Abstract

Disclosed herein are expandable introducer sheaths and methods of making and using the same. The sheaths minimize trauma to a patient's vasculature by allowing for temporary expansion of a portion ofthe sheath to accommodate passage of a delivery system for an implant, then return to a non-expanded state after the passage of the device. The sheath includes a foldable inner member having a detached flap structure at its distal tip that facilitates expansion of the sheath lumen to increased diameters, and an elastomeric distal end that reduces push and retrieval forces therethrough. The sheathcan include a hemostasis seal on its proximal end to prevent the leakage of blood out of the sheath and prevent ballooning of outer layer of the sheath.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 522,986, filed June 21, 2017, which is incorporated by reference in its entirety for all purposes. technical field [0003] The present application relates to embodiments of sheaths for use with catheter-based techniques to introduce prosthetic devices, such as heart valves or other implants, into a patient's vasculature. Background technique [0004] Intravascular delivery catheter assemblies are used to implant prosthetic devices, such as prosthetic heart valves, in locations within the body that are not readily accessible or are desired to be accessed without invasive surgery. For example, the aortic, mitral, tricuspid, and / or pulmonary prosthetic valves can be delivered to the treatment site using minimally invasive surgical techniques, including transcatheter delivery methods. [0005] An introducer sheath can be used to safely introduce t...
