US 9,539,090 B2 · Transaortic valve access device

Abstract

A valve insertion device for traversing a wire guide through a valve within an intraluminal passage. A wire guide is positioned near the outflow of a valve within an intraluminal passage. Alongside the wire guide, a pressure sensor is positioned to detect the pressure of the fluid in the intraluminal passage. As the valve opens, the fluid pressure at the outflow of the valve increases. This information is sent from the pressure sensor to a control system. From this information, the control system can determine when the valve will open and can actuate an advancement system to move the wire guide to traverse the open valve. After traversing the valve, various catheters and sheaths may be advanced over the wire guide through the valve.

Dependent claims

A valve insertion device comprising,

a wire guide having proximal and distal portions;
a pressure sensor positioned near the distal portion of the wire guide, wherein the pressure sensor detects fluid pressure information of an area within an intraluminal passage near a valve;
an advancement system coupled to the wire guide wherein the advancement system is configured to move the distal portion of the wire guide through the valve;
and
a control system configured to receive the fluid pressure information from the pressure sensor to determine when the valve is open, and actuate the advancement system to move the distal portion of the wire guide through the valve when the valve is open.
