Embodiment Construction

[0058] Certain illustrative embodiments will be described in order to provide an overall understanding of the systems, methods, and devices described herein. Although the embodiments and features described herein are specifically described for use in conjunction with a percutaneous heart pump system, it should be understood that the components and other features outlined below may be combined with each other in any suitable manner and may be adapted and applied to other types of heart pump systems. Medical devices such as stents, transcatheter aortic valve replacement (TAVR) delivery systems, cardiac therapy and cardiac assist devices, including balloon pumps, cardiac assist devices implanted using surgical incisions, and other vascular devices.

[0059] The systems, methods and devices of the present disclosure provide an irrigation sheath assembly for insertion into a blood vessel of a patient. The sheath assembly includes a lumen configured for passage of a medical device. ...

Abstract

A persistent perfusion sheath assembly can be used for the passage of an intravascular medical device while maintain a flow passage in the vessel. The sheath assembly passes through an arteriotomy and can include a first lumen configured for the passage of a medical device, a second lumen configured to allow a flow of fluid from a location in the blood vessel upstream of the arteriotomy to a location downstream, of the arteriotomy. The sheath assembly can further include a stylet, a sleeve or an additional sheath configured to selectively open and close the flow of blood between upstream and downstream of the arteriotomy. The sheath assembly can further include a closure device distal of the arteriotomy, the closure device configured to control blood flow through the arteriotomy.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Patent Application Serial No. 62 / 783,554, filed December 21, 2018, the contents of which are hereby incorporated by reference in their entirety. Background technique [0003] Intravascular medical devices (such as percutaneous pumps (e.g., Impella 2.5 from Abiomed, Danvers, MA) TM systems), catheters, guidewires, balloon angioplasty catheters, delivery sheaths, and implant delivery systems) are commonly used during minimally invasive procedures in the cardiovascular, cerebrovascular, and peripheral vasculature. Such medical devices can be introduced into a patient in a variety of ways. During cardiac surgical procedures, blood pump assemblies are introduced surgically or percutaneously through the vascular system. This endovascular procedure is minimally invasive. In one common approach, a pump assembly is inserted through the fem...
