployed in the heart, an intracardiac pump may pump blood from the left ventricle of the heart into the aorta, or from the inferior vena cava into the pulmonary artery. The intracardiac pump can be powered by ...
